1. Introduction
The Washington County Water Conservancy District (WCWCD) intends to construct a new surface water
treatment plant using raw water from Gunlock Reservoir to supplement local potable water supplies. The
plant, currently named the West Side WTP (WSWTP), will have a capacity of 10 to 15 mgd and address
the critical demand for more drinking water on the west side of Washington County.
Figures 1.1 and 1.2 show proposed pilot test treatment configurations for the new WSWTP. If phase 1
performs well within the first 12 months, testing will continue until the 18th month without transitioning
to phase 2. If phase 1 does not meet expectations in the first 12 months, phase 2 will be activated and
tested from the 13th to the 18th month. During piloting, the District will continue conducting monthly
bench tests to fine-tune pilot treatment parameters.
Figure 1.1 Phase 1 Pilot Test Treatment Configuration for WSWTP

July 16, 2025
West Side WTP Pilot Plan Page 7

Figure 1.2 Phase 2 Pilot Test Treatment Configuration for WSWTP

Phase 1 Pilot Test (12 or 18 months, see Figure 1.1):
The pre-sedimentation units will be a tank with plate settlers designed to reduce high solids, turbidity, and
suspended organics levels in the source water — particularly during seasonal events such as releases from
Baker Reservoir or storm runoff. The DAF process, enhanced by coagulation and flocculation, will
effectively remove algae, organic matter, and turbidity. Ozone treatment will target color, taste, and odor
issues, as well as emerging contaminants such as cyanobacteria. Additionally, ozone will oxidize arsenic,
dissolved iron, and manganese, enabling their removal by downstream dual-media filters.
Phase 2 Pilot Test (Possible 6 months, see Figure 1.2):
The piping will be reconfigured to take the ozone and filters in Enclosure 1 and the DAF system in
Enclosure 2 offline. The mixer in the pre-sedimentation tanks will be activated, converting them into
conventional flocculation/sedimentation (F/S) tanks. Enclosure 3, containing the ultrafiltration (UF)
system, will be connected to bring UF online.
The pilot study aims to:
 Confirm the feasibility of the treatment process and optimize chemical and operational
parameters to meet treatment goals.
 Evaluate key components, including:
Phase 1
o Pre-sedimentation loading rates
o DAF performance (chemicals, rapid mix, coagulation, flocculation, flotation)
July 16, 2025
West Side WTP Pilot Plan Page 8

o Ozone performance (need for advanced oxidation with hydrogen peroxide, ozone
demand and decay, pre-ozonation and intermediate ozone)
o Filtration efficiency for two different depth configurations
Phase 2
o Conventional F/S performance (chemicals, rapid mix, coagulation, flocculation,
sedimentation)
o UF efficiency
 Determine if pre-oxidation at the flash mix stage is necessary for the recommended process.
The proposed pilot equipment requires three enclosures as shown in Figure 1.1 and 1.2. Pilot Enclosure 1
will be provided by Hazen and Sawyer. Enclosure 2 with the DAF unit will be provided by Intuitech.
Enclosure 3 with UF membrane will be chosen based on vendor’s availability, prior project experience,
and overall cost. Appendix A includes UF pilot proposals from three vendors. Hazen staff will operate the
pilot with assistance from WCWCD staff. The ideal time to pilot is during algae bloom season, runoff
when maximum raw water turbidity occurs, and late summer when peak demand occurs and maximum
filtration rate would be experienced. The location of ozone and DAF in phase 1 test will be switched
during high algae and turbidity events to evaluate the performance of different treatment configurations
(pre- vs intermediate ozone).
Gunlock Reservoir recorded its highest pH level (9.26) on 4/30/25 under the current sampling plan
(Appendix B). Historical alkalinity levels have consistently exceeded 120 mg/L, with most measurements
above 156 mg/L (Appendix B).
Bench testing (Round 1, Appendix C) showed that 30 mg/L ALUM + 0.5 mg/L polymer achieved 27%
TOC removal in DAF jar tests. Notably, similar efficiency (~23%) was maintained at a lower ALUM
dose (20 mg/L) when polymer was increased to 1 mg/L. While the 40 mg/L ferric chloride + 0.5 mg/L
polymer combination delivered the highest TOC removal (33%), ALUM was selected as the primary
pilot-scale coagulant due to its substantial cost advantage ($2/gallon vs. ferric chloride’s $11/gallon). To
evaluate seasonal influences, both ALUM + polymer and ferric + polymer will be tested during piloting.
Both coagulants reduced alkalinity, stabilizing pH within optimal ranges: 6.5–7.0 for ferric chloride and
7.0–7.5 for ALUM. The pilot study will evaluate performance both with and without pH adjustment
during the testing period. Pilot staff will monitor finished water pH and assess whether future full-scale
treatment will require pH modification. Finished water from the pilot system will be directed to the
nearby drainage. Disinfection is unnecessary, but pH correction could be needed.
This plan outlines the tasks to be completed during the pilot study and establishes a framework for
testing. The approach may be adjusted based on operational observations and pilot results.

1.3 Pilot Schedule
Phase 1 and phase 2 will be piloted for a total period of 18 months from approximately October 2025 to
May 2027. The estimated installation, training, and start-up time is approximately one week. Upon
completion of the pilot study, the pilot testing equipment will be disassembled and returned to their
respective owners (Hazen or Intuitech or UF vendor). Throughout the pilot operation, there will be
continuous monitoring of water quality parameters along with specific sampling periods when more water
quality analyses will be conducted.
Hazen will submit the Draft Pilot Study Report to WCWCD in August 2027. WCWCD will review the
report and provide comments to Hazen in September 2027. Hazen will incorporate WCWCD’s comments
into the Final Draft Filtration Pilot Study report and submit the report to DDW for review in early
October 2027.
1.4 Key Contacts and Meetings
During pilot operations, WCWCD staff will provide support with after-hours response to alarms as
needed. Table 1-2 provides a list of the pilot plant key contacts.

the subsequent week.
1.5 Safety
Safety at the pilot facility is top priority for WCWCD and Hazen. All staff conducting activities at the site
will operate under WCWCD’s safety requirements that are already in place at the Quail Creek WTP and
the City of St George’s Gunlock WTP (pilot location). General safety precautions will be taken when
operating equipment and using personal protection equipment (PPE). The key hazards that require special
attention to safety are as follows:
 Spills and exposure to treatment chemicals
 Slips, trips, and falls
July 16, 2025
West Side WTP Pilot Plan Page 12

Spills and exposure to treatment chemicals
The pilot unit will have a portable eyewash station and a chemical spill kit in each enclosure.
To manage the hazard of chemical exposure in the event of a spill, a list of the chemicals used in the pilot
operations will be stored on-site. This list is provided in Appendix D and will be updated if any additional
chemicals are selected for evaluation or use at the pilot. Safety Data Sheets will be printed and stored on-
site. Any chemical spills will be immediately cleaned up to avoid creating a slippery surface and exposure
hazard.
Slips, trips, and falls
Proper signage will be displayed to warn operators or trip or fall hazards. Operators will wear appropriate
PPE to reduce the risk of hazards.
Ozone gas
To reduce the risk of ozone gas exposure, the enclosure containing the ozone module includes audio and
visual alarms. The ozone skid will include an alarm on the control panel. Enclosure 1 will also include an
external beacon and an alarm. There are also two ambient ozone monitors that will turn off the ozone
module if the ambient ozone concentration exceeds 0.1 mg/L for 8 hours or 0.3 mg/L instantaneously, per
the Occupational Safety and Health Administration (OSHA) thresholds. The enclosure exhaust fan will
also turn on and the louver will open. A visual and audio alarm will signal from outside the enclosure if
levels exceed the OSHA thresholds.
Working environment
The pilot unit will be located near the existing drying beds at Gunlock WTP. The pilot unit is temperature
controlled with heating and cooling; therefore, temperature concerns are not a specific hazard for the
working environment.
Appendix E contains the complete safety plan that will always remain on site during pilot operations.
2. Pilot Process Description
The following treatment processes were selected for the pilot study:
Phase 1
 Pre-sedimentation tank with plate settlers
 Rapid mix, flocculation and clarification (DAF with floated solids skimming)
 Ozone (pre-ozonation or intermediate ozonation) with ambient air as the oxygen source
 Granular dual-media filtration
Phase 2
 Conventional F/S tank with plate settlers
 Rapid mix, flocculation and sedimentation
 UF membrane filtration
July 16, 2025
West Side WTP Pilot Plan Page 13

This section provides an overview of the pilot plant process flow diagram, sampling locations, and pilot
unit specifications.
3. Pilot Unit Location and Site Development
This section describes the general arrangements of the pilot plant facilities, and the infrastructure systems
required to support pilot plant operations.
3.1 Site Location
The pilot unit will be located at Gunlock WTP near the existing drying beds. Figures 1.3 and 1.4 show the
existing Gunlock WTP vicinity plan and a preliminary layout for the pilot enclosures, respectively. When
phase 1 test is completed, enclosure 3 with UF will replace enclosure 2 to continue the phase 2 test. The
same influent and effluent piping will be used for both phase 1 and phase 2 tests.
3.2 Site Utilities
The following utilities will be utilized for the pilot.
3.2.1 Intake Pump
Raw water flow by gravity from the existing Filter Station to the pre-sedimentation pilot skid pumping
well and then pumped to the inlet connection using a submersible pump provided by Hazen.
3.2.2 Electricity
The pilot unit requires a continuous single-phase 480V power supply. WCWCD will power from the
adjacent Filter Station.
3.2.3 Connectivity
The pilot will have a secure mobile broadband connection to facilitate remote monitoring and operations.

West Side WTP Pilot Plan Page 16

3.2.4 Solids Management
The primary waste streams from the pilot facility will come from settled solids from the pre-
sedimentation unit, skimmed float from the DAF process, overflow from any unit, and the filter backwash
water. These waste streams will be routed through a buried temporary pipe to the existing sludge drying
beds. No settling or equalization tank will be installed for the pilot skid, given the minimal influence of
sludge on the existing Gunlock WTP.
The treatment chemicals used in the pilot treatment process will be NSF International (NSF)-60 approved
for potable water consumption and will be used at doses below the NSF-60 potable water maximum use
limit (MUL). Testing reagents, like N, N-diethyl-p-phenylenediamine (DPD) for free chlorine testing, will
be disposed of separately from the solids waste stream.
3.3 Pilot Plant Process
Phase 1 Pilot Treatment Train:
The initial treatment train for Phase 1 will include pre-sedimentation (using plate settlers), DAF,
ozonation, and dual-media filtration (sand/anthracite). Hazen pilot enclosure 1 will contain the pre-
sedimentation, ozone, and filtration units, while Intuitech pilot enclosure 2 will accommodate the DAF
system. To evaluate alternative treatment configurations during high algae and turbidity events, pre-
ozonation (highlighted in green) will be tested as an optional setup. A detailed process diagram of the
Phase 1 layout is provided in Figure 1.5.
Phase 2 Testing (UF Integration):
DAF in enclosure 1, ozone unit and filtration in enclosure 2 will be taken offline after phase 1. For phase
2, enclosure 3 with UF unit will be connected to enclosure 1, as illustrated in Figure 1.2.
All three enclosures will be outfitted with instrumentation to track system performance and key water
quality parameters, such as flow rate, turbidity, pH, and temperature. The subsequent sections summarize
the key unit specifications for all standard pilot units. P&IDs of each pilot unit are included in Appendix
F.

3.3.1 Hazen Pilot Enclosure 1 - Pre Sedimentation Unit
The pre-sedimentation pilot unit includes a settling tank equipped with plate settlers to prevent short-
circuiting and ensure uniform settling. The design criteria are shown in Table 1-3. A general layout of
Hazen’s floc/sed skid is shown in Figure 1.7. All mixers will be turned off to work as a pre-sedimentation
tank, which will be always online to test both high- and low-rate sedimentation operations. The pilot
system will bring 18 gpm as the influent and send back overflow (9 gpm) after pre-sedimentation tank to
test the loading rate.
No chemicals will be dosed at the pre-sedimentation tank. Intuitech recommends that downstream
processes being supplied by the settled water tank have a flow rate of 0.25-0.5 gpm lower than the
upstream process to ensure that the downstream process has flooded suction to the feed pumps.

3.3.2 Intuitech Enclosure 2 - DAF Pilot Unit
The pilot unit will be capable of operating at a DAF loading rate of approximately 6 gpm/sf (full-scale
DAF may be designed to 8 gpm/sf). The DAF recycle rate can be adjusted up to 12%. Rapid and
flocculation mixers are variable speed, with speed correlated to velocity gradients in the mixing vessels.
Coagulant (ALUM) and coagulant aid polymer can be added to each stage of rapid mixing and
flocculation. Online instruments will continuously record process flow, filter head loss and raw, floated,
and filtered pH, turbidity, and temperature. The following loading rates will be piloted. A general layout
of Intuitech’s DAF skid is shown in Figure 1.8. The system’s design criteria are outlined in Table 1-4.

3.3.3 Hazen Pilot Enclosure 1 - Ozone Pilot Unit
The ozone pilot unit can operate in either pre- or intermediate ozone configurations. Using pre-ozone with
stacked DAF above the filters (DAFF) could reduce clarification requirements and footprint by up to
40%. Alternatively, an intermediate ozone configuration would employ DAF followed by ozone then dual
media filters to reduce ozone demand. The pilot system’s design criteria are outlined in Table 1-5. A

3.3.4 Hazen Pilot Enclosure 1 - Filter
The filtration pilot unit consists of four filter columns with max flow rate of 5.2 gpm in total. Figure 1.10
provides a general layout of Hazen’s typical four-filter unit. The pilot system’s design criteria are outlined
in Table 1-6. The unit includes an individual feed pump for each filter column, a backwash system, and
an air scour system. Each filter flows independently. Only one filter can be backwashed at a time. The
unit provides four chemical feed systems for the ability to feed a filter aid, pre-oxidant, or reducing agent
to all four filters. Filter backwashing can be controlled manually or initiated automatically based on run

3.3.5 Filter Media Configuration
Each filter column will have one of two filter media configurations. The pilot loading rates for the filters
are 6 gpm/ft2 and 8 gpm/ft2. A description of the proposed filter media configuration is provided in Table
1-7. A key design criterion for filtration is the L/d ratio, which is the bed depth, L, divided by the average
filter grain effective size or diameter, d. Industry practice is to choose a total filter L/d ranging between
approximately 1,500 and 2,000 for high-rate coarse grain media filters (Kawamura, 2000). The L/d ratio
for the two proposed anthracite and sand media configurations are 1,469 and 1,616, respectively. The
filter media will be sent directly from the media supplier to Hazen for preliminary soaking, washing, and
installation into the filter columns. A sieve analysis will be performed on the media by the media
manufacturer and the sieve analysis results will be provided with the filter media.
Upon achieving the treatment goals, WCWCD proposes converting one of the existing filters into a
biologically active filter to assess its operational feasibility and treatment performance. The filer media
will be provided by nearby Quail Creek WTP. This pilot initiative will help evaluate potential long-term
benefits, including enhanced filtration efficiency and possible reductions in chemical usage.

4. Pilot Operations
This section describes the overall pilot plant testing strategies used to validate plant design criteria in a
manner consistent with the goals set forth in this study. Variables affecting pilot plant performance
include variable raw water quality characteristics and numerous operational parameters that can be
manipulated in the pilot plant facilities.
The pilot plant facilities are intended to operate continuously. Continuous operation will allow for
continuous collection of valuable operating and performance data using in-house analytical equipment
and data continuously recorded by the pilot plant equipment. The pilot plant facilities will be staffed 2 to
8 hours during normal business hours and will be left to run automatically during evening and weekend
hours.
Water quality data will be collected throughout the pilot duration as a part of the sampling program.
Section 1.4.5 describes the sampling plan and specific water quality parameters to be evaluated.
4.1 Equipment Delivery
Hazen and Intuitech will deliver the pilot phase 1 equipment to the site on October 27, 2025. The UF
vendor will deliver the pilot phase 2 equipment after phase 1 is completed. WCWCD will provide a crane
to lift the pilot enclosure off the shipping truck. The site will be leveled before pilot equipment arrives
and the pilot enclosures will sit on railroad ties and shims (as needed) to provide a level installation. The
following piping is needed to connect to Enclosure 1:
 Raw water piping (approximately 400 linear feet (LF), 1.5-inch-diameter) from the Filter
Station.
 One run of approximately 400 LF of 2-inch waste discharge piping from the sludge drying
beds to the combined pilot unit pre-sedimentation solids, float skim from DAF process,
overflow from any process, and the filter backwash water.
 One run of approximately 400 LF of 2-inch filter effluent line to Filter Station.
 One run of approximately 400 LF of 2-inch overflow line from pre-sedimentation to Filter
Station.
 Hose connection to potable water.
Upon arrival of the pilot plant equipment, staff will inspect it carefully for damage during shipping.
4.2 Installation and Startup
Upon phase 1 delivery, the Hazen team will install the equipment. The installation of the equipment is
proposed for the week of October 27, 2025. After installation, Hazen and Intuitech will provide
equipment training for enclosures 1 and 2 respectively, including maintenance and troubleshooting
instructions. Operations and maintenance (O&M) manuals will be provided for the equipment including
individual equipment O&M manuals. Installation and training are expected to last one week, which will
involve installing and connecting all pilot equipment, and establishing proper equipment operations
(including chemical feed pumps, automated valves and solenoids, data logging, and confirming remote
July 16, 2025
West Side WTP Pilot Plan Page 27

operating controls and monitoring equipment). Phase 2 (enclosure 3) delivery will be arranged before
phase 1 test is completed.
The pilot operations team will complete verifications to confirm that all components and instruments are
securely mounted, and piping connections are secure. The team will install the feed water supply for the
pilot equipment, ensuring pipelines and any appurtenances are installed according to Hazen
specifications. During this period of pilot plant installation and startup, the Hazen team will also complete
other startup activities such as:
 Filling chemical feed tanks
 Determining proper operation of waste-stream processes
 Finalizing sampling protocols and data logging datasheets
 Calibrating instrumentation, chemical feed pumps, and/or other laboratory equipment and pilot
devices
4.3 Equipment Operation
The following section provides an overview of the operational procedure for the pilot units phase 1 and 2
tests. Raw water will flow by gravity from the pressurized line at the Filter Station to enclosure 1. Raw
water flow will be routed to a standpipe where excess flows not needed by the pilot plant are directed to
the overflow line. Raw water feed flow, temperature, and turbidity will be continuously measured by
online analyzers.
4.3.1 Phase 1 Pre-sedimentation and DAF
The pre-sedimentation tank will operate continuously to effectively remove heavy solids and settleable
particles from the influent stream. Overflow from pre-sedimentation tank will be sent back to the existing
Filter Station drain. This passive treatment step functions without chemical addition, relying solely on
gravity separation by plate settlers to reduce the load on downstream processes. By maintaining consistent
operation, the tank enhances overall system resilience while minimizing operational complexity and
chemical costs.
The DAF unit consists of rapid mix, flocculation, and flotation, which is operated using the integral
control panel. Rapid mix energy inputs will be adjustable. Likewise, flocculation mixing energy levels
will be controlled for each stage to achieve a tapered flocculation process. Detention time in the
flocculation process may be varied by bypassing one or more of the individual flocculation stages. The
DAF recycle rate varies between 8-12% (Table 1-4). Pilot operators will change rapid mix and
flocculation mixing energies and DAF recycle rate as needed to optimize physical floc characteristics,
clarified water turbidity, and filtration performance.
Coagulant and coagulant aid chemicals will be dosed at the rapid mix system to facilitate colloidal
destabilization, followed by flocculation and flotation. The chemicals will be flow paced. Clarification
loading rate is anticipated to remain the same for the duration of the study.
July 16, 2025
West Side WTP Pilot Plan Page 28

Settled water turbidity and pH will be continuously recorded by online analyzers, and solids skimming
will be performed intermittently. A bench top Zetasizer may be used as a tool for assisting with
optimization of the process.
Table 1-10 is a summary of the anticipated operating parameters used at the start of the pilot. These
parameters may change based on treatment performance observed throughout the pilot.

Sedimentation SOR 0.3 gpm/ft2
Filter Loading Rate 8 - 10gpm/ft2
Notes: 1 Chemical dosage starting values are raw water quality dependent.
4.3.2 Phase 1 Filtration
Each filter operates independently and includes automatic flow control. The filters can be backwashed
automatically based on run time, head loss, or effluent turbidity. An operator may also manually initiate a
backwash. Only one filter may be backwashed at a time, but filters can be backwashed sequentially (one
after the other). For each filter, the unit filtration rate, head loss, and filtered water turbidity will be
recorded continuously. Filter-to-waste can be terminated based on time and/or turbidity.
Table 1-11 shows the proposed backwash criteria. If one criterion is reached, a backwash will be initiated.
Throughout the pilot study, the backwash and air scour sequence and protocol will remain relatively
constant. The filter-to-waste cycle will end when the turbidity drops below the desired goal. This goal
may be adjusted if filtration is not optimized and backwash water is needed. The turbidity of the filter-to-
waste water will be recorded continuously.
Filter-to-waste flows will be diverted to the pilot drain line and not the filtered water/backwash
supply tank. Air scour and backwash rates may be adjusted and documented in the field to achieve
30 percent bed expansion.
This pilot study will not focus on backwash optimization because the small columns are not
representative of full-scale filters. Backwash followed by the start of a filtration run is designed so that it
July 16, 2025
West Side WTP Pilot Plan Page 29

can be completely automated to allow continuous operation. Filter aid can be dosed to each individual
filter to compare performance with and without filter aid and varying dosages.
Table 1-11: Backwash Initiation Criteria and Operation

Maximum head loss 12 ft
Maximum filter run time 100 hours

Low backwash flow time and rate 5 minutes of water at 6 gpm/sf
Quiescent settling time 10 minutes
Filter-to-waste Minimum filter-to-waste timing of 5 minutes, and until filtrate turbidity is ≤
0.1 NTU
Note: backwash criteria may be modified in the field during start-up to achieve desired filter bed expansion.
4.3.3 Phase 2 UF
The UF process is a pressure-driven process. Filtrate is sent to the backwash supply tank. Backwashing
is used to remove accumulated foulants by reversed inside/out flow at an interval of 20 - 60 minutes
with air scour for increased agitation. A drain or filter-to-waste step is used to remove any additional
accumulated material. Membrane integrity testing is conducted automatically once every 24 hours. The
pressure decay test can detect a single fiber break. Criteria have been included in Table 1-9.
Maintenance cleans/chemically enhanced backwashes and CIP procedures are automated chemical
cleaning processes used to recover membrane permeability. Maintenance cleans/chemically enhanced
backwashes are typically performed with NaOCl once per day to once per week. The automated clean-
in-place procedure is designed to occur no more frequently than once per month, is conducted with
either NaOCl or acid and is initiated when membrane permeability decreases to a specified value.
Following chemical cleaning procedures, the membrane units are drained by gravity or a pressurized
drain-to-waste, and waste is subsequently sent to the discharge location. A rinse step and backwashing
are used to remove residual chemicals prior to resuming production.
4.4 Anticipated Pilot Plant Operation Schedule and Testing Plan
The plan is to operate the pilot plant continuously 24 hours per day and 7 days per week. There may be
times when the pilot is shut down for equipment repair or extenuating circumstances. The pilot plant
July 16, 2025
West Side WTP Pilot Plan Page 30

facilities will be staffed approximately 20 hours per week during normal operations but monitored daily
via remote connection. WCWCD will use AT&T or Verizon cellular to monitor the system remotely.
Initial testing will focus on chemical selection and doses to address impacts on overall performance.
Table 1-12 shows the anticipated testing plan for two phases. If phase 2 is not needed, the phase 1 test
will be extended to the 18th month.

The pilot team will collect water quality data throughout the duration of the study at varying frequencies
depending on the parameter. Samples will either be grab samples or automatically measured using online
analyzers. Some parameters are collected to compare operational goals and performance benchmarks,
while others are for process control only. Analysis equipment will be periodically tested to confirm they
are within allowable values. Calibration of equipment will occur at the beginning of the pilot and as
needed through the study.

Design Information
Water Quality
WesTech UF systems will consistently produce high-purity treated water even with variation in the
feed source due to a small nominal pore size in an absolute barrier configuration.
Feed Water Quality*
Parameter Unit Value / Description
Source - Surface Water
pH - 6.5 – 8.5
Temperature °C 2 – 20
Turbidity NTU < 5
Total Suspended Solids mg/L < 5
Total Organic Carbon mg/L < 3
Iron mg/L < 0.3
Manganese mg/L < 0.05
*Values are assumed and should be verified. The use of charged polymeric flocculant aids increases risk of irreversible
membrane fouling and should not be used without prior written approval. This risk is applicable to all polymeric MF/UF membrane manufacturers. The presence of oil and grease in the source water must be minimized and may void any
applicable warranty.
Treated Water Quality
Parameter Unit Value / Description
Turbidity NTU ≤ 0.10 NTU 95% of the time with a maximum
turbidity of 0.3 NTU
Total Suspended Solids mg/L < 1
Silt Density Index - ≤ 3
Giardia Removal* - ≥ 4 log (99.99%)
Cryptosporidium Removal* - ≥ 4 log (99.99%)
Virus Removal* - ≥ 1.0 log removal (90.00%)
Certification Standards NSF/ANSI 61, NSF/ANSI 419, UL 508A Listed
Turbidity NTU ≤ 0.10 NTU 95% of the time with a maximum
turbidity of 0.3 NTU
*Challenge-testing certification is provided by independent evaluation through NSF/ANSI 419. Typical removal levels
exceed the certification level and are often on the order of 6-log. Additionally, the UF membranes achieve 1.5 log removals
of viruses, though virus removal certification is only recognized up to 1.0 log by CDDW for any membrane filter.

Technical Proposal
Proposal: 2530117.B_Rev0 6
Process Description
Described in this proposal is the process and design of the WesTech pilot membrane filtration
system for the West Side WTP project. The system design consists of one (1) pilot skid with 3-
module capacity, sized to achieve 20 – 30 gpm based on the water quality.
The filtration process is an outside/in, pressure-driven process to remove suspended solids and
turbidity, and to achieve 4-log reduction of pathogens like Giardia and Cryptosporidium.
Ultrafiltration membranes can also achieve >1.5 log reduction of waterborne viruses.
Filtrate is sent to the backwash supply tank. Backwashing is used to remove accumulated foulants
by reversed inside/out flow at an interval of 20 - 60 minutes with air scour for increased agitation.
A drain or filter-to-waste step is used to remove any additional accumulated material. Membrane
integrity testing is conducted automatically once every 24 hours. The pressure decay test (PDT) is
capable of detecting a single fiber break.
Maintenance cleans (MCs)/chemically-enhanced backwashes (CEBs) and clean-in-place (CIP)
procedures are automated chemical cleaning processes used to recover membrane permeability.
MCs/CEBs are typically performed with NaOCl once per day to once per week. The automated
clean-in-place procedure is designed to occur no more frequently than once per month, is
conducted with either NaOCl or acid and is initiated when membrane permeability decreases to a
specified value.
Following chemical cleaning procedures, the membrane units are drained by gravity or a
pressurized drain-to-waste, and waste is subsequently sent to the discharge location. A rinse step
and backwashing are used to remove residual chemical prior to resuming production.

Executive Summary

The Washington County Water Conservancy District (WCWCD) is planning to construct a new 10-15 MGD
surface water treatment plant using raw water from Gunlock Reservoir to supplement local potable water
supplies. Hazen and Sawyer has been engaged to conduct water quality analysis, pilot testing, and site
evaluation to inform the plant's design. This report summarizes historical water quality data, identifies key
treatment challenges, and proposes a comprehensive sampling plan to address data gaps and ensure
data-driven design of a resilient treatment train for pilot testing.
I. Key Findings
Water Quality Stability: Generally favorable, with TDS (<500 mg/L), sulfate (<105 mg/L), and most
inorganic contaminants below regulatory limits.
Concerns:
pH Fluctuations (6.7-9.1): May require adjustment to meet Utah DEQ standards (6.5–8.5) and to optimize
treatment processes.
Total Phosphorus (TP) (exceeding 0.025 mg/L in >40% of samples): Linked to algal blooms, necessitating
treatment train selection for potential algae removal.
Arsenic (up to 44.3 µg/L): Exceeds the 10 µg/L limit; coagulation during bench and pilot testing will be
evaluated.
Iron/Manganese: Exceeds the 300 µg/L iron and 50 µg/L manganese limits; Oxidation and filtration during
bench and pilot testing will be evaluated.
Seasonal Algae Variability: Dominant species shift annually, requiring adaptable treatment (e.g., oxidation,
filtration).
Corrosion control may be needed for finished water.
II. Recommended Actions
Sampling Plan:
Frequency: Monthly for most parameters; weekly for critical variables (pH/Temperature, UV254,
turbidity, etc.).
Cost: Estimated at $60,000 annually including contingency.
Design Considerations for Gunlock Intake:
Below thermocline for stable temperature/TSS.
III. Conclusion
Gunlock Reservoir is a typical surface water with occasional high turbidity events. The suggested sampling
strategy will inform an effective process assessment during bench and pilot testing. Proactive monitoring
and adaptive process selection will be critical to meeting Utah DEQ standards and ensuring long-term water
quality reliability.

1. Background

The Washington County Water Conservancy District (WCWCD) is a water conservancy district established
under the Utah Water Conservancy District Act. Historically, Gunlock Reservoir is located near the town of
Gunlock on the Santa Clara River. Gunlock Reservoir is the largest water storage impoundment (221 acres)
on the Santa Clara River. Water is captured in Gunlock Reservoir and stored for downstream domestic and
agricultural uses throughout the year. The reservoir is also used for recreation (boating, fishing, etc.) and
by livestock grazing along the shores.
WCWCD plans to construct a new surface water treatment plant (10-15 MGD) within the next decade, using
raw water from Gunlock Reservoir to supplement the local potable water supply. WCWCD has selected
Hazen and Sawyer as the qualified design professional for the West Side Water Treatment Plant Piloting
and Site Evaluation project. This involves collecting necessary water quality data, developing a piloting
plan, conducting pilot testing, performing site alternatives analysis, and providing land acquisition support
for the treatment plant and associated infrastructure.
The Utah DEQ conducted water quality monitoring in the vicinity of Gunlock Reservoir from 1979 to 2019
at the sampling location illustrated in Fig. 1. All samples at sites 4950500 and 495530 were collected from
the river surface. Most samples at stations 4950510 and 4950520 were collected from the lake surface,
while a few were taken at varying depths ranging from 2 to 29 meters. WCWCD has been monitoring
Gunlock Reservoir near the beach access and collecting samples from the surface.
The 2004 Total Maximum Daily Load Water Quality Study of the Virgin River Watershed1 (2004 TMDL)
summarized Utah DEQ and USGS sampling stations in the Santa Clara River sub watershed from the
1970s to 2002.
Given the limited availability of historical water quality data, this sampling plan will focus on analyzing
existing data and developing a comprehensive water quality sampling strategy to inform pilot testing and
future treatment plant design. The plan will account for historical water quality trends and their potential
impacts on treatment process selection, including turbidity, natural organic matter (major DBP precursors),
seasonal algae blooms, and others. Based on the water quality data, Hazen will conduct a treatment
process analysis to identify the most cost-effective technologies for producing high-quality treated water.

Figure 1. Historical Utah DEQ and WCWCD Sampling Stations in the Vicinity of Gunlock Reservoir
Hazen will receive, review, and analyze both historical and new water quality data. This information will be
used to determine the most suitable treatment trains to deliver safe, high-quality potable water for residents.
The sampling data will include source water natural organic matter loading (TOC/DOC, UV254, and other
relevant water quality parameters that are listed in the separated spreadsheet [see Appendix A]).
2. Historical Data Analysis in Gunlock Reservoir
Sources of water quality constituent loadings around the Gunlock Reservoir were natural hill-slope erosion,
livestock grazing and dispersed recreational uses. All available historical data has been summarized as
follows.
pH and Temperature
The pH data for these stations are summarized in Figure 2. The pH values varied between a maximum of
9.1, measured on July 27, 2005, at the Santa Clara River above the reservoir, and a minimum of 6.7,
measured on November 13, 2008, at the Santa Clara River below the reservoir. pH levels above 8.5 were
recorded at all four sampling sites. As a result, pH adjustment in the new WTP may be required to meet the
Utah DEQ’s recommended range of 6.5 to 8.5 and to optimize treatment processes.
The efficiency of one of the key water treatment steps, coagulation, is greatly dependent on water
temperature. Historically, temperature readings ranged from a high of 27.4°C, recorded on July 27, 2005,
at the Santa Clara River above the reservoir, to a low of 2.3°C, recorded on January 30, 2008, at the Santa

Clara River below the reservoir (Figure 3). It is worth noting that on the same day, some samples at
GUNLOCK RES ABOVE DAM 01 (4950510) were collected from the surface, above, and below the
thermocline. Since the intake for the new WTP is expected to be located below the thermocline, the
temperature is anticipated to remain within a relatively stable range.

Figure 2. pH Historical Sampling Data

Figure 3. Temperature Historical Sampling Data

Hazen and Sawyer
10619 South Jordan Gateway, Suite 130,
South Jordan, UT 84095
Turbidity
The turbidity data for these stations are summarized in Figure 4. Monitoring was conducted only at SANTA
CLARA RIVER BELOW GUNLOCK RES (4950500) and GUNLOCK RES ABOVE DAM 01 (4950510) from
1979 to 2013. Turbidity samples from the Santa Clara River were collected from the surface. Most were
below 12 NTU, with the highest recorded value of 114 NTU on August 21, 2007. The significant fluctuations
observed between August 21, 2007, and January 30, 2008, were likely associated with weather events
such as rainfall and snowmelt, and the maximum value may not be representative of actual maximum
values based on visual observations during rainstorms (WCWCD staff input). At station 4950510, most
samples were collected from the surface, except for a few taken between 13 and 28 meters below the
surface in 1979 and 1991. No notable differences in turbidity were observed. With a below-surface intake
planned for the new WTP, turbidity levels are expected to remain relatively stable; however, the reservoir is
very susceptible to weather events and significant turbidity spikes are anticipated during the monsoon
season.

Figure 4. Turbidity Historical Sampling Data
TDS
TDS data for these stations is summarized in Figure 5. All TDS levels around Gunlock Reservoir between
1979 and 2019 were lower than Utah DEQ’s recommended limit for drinking water (500 mg/L). To ensure
reliable water quality data and the selection of appropriate pilot testing technologies, new TDS sampling in
Gunlock Reservoir is recommended due to the absence of data from 2019 to the present.

Figure 5. TDS Historical Sampling Data
TOC
TOC was only monitored by WCWCD from 2022 until present as summarized in Figure 6. Samples were
collected from the surface. TOC levels varied from 3.3 to 6.9 mg/L with an average of 4.3 mg/L. Since NOM
impacts process selection and is the major determinant of DBP concentrations, weekly sampling is
recommended for the selection of appropriate pilot testing technologies.

Corrosion Control Parameters- Alkalinity, Calcium, Chloride and Sulfate

Hazen and Sawyer
10619 South Jordan Gateway, Suite 130,
South Jordan, UT 84095
Alkalinity, calcium, chloride and sulfate are additional key parameters for corrosion control in the finished
water. Historical data is shown in Figures 7 to 10. The alkalinity levels were high (>120 mg/L), with most
values exceeding 156 mg/L. Elevated alkalinity acts as a pH buffer, making it more difficult to adjust the pH
for optimal coagulation. As a result, the treatment process may require increased coagulant dosing to
achieve the desired water quality.
RTW modeling was conducted, and the preliminary results indicate that some raw water with a pH below
7.5 exhibits corrosive properties. Since these finished water quality parameters are expected to be similar
to raw water values, it is recommended that monitoring of corrosion control related parameters including
pH, temperature and TDS, alkalinity, calcium, chloride and sulfate be conducted. The RTW model will be
utilized to assess the corrosive potential of the finished water obtained from pilot testing.

Primary Inorganic Contaminants
The Utah DEQ issued standards for 19 primary inorganic contaminants2, as detailed in Table 1. Historical
data for antimony, asbestos, beryllium, nickel, and thallium is not available, while data for the remaining
contaminants has been compiled in Table 1. With the exception of arsenic and a few unavailable/unknown
parameters, all other inorganic contaminants were found to be significantly below the regulatory limits set
by Utah DEQ.
Arsenic concentrations are shown in Figures 11 and 12, with the highest levels predominantly detected in
samples from the Santa Clara River downstream of Gunlock Reservoir. Pilot testing will assess various
coagulation methods to enhance arsenic removal. Data on pesticide/PCB/SOC contaminants and volatile
organic contaminants was not available but will be included in the new sampling plan for future monitoring.
Overall, the findings indicate that Gunlock Reservoir is a reliable raw water source for the WTP.

Some samples, including those for aluminum, copper, iron, and manganese, exceeded secondary limits,
as shown in Figures 13 to 18. The copper concentration data point of 20 ppm may be an outlier. Aluminum
can typically be removed through oxidation, coagulation and flocculation, while oxidation methods such as
prechlorination, ozone, or filtration may be necessary to address iron and manganese concerns.
Most inorganic contaminants were well below the regulatory limits established by the Utah DEQ. Chloride,
sulfate, and TDS levels are well below the recommended thresholds and are unlikely to cause consumer
complaints.

Other available Data -TP
Total Phosphorous (TP) historical sampling data is summarized in Figure 19. The 2004 TMDL1 summarized
available data from 1979 to 2001 for TP, average concentrations in May and June are above the pollution
indicator value of 0.025 mg/L but concentrations in August are below the pollution indicator value. Data was
not available for other months. More than 40 percent of recent samples have exceeded 0.025 mg/L, which
can lead to rapid algal growth and blooms.

Note: “UTAH DEQ RECOMMENDED POLUTION INDICATOR VALUE 0.025 MG/L” was obtained from 2004 TMDL.
Figure 19. Total Phosphorous Historical Sampling Data
Total dissolved phosphorus often constitutes a significant portion of the total phosphorus, highlighting
sources like septic systems and livestock, shown in Table 3. Trophic State Index (TSI) classifications for
Gunlock Reservoir, based on TP, Secchi Depth and chlorophyll-a data, are presented in Table 4. Historical
data shows that Gunlock Reservoir is classified as a combination of Oligotrophic, Mesotrophic, and
Eutrophic, with highly variable water quality. This range reflects nutrient levels that vary from low to high,
leading to corresponding variations in water quality and the potential for algae blooms. According to the
2024 Integrated Report on Water Quality prepared by Utah DEQ2, Gunlock Reservoir is identified as
impaired due to elevated total phosphorus concentrations.

Other available Data -TSS
Historical sampling data for TSS is summarized in Figure 20. As anticipated, TSS levels are higher in the
Santa Clara River both upstream and downstream of Gunlock Reservoir. The reservoir functions as a buffer
system, allowing TSS to settle and stabilize. Given that the intake for the new WTP is planned to be located
below the reservoir, TSS is not expected to impact raw water quality.

Other available Data - Algae Taxa
Gunlock Reservoir has experienced multiple algal blooms due to significant changes in nutrient levels over
time1. Phytoplankton samples were taken on August 27, 1997, July 27, 1999, July 7, 2002, and October 9,
2002. Algal blooms can occur year-round and exhibit considerable variation. For example, the algal biomass
included diatoms, flagellates, green and yellow-green algae, and blue-green algae. On August 27, 1997,
flagellates, particularly Pteromonas (46%), and diatoms, such as Fragilaria crotonensis (26%), made up
98% of the algal biomass. On July 27, 1999, diatoms dominated the biomass, comprising 93%. Data from
August 2002 revealed a higher presence of blue-green algae, with Microcystis Incerta being the dominant
species, although no blue-green algae were observed during the October 2002 sampling.
3. Sampling Plan
Pilot testing will span approximately 18 months to assess the impact of seasonal variations in raw water
quality on treatment performance. An annual sampling plan is provided in Appendix A to cover both primary
and secondary contaminants and evaluate the seasonal shift of water quality. Weekly sampling is
recommended for major water quality parameters. pH and temperature should be tested onsite immediately
after the water is sampled. The first round of sampling will be conducted to cover all major water quality
parameters, and the following sampling rounds will be adjusted to eliminate unnecessary parameters based
on the results.
Assuming all parameters will be tested all year round, total annual cost is estimated at approximately
$60,000 (Table 5). Some parameters will be adjusted based on the first-round results, so the total cost is
anticipated to be lower. General conditions and contingency are added to cover shipping, tax, etc.

Re: WSWTP Jar Testing Results – Round 1
1. Introduction
The Washington County Water Conservancy District (WCWCD) plans to construct a new surface water
treatment plant (10-15 MGD) within the next decade, using raw water from Gunlock Reservoir. The
historical water quality data and the new sampling plan indicate that conducting a bench test before a pilot
test is essential to assess the removal of Utah DEQ Primary and Secondary Inorganic Contaminants (such
as arsenic, iron, and manganese) as well as total organic carbon (TOC), which is a precursor for disinfection
by products (DBPs).
This technical memorandum presents bench-scale testing that compares the effectiveness of conventional
treatment and dissolved air flotation (DAF) in removing contaminants regulated by the Utah DEQ and
meets WCWCD’s treatment goals. Jar testing was conducted using water samples from Gunlock Reservoir,
three coagulant chemicals, and one polymer. The three coagulant chemicals were ALUM, ferric chloride,
and ferric sulfate, and the polymer used was Clarifloc C-358. Different dose concentrations of each
coagulant were used to determine the dose needed for effective treatment. Small doses of Polymer were
added in combination with the coagulant doses to look for impacts on coagulant demand. Jar testing is
highly influenced by raw water quality. Monthly jar tests are recommended to evaluate seasonal influences
from raw water.
2. Means and Methods
2.1 Zeta Titration
Prior to jar testing, a Zeta potential titration of each proposed coagulant was performed to identify the
optimal dosing concentration to neutralize the surface charges of particles in the raw water samples. A
detailed standard operating procedure (SOP) of the Zeta potential tests can be found in Appendix A.
To begin, 100 mL of raw water was added to a 200 mL beaker, and an initial pH and temperature reading
was taken. Next, using a stir bar and stir plate, the raw water was mixed at a rate high enough to create a
big swirl on the water surface to mimic flash mixing. Starting with ALUM, the dosing concentration was
increased in varying intervals until the Zeta potential measured 0 - 2 mV. After each dose, pH and
temperature were recorded, and samples were taken for zeta potential analysis after mixing for 30 seconds.
The water in the mixing beaker was discarded and replaced with new raw water. This process was repeated
with ferric chloride, ferric sulfate, and polymer.

2.2 Jar Test
Both conventional and DAF jar tests were conducted for varying coagulant concentrations and
combinations. Detailed SOPs for each type of test can be found in Appendix B. A photo of the jar assembly
used for the conventional ALUM testing is shown below in Figure 1. A photo of the DAF jar test assembly
for ALUM and polymer is shown below in Figure 2.

Gunlock Jar Testing Memo Page 3
All raw water samples used for the jar tests were collected in five 7-gallon carboys and filled to be
headspace-free, then agitated to homogenize the samples prior to jar addition. Each jar was filled with 2 L
of raw water, and each mixer was set at 300 rpm to simulate rapid mixing. Once the mixer reaches a steady
state, coagulant is rapidly added to the jars using a pipette. If polymer is used in the test, it is dosed
immediately after the coagulant during the rapid mixing phase.
For the conventional jar tests, the mixing schedule shown in Table 1 was used after chemical dosing was
completed. Once the settling/clarification step was completed, samples for TOC, arsenic, dissolved/total
iron, dissolved/total manganese, pH, temperature, UV254, and turbidity were collected from each jar.
Table 1 Conventional Jar Test Mixing Schedule
Step Speed (rpm) Duration (min)
Rapid Mix 300 0.5
Flocculation 1 60 10
Flocculation 2 20 10
Settling/Clarification 0 20
Prior to the DAF jar tests, the DAF saturator was filled with 2 L of DI water. The air saturation pressure
was then set and maintained at 85 psi. The same conventional mixing schedule was followed through the
Flocculation 2 step. After stopping mixing, a 10% recycle rate was initiated by purging 200 mL air saturated
DI from the DAF saturator into each jar. The dissolved air was then allowed to rise to the top of each jar
and dissipate for 5 minutes. Samples for the parameters mentioned in the conventional jar test procedure
were collected.

2.3 Jar Test Conditions - Round 1
The chosen jar test conditions for round 1 were based on the results of the Zeta titrations for each coagulant.
These results are discussed in the Results and Summary section. The chemical concentrations for Round 1
were included in Appendix B. Raw water quality for Round 1 is listed in Table 2. To monitor seasonal
effects on raw water, WCWCD will carry out monthly jar tests and evaluate their performance.

3. Results and Summary
The following subsections summarize the results of the Zeta titrations and the jar tests for each coagulant.
This set of results is for the first round of jar testing only and will be used to develop plans for future jar
tests.
3.1 Round 1 Jar test
3.1.1 Zeta Titration
Figure 3 below shows the Zeta titration results for each of the coagulants and polymer. Sample pH plotted
over coagulant dose is displayed in Appendix C. The results showed that a dose of 55 mg/L for ALUM
only, and 2 mg/L for the polymer only, were sufficient to neutralize the surface charge. The sample pH
decreased as the ALUM dose increased and remained constant as the polymer dose increased. Optimal Zeta
titrations were achieved for ferric chloride and ferric sulfate as doses of 100 mg/L and 20 mg/L,
respectively.

Figure 3: Zeta Titration Results

Gunlock Jar Testing Memo Page 6

The Zeta titration results primarily optimize the coagulant concentrations chosen for the following
conventional and DAF jar tests. The dosing concentration ranges for the ALUM only jar tests were skewed
slightly towards the optimal Zeta titration concentration of 55 mg/L. Similarly, the ferric chloride jar tests
had doses ranging from 50 to 100 mg/L to only examine doses closer to the optimal Zeta titration
concentration of 100 mg/L. Ferric sulfate at 20 mg/L dose was used.
The polymer, serving as a coagulant aid, boosts flocculation efficiency, leading to lower coagulant doses
in all jar tests where it was used with the examined coagulant. This can be seen in the ALUM + polymer
jar tests which had ALUM and polymer doses ranging from 15 to 30 mg/L, and 0.5 to 1 mg/L, respectively.
Both ranges fall below the optimal Zeta titration concentrations for ALUM and polymer.
3.1.2 ALUM Jar Tests
Figure 4 shows the TOC removal results of the conventional and DAF jar tests with varying ALUM doses.
The results for other parameters are shown in Appendix C. Additional images of the jars at different phases
of the mixing schedule can be found in Appendix D. The raw water in the first jar was used as the blank
test in both the conventional and DAF experiments. All the examined jars showed good flocculation
regardless of the chemical dose. Similar pH values were observed in both types of jars, and the pH trend
matched what was seen in the Zeta titration results for ALUM. Based on the turbidity results, the
conventional ALUM jars showed better clarification compared to the DAF ALUM jars. TOC removal was
similar in conventional and DAF jars; however, the low efficiency - attributed to the high ALUM
concentration - suggests that polymer supplementation is necessary. The conventional and DAF ALUM
jars showed similar post clarification concentrations for iron and manganese. The DAF jars exhibited higher
post-clarification arsenic concentrations compared to conventional jars, indicating possible arsenic

precipitation. However, arsenic removal via DAF is not a critical issue due to subsequent ozone treatment
and dual media filtration.
Figure 4 TOC Removal of Conventional and DAF ALUM Jar Tests

3.1.3 ALUM + Polymer Jar Tests
Figures 5 through 7 show pH, Turbidity, UV254, TOC and arsenic removal from the conventional and
DAF jar tests with varying ALUM and polymer doses. Images of the flocs in jars at different phases of the
mixing schedule can be found in Appendix D. All examined jars showed good flocculation even with the
reduced ALUM doses, which suggests that polymer is essential to improve coagulant and flocculation
efficiency. After clarification, lower pH values were seen in the DAF jars on average, and the pH values
remained relatively constant regardless of the ALUM + polymer dose. The conventional jars showed better
clarification than the DAF jars with all turbidity values measuring below 1.2 NTU. The TOC removal
ability of the DAF jars was slightly better than that of the conventional jars. Overall, the addition of polymer
improved TOC removal efficiency compared to ALUM jar tests without polymer. The DAF jars with 30
mg/L ALUM + 0.5 mg/L polymer and 20 mg/L ALUM + 1.0 mg/L polymer achieved approximately 27%
TOC removal. Higher arsenic removal was detected in the conventional jars (59% - 75%) compared to the
DAF jars (42% - 57%). Iron was not detected after clarification, and manganese was less than 5 µg/L in all
jars.

3.1.4 Ferric Chloride Jar Tests
Figure 8 shows the TOC removal results of the conventional and DAF jar tests done for varying ferric
chloride and polymer doses. The results for other parameters are shown in Appendix C. Additional images
of the jars at different phases of the mixing schedule can be found in Appendix D. Without polymer, the
50 mg/L and 100 mg/L ferric chloride jars did not show adequate flocculation. The addition of 0.5 mg/L of
polymer improved flocculation and allowed ferric chloride to be dosed at significantly reduced
concentrations (20 mg/L compared to 80 mg/L).
Lower pH and turbidity values were measured in conventional jars. In contrast to ALUM jars, where TOC
removal was higher in DAF jars, conventional ferric chloride jars exhibited better TOC removal. The
conventional 20 mg/L ferric chloride + 0.5 mg/L polymer jar achieved 30% TOC removal compared to
23% for its DAF counterpart. Lower arsenic was observed in the conventional ferric chloride jars, and the
arsenic levels were overall lower compared to those seen in the ALUM jar tests. This may be attributed to
iron compounds facilitating arsenic removal and promoting easier settling for clarification.
Additionally, much higher residual iron levels were detected in the DAF jars due to the settling mechanism.
The use of ferric chloride as the coagulant resulted in elevated manganese concentrations in both
conventional and DAF jars compared to the ALUM tests. Nevertheless, downstream ozone treatment and
dual media filtration would effectively remove both iron and manganese.

3.1.5 Ferric Sulfate Jar Tests
Figure 9 shows the TOC removal results of the conventional and DAF jar tests done for the varying ferric
sulfate and polymer doses. The results for other parameters are shown in Appendix C. Additional images
of the jars at different phases of the mixing schedule can be found in Appendix D. Both conventional and
DAF jar tests produced pin flocs, suggesting that higher ferric sulfate doses may be required to enhance
flocculation. While pin flocs ensure effective buoyancy and separation of the suspended particles and
contaminants in DAF jars, they did not increase contaminant removal due to insufficient doses. Similar
pH values were seen for both types of jars, and slightly higher TOC removal was seen in the conventional
jars. Like the ferric chloride jars, slightly higher arsenic removal was seen in the conventional jars and
total iron and manganese were higher compared to the ALUM jars.

4. Summary of Round 1 Jar Test Results
Round 1 jar test results suggested that the addition of 0.5 mg/L of polymer is essential as it reduces
coagulant demand while achieving better clarification and contaminant removal. Both the conventional and
DAF clarification methods produced good water quality, but the TOC removal efficiency of each method
was impacted by the type of coagulant and its concentration. Round 1 results showed that 30 mg/L ALUM
+ 0.5 mg/L polymer achieved 27% TOC removal in DAF jar tests. Notably, similar efficiency (23%) was
maintained at a lower ALUM dose (20 mg/L) when polymer was increased to 1 mg/L. While 40 mg/L ferric
chloride + 0.5 mg/L polymer combination delivered the highest TOC removal (33%) with good clarification
ability, ALUM was selected as the primary coagulant for future jar test due to its substantial cost advantage
($2/gallon vs. ferric chloride’s $11/gallon). Overall, DAF tests showed better TOC removal when ALUM
was used as the coagulant, whereas the conventional jars were better when ferric chloride or ferric sulfate
was chosen as the primary coagulant. TOC removal efficiency is summarized in Table 3 below. Monthly
conventional and DAF jar tests are recommended to evaluate the effect of raw water quality changes on
TOC removal with ALUM and polymer.

South Jordan, UT 84095
Zeta Titration SOP
Zeta potential measures the electrical potential difference between the surface of a particle and the
surrounding water, essentially measuring the net charge of colloidal particles in suspension. Zeta titration
is used to identify the isoelectric point (IEP), the pH level at which a surface carries no net charge. This is
particularly important in water treatment for analyzing surface charge and enhancing coagulation
processes.
A zeta potential of 0 mV signifies the ideal conditions for particle aggregation, such as coagulation and
flocculation. By offering real-time insights into the charge of suspended particles, zeta potential
optimization aids in precise coagulant dosing, enhances coagulation efficiency, lowers chemical expenses,
and improves overall water quality.

WSWTP Jar Testing Standard Operating Procedure

– Round 1

Hazen and Sawyer
10619 South Jordan Gateway, Suite 130,
South Jordan, UT 84095
WSWTP Jar Testing Standard Operating Procedure
1. BACKGROUND
The District plans to construct a new surface water treatment plant (10-15 MGD) within the next decade,
using raw water from Gunlock Reservoir and potentially the ENCE wells to supplement the local potable
water supply. The historical water quality data and the new sampling plan indicate that conducting a bench
test before a pilot test is essential to assess the removal of Utah DEQ Primary and Secondary Inorganic
Contaminants (such as arsenic, iron, and manganese) as well as TOC, which is a precursor for DBPs.
Jar testing is the process of adjusting treatment parameters and chemical doses individually and recording
effects on water quality to optimize the coagulation/flocculation (C/F) treatment process. Jar testing utilizes
source water specific to the individual treatment plant to mimic the operating conditions of that plant at the
given time. This standard operating procedure (SOP) includes conventional and dissolved air flotation
(DAF) jar testing.
Conventional jar testing begins with the addition of a coagulant (Ferric Sulfate or ALUM) during flash mixing,
followed by coagulation, flocculation, sedimentation, and filtration. Pre-oxidation could be evaluated to
enhance arsenic, iron, and manganese removal. Depending on the jar test results, a polymer may also be
added alongside the coagulant. A typical conventional jar test setup is shown in Figure 1.

Figure 1. Typical Conventional 6-Paddle Jar Test Setup

Hazen and Sawyer
10619 South Jordan Gateway, Suite 130,
South Jordan, UT 84095
DAF jar testing also starts with the addition of a coagulant during flash mixing, followed by coagulation and
flocculation, then the addition of air-saturated water in lieu of typical settling time. Unlike sedimentation,
DAF is a water clarification process that uses microbubbles to lift flocculated particles and suspended solids
to the surface. This method effectively removes slow-settling colloids, algae, metal hydroxides, fine
particulates, and hydrocarbons-making it a highly efficient alternative to traditional settling. A typical DAF
jar test setup is shown in Figure 2.

Figure 2. Typical DAF Jar Test Setup
Determining the optimal coagulant dosage and operating conditions (e.g., air saturation pressure and
recycling rate for DAF) is critical to improve the removal of TOC and other contaminants, which is essential
for designing the WTP. Once the C/F processes are optimized through jar testing, chemical dosing for the
pilot test should be flow-paced with the influent to hold the new treatment units in the optimal treatment
zone and should only change when it is adjusted by operators after new jar tests. During jar testing, pH,
UV254, and turbidity will be monitored onsite, while TOC, arsenic, dissolved/total iron, and dissolved/total
manganese levels will be analyzed by a third-party laboratory. The effect of settling time on TOC and
contaminant removal will be evaluated in the jar test. A suggested jar testing methodology and chemical
dosing scheme can be found in Table 1.

South Jordan, UT 84095

2. JAR TEST METHODOLOGY
2) Collect raw water with six 5-gallon carboys. Do not leave any headspace in the carboys.
3) Source coagulants (ALUM/Ferric) and polymer from bulk chemical tanks/drums at the Quail Creek
and West Dam water treatment plants. Dilute with distilled water to prepare stock solution. Prepare
a fresh coagulant stock solution on a weekly basis. If polymer is utilized for the testing, ensure it is
prepared or diluted every 24 hours. Moderate mixing should be used to avoid breaking down the
polymer chain.
4) Agitate a 5-gallon carboy to homogenize raw water, record raw water pH, temperature, turbidity
and UV254. Collect TOC, arsenic, dissolved/total iron, and dissolved/total manganese samples
(unfiltered) for a test at a third-party lab.
5) Rinse each jar with 50-100 mL of raw water twice and discard rinse water. Add 2 liters of
homogenized raw water into each jar.
6) Start testing apparatus at 300 rpm (full speed to simulate rapid mixing). Once the mixer reaches a
steady state, use a pipette to rapidly add the coagulant to each jar. When polymer is being used, it
should be dosed immediately after the coagulant during the flash mixing phase. This process
should not take more than 30 seconds to dose all jars. Given that only one or two pipettes are
available, use a pipette to accurately measure the chemical and transfer into a small beaker,
followed by a small syringe. Ensure some headspace is left in the syringe to allow the chemical to
be fully purged into the jar for accurate dosing.
7) Conventional Jar Test
After chemical dosing for all jars is complete, start the timer, and follow the mixing and sampling
schedule below:
a. Rapid Mix: 300 rpm, 30 seconds
b. Flocculation 1: 60 rpm, 10 minutes
c. Flocculation 2: 20 rpm, 10 minutes
d. Settling: 0 rpm for 20 minutes
e. Collect TOC, arsenic, dissolved/total iron, and dissolved/total manganese samples from
each jar after 20 minutes. When sampling, slowly open the sampling port, use the first 20
mL to rinse the port/tubing. Collect more samples with clean beakers/bottles to measure
pH, temperature, UV254 and turbidity onsite.

Hazen and Sawyer
10619 South Jordan Gateway, Suite 130,
South Jordan, UT 84095
8) DAF Jar Test
To prepare for the DAF jar test, fill the DAF saturator with 2 liters of DI water. Then, set the air
saturation pressure to 85 psi using an air compressor and maintain it at this level. Start the jar test
by following Step a) to g) with DAF jars. After chemical dosing for all jars is complete, start the
timer, and follow the mixing and sampling schedule below:
a. Rapid Mix: 300 rpm, 30 seconds
b. Flocculation 1: 60 rpm, 10 minutes
c. Flocculation 2: 20 rpm, 10 minutes
d. Initiate a 10% recycle rate by carefully decanting 200 mL (10% of the mixed liquor volume)
from the bottom of the jar while maintaining continuous mixing.
e. Stop mixing, sequentially open the “recycle” air saturated water distribution manifold to
purge 200 ml of air saturated water, pressurized to 85 psi into each jar.
f. Allow dissolved air to rise to the top of the jar and dissipate for 20 minutes.
g. Collect TOC, arsenic, dissolved/total iron, and dissolved/total manganese samples from
the sampling port on each jar. When sampling, slowly open the sampling port, use the first
20 mL to rinse the port/tubing. Collect more samples with clean beakers/bottles to measure
pH, temperature, UV254 and turbidity onsite.
9) It is recommended to take pictures of each jar to document C/F performance and record the visual
results regarding floc formation (i.e., size, color, abundance, floating ability in DAF).
10) Rinse jars with DI water for the next round of testing.
Tables 1 summarizes treatment scenarios to be tested in Round 1. Both doses will be adjusted according
to turbidity readings and visual appearance. The jar test record spreadsheet is shown in Appendix B.

Experimental guidance is provided in Figure 3 and 4, which outlines the steps to follow. To neutralize the
negative surface charges on non-settleable solids, a coagulant with charges opposite those of the
suspended solids is added to the water. This allows small, suspended particles to stick together, forming
microfloc that are not visible to the naked eye. Good coagulation requires high-energy flash-mixing to
disperse the coagulant and promote particle collisions. It's important to note that over-mixing does not affect
coagulation, but insufficient mixing will result in an incomplete step.

particles. Microfloc particles collide, causing them to bond and form larger flocs that remove TOC and other
contaminants. Polymer may be added to bridge, bind, and strengthen the floc, add weight, and increase
settling rate. It's essential to avoid tearing the floc apart, as it is difficult to reform them to their optimum size
and strength. If polymer is used, slow mixing during flocculation 1 and 2 may not efficiently disperse the
polymer into water, so polymer should be dosed at the 30-s flash mixing stage, if applicable. Mixing energy
(mixing speed), mixing time, and coagulant/flocculate doses will be optimized during the on-site jar test. A
jar test spreadsheet will be provided.

1. INTRODUCTION
Hazen and Sawyer (Hazen) has been requested to provide professional engineering services to perform
pilot-scale studies for the design of a new West Side Water Treatment Plant (WTP), which will be owned
and operated by the Washington County Water Conservancy District (WCWCD). The pilot system will
be set up at the current Gunlock WTP and tested using water sourced from Gunlock Reservoir. The
purpose of this Environmental Health and Safety Plan (EHASP) is to establish the health and safety
requirements, procedures and protocols necessary for protecting employees of Hazen and their sub-
consultants (herein referred to as project personnel) while working at the WTP. This EHASP includes the
assignment of responsibilities, minimum protection requirements, safe work practices, site air monitoring
programs and action levels, and emergency response procedures. This document is based upon available
historical information and the assessment of potential physical, chemical, and biological hazards
associated with the site and activities related to the planned investigation work.
A copy of this EHASP is available under control of the Hazen Project Manager. Compliance with the
provisions of this EHASP is required of all project personnel and their visitors who enter the site. This
EHASP will be periodically reviewed to ensure that it is current and accurately reflects new site data and
changes in work scope. The EHASP shall also be revised and updated as a result of audit findings and
accident investigations. Such changes are completed in the form of an addendum or overall revision to
this plan.
1.1 Statement of EHS Policy
Hazen and Sawyer is committed to providing a safe and healthful environment for all staff and visitors
and to minimizing impacts to the environment. The firm recognizes the benefit to employees of providing
instruction and training that ensures a safe working environment, and understands its obligation of setting
and enforcing standards of safety procedures.
It is the policy of Hazen to assure, to the maximum extent possible, that work facilities are free of
recognized hazards and unsafe conditions. It is the responsibility of all employees to conduct themselves
in an appropriate manner, to report any recognized hazards to an appropriate Hazen Manager and to avoid
placing themselves or others in a dangerous situation.
We consider safety of prime importance at Hazen, and we expect employees and persons associated with
the firm to fulfill their obligation to maintain a safe and healthful environment in which to work.
In the case of accidents that result in injury, regardless of how insignificant the injury may appear,
employees are required to immediately notify their supervisor and Hazen & Sawyer’s Human Resources
Department. All injuries or incidents, regardless of size or severity, will be reported immediately to the
client and the host facility.

vomit does not enter the lungs. Get medical attention immediately.

Washington County Water Conservancy District – West Side WTP Pilot Safety Plan Page 13 of 42
Sodium Bisulfite
Sodium bisulfite will be used to quench residual ozone at the end of ozone contact chamber. It is
considered a hazardous chemical by the OSHA Hazard Communication Standard (29 CFR 1910.1200). It
is a powder with a pungent odor. Appropriate gloves and eye protection shall be worn when handling the
chemical. The following measures should be taken if exposed:
· Inhalation – Remove to fresh air. If not breathing, give artificial respiration. Get medical
attention if symptoms occur.
· Skin Contact – Wash off immediately with plenty of water for at least 15 minutes. If skin
irritation persists, call a physician.
· Eye Contact – Rinse immediately with plenty of water for at least 15 minutes. If skin irritation
persists, call a physician.
· Ingestion – Do not induce vomiting. Get medical attention.
Sodium Hydroxide
Sodium hydroxide will be used for raw water and finished water pH adjustment. It is a clear colorless,
odorless liquid. Sodium hydroxide, also known as lye and caustic soda, causes severe burns of eyes, skin,
and mucous membranes, pneumonitis, and temporary loss of hair. Upon skin contact, it feels slippery due
to the process of saponification that occurs between it and natural skin oils.
The OSHA PEL and NIOSH REL are 2 mg/m3 (TWA).
Safety goggles, face shield, chemical-resistant gloves and protective clothing appropriate for the risk of
exposure shall be worn when working with sodium hydroxide.
Sodium Hypochlorite
Sodium hypochlorite will be used for ultrafiltration membrane clean-in-place cleaning. It is corrosive and
strongly irritating to the eyes, skin, and respiratory tract. Inhalation of fumes may cause pulmonary
edema. Ingestion may cause burns to the mouth and digestive tract, and abdominal distress, and may lead
to convulsions, coma and death. Currently OSHA does not list any Permissible Exposure Limits (PELs)
for Sodium Hypochlorite and there is no listing in the CDC-NIOSH Pocket Guide to Chemical Hazards
for Sodium Hypochlorite. As Chlorine OSHA exposure standards are PEL of 1 ppm and a Short-Term
Exposure Limit (STEL) of 3 ppm.
Tight fitting goggles, a face shield and nitrile gloves shall be worn when handling sodium hypochlorite.
Citric Acid
Citric acid will be used for ultrafiltration membrane clean-in-place cleaning. It is a weak organic acid
naturally found in citrus fruits and widely used in food, beverages, pharmaceuticals, cleaning agents, and

Washington County Water Conservancy District – West Side WTP Pilot Safety Plan Page 14 of 42
water treatment. Citric acid is generally considered low in toxicity but can still cause irritation upon
exposure. Direct contact with citric acid in solid or concentrated solution form may be mildly to
moderately corrosive, potentially causing skin irritation, redness, or chemical burns with prolonged
exposure. Eye contact can result in irritation, pain, and temporary corneal damage if not rinsed promptly.
While inhalation of citric acid dust or mist is not typically life-threatening, it may irritate the respiratory
tract, leading to coughing or shortness of breath—particularly in poorly ventilated areas. Ingestion of
large amounts may cause gastrointestinal discomfort, nausea, or vomiting, though serious poisoning is
rare.
Citric acid is not classified as a carcinogen by OSHA, IARC, or NTP. However, repeated or prolonged
skin exposure to concentrated solutions may lead to dermatitis.
Nitrile gloves are sufficient for handling solid citric acid or diluted solutions; for prolonged exposure to
concentrated solutions, consider neoprene or rubber gloves. Safety goggles should be worn when
handling powders or concentrated solutions; a face shield is recommended for splash-prone operations. A
NIOSH-approved N95 dust mask is advised when generating airborne dust.
Other Chemicals
The list of chemicals described in Section 3 is not exhaustive and other chemicals may be encountered
during the performance of the work associated with the pilot-scale testing. For any chemicals not
described in this document, personnel shall compile, review, and follow recommendations described by
Safety Data Sheets and other chemical safety documentation. Questions on the proper use or required PPE
should be directed to the Project Manager or Task Lead.
3.4 Physical Hazards
Slips & Trips
Slips and trips on construction sites are usually the result of poor housekeeping practices, poorly
maintained walkways, and the selection of inappropriate footwear for the walking surface or weather
conditions. To minimize slip, trip and fall risks, project personnel shall adhere to the following:
· Personnel shall maintain good housekeeping practices during and at the conclusion of tasks.
Project personnel shall stay out of areas that are cluttered or have loose debris.
· Tools and materials shall not be left on work surfaces after completion of the task at hand.
· Wear footwear appropriate to work.
· Avoid walking in areas which are wet or appear to be slippery. Walk around the area in
question.
· Ensure that ladders and stairs are secure and that stair tread surfaces provide adequate traction
to prevent slipping prior to climbing.

Washington County Water Conservancy District – West Side WTP Pilot Safety Plan Page 15 of 42
· Avoid talking on cell phones, texting, or emailing while walking.
· Personnel shall not run on the site.
Vehicular Traffic
Project personnel shall coordinate with onsite construction contractors as necessary and use devices such
as barricades and/or traffic cones in areas exposed to heavy equipment. Should project personnel need to
perform any activities near roadways, traffic control devices such as barricades and/or traffic cones shall
be used. In areas where vehicular speeds have the potential to reach 45 mph or greater, ANSI Class III
high visibility outerwear must be worn. Personnel shall avoid walking or standing in the blind spots of
idling vehicles.
Overhead Hazards
Project personnel will, at all times, stay well away from overhead loads. During work conducted on
elevated surfaces (scaffolding, ladders) or proximate to floor openings, material handling hazards may
occur which affect personnel working below these elevated surfaces. Project personnel shall avoid
working below or in close proximity to these surfaces while they are in use.
Onsite Construction
There may be some exposure to hazards due to ongoing construction work such as being struck by or
stuck against something, being caught by or in between something, falling objects and other overhead
hazards. Project personnel shall:
· Note construction activities that may be present. Avoid construction areas whenever possible.
· If personnel need to enter active construction areas, they should wear a hard hat and standard
PPE at all times, including reflective traffic vests. Have hearing protection available.
· Look ahead & face the direction you are moving.
· Be aware of your surroundings and heavy equipment in construction areas (i.e., backhoes,
cranes).
· Stay clear when a hoist is being used and never stand under a load or boom with a suspended
load.
· At no time should any body part be allowed to be placed under a raised load.
· Obey flagman or signal person(s).
· Remain a safe distance to avoid being struck by machinery.
· Observe and obey designated controlled access zones (e.g., roped off, barricaded, etc.).

Washington County Water Conservancy District – West Side WTP Pilot Safety Plan Page 16 of 42
Noise
Exposure to noise above the OSHA action level can cause temporary impairment of hearing; prolonged
and repeated exposure can cause permanent damage to hearing. The risk and severity of hearing loss
increases with the intensity and duration of exposure to noise. In addition to hearing damage, noise can
impair voice communication, thereby increasing the risk of accidents on-site.
· All project personnel shall distance themselves from the source of the noise, when possible.
· All project personnel must wear hearing protection, with a Noise Reduction Rating (NRR) of
at least 30, when noise levels exceed 85 dBA. As noise monitoring is not anticipated for this
project, the following rule of thumb can be used: if you need to raise your voice or have
difficulty understanding a normal tone of voice at a distance of approximately three feet,
hearing protection shall be used.
Heat Stress
Heat stress is probably one of the most common (and potentially serious) illnesses encountered at
construction and outdoor work sites. The potential for heat stress is dependent on a number of interacting
factors, including environmental conditions, clothing, workload, and the individual characteristics of the
worker. Personal protective equipment may severely reduce the body's normal ability to maintain
equilibrium (via evaporation, convection and radiation), and by its bulk and weight increases energy
expenditure. Due to these factors, regular heat stress monitoring and other preventive precautions are
vital.
Types and Symptoms of Heat Stress
High ambient temperature can result in health effects ranging from transient heat fatigue, physical
discomfort, reduced efficiency, personal illness, increased accident probability, etc., to serious illness or
death. Heat related conditions include:
Heat Rash
Heat rash can be caused by continuous exposure to hot and humid air and skin abrasion from sweat
soaked clothing. The condition is characterized by a localized red skin rash and reduced sweating. Aside
from being a nuisance, the ability to tolerate heat is reduced. To treat, keep skin hygienically clean, allow
it to dry thoroughly after periods of heavy sweating and change wet work clothing.
Heat Cramps
Heat cramps are caused by profuse perspiration with inadequate electrolytic fluid replacement. This often
robs the larger muscle groups (stomach and quadriceps) of blood which can cause painful muscle spasms
and pain in the extremities and abdomen. To treat, remove employee to a cool place and give sips of
water or an electrolytic drink. Watch for signs of heat exhaustion or stroke.

Washington County Water Conservancy District – West Side WTP Pilot Safety Plan Page 17 of 42
Heat Exhaustion
Heat exhaustion is a mild form of shock caused by increased stress on various organs to meet increased
demand to cool the body. Onset is gradual and symptoms should subside within one hour. Symptoms
include weak pulse; shallow breathing; pale, cool, moist skin; profuse sweating; dizziness; fatigue. To
treat, remove employee to a cool place and remove as much clothing as possible. Give sips of water or
electrolytic solution and fan the person continuously to remove heat by convection. Do not allow the
affected person to become chilled. First aid trained personnel shall closely evaluate the worker to ensure
symptoms are alleviated.
Heat Stroke
Heat stroke is the most severe form of heat stress; the body must be cooled immediately to prevent severe
injury and/or death. This is a medical emergency! Symptoms include red, hot, dry skin; body temperature
of 105° Fahrenheit or higher; no perspiration; nausea; dizziness and confusion; strong, rapid pulse. Since
heat stroke is a true medical emergency, transport the victim to a medical facility immediately. Prior to
transport, remove as much clothing as possible and wrap the victim in a sheet soaked with water. Fan
vigorously while transporting to help reduce body temperature. Apply cold packs, if available; place
under the arms, around the neck, or any other place where they can cool large surface blood vessels. If
transportation to a medical facility is delayed, reduce body temperature by immersing victim in a cool
water bath; however, be careful not to over-chill the victim once body temperature is reduced below 102o
F. If this is not possible, keep victim wrapped in a sheet and continuously douse with water.
Protective Measures
The implementation of preventative measures is the most effective way to limit the effects of heat-related
illnesses. During periods of high heat, adequate liquids must be provided to replace lost body fluids.
Replacement fluids can be a 0.1% salt-water solution, a commercial mix such as Gatorade, or a
combination of these with fresh water. The replacement fluid temperature should be kept cool, 50o F to
60o F, and should be placed close to the work area. Employees must be encouraged to drink more than the
amount required to satisfy thirst. Employees should also be encouraged to salt their foods more heavily
during hot times of the year.
All project personnel are to rest when any symptoms of heat stress are noticed. Rest breaks are to be taken
in a cool, shaded rest area.
All employees shall be informed of the importance of adequate rest and proper diet including the harmful
effects of excessive alcohol and caffeine consumption.
Training
Design personnel potentially exposed to heat stress conditions will be instructed on the contents of this
procedure. This training shall be conducted during new-to-job orientation, can be conducted during
routine safety meetings, and can be reviewed as a safety meeting/toolbox talk.

Washington County Water Conservancy District – West Side WTP Pilot Safety Plan Page 18 of 42
Adverse Weather Conditions
Electrical storms, tornado warnings, hurricanes, heavy rain and strong winds are examples of conditions
that would call for the discontinuation of work and evacuation from the site. Adverse weather procedures
are discussed in Section 8.6.
Broken Glass
Hach and other laboratory test kits use glass vials under vacuum. The ampules should only be broken
after they are fully submerged in a sample. Breaking the ampules in air can cause them to shatter.
Personnel must review the instructions and the appropriate Safety Data Sheets prior to using the test kits.
In the event of glass breaking, personnel shall treat chemical and/or biological hazards prior to attempting
to clean up glass. Broken glass must not be picked up by hand. Personnel shall use forceps or a dust pan
and broom to collect broken glass.
3.5 Biological Hazards
Project personnel working at field locations may be exposed to certain biological hazards during the
course of their activities onsite.
Bloodborne Pathogens
Bloodborne pathogens (BBP) are pathogenic microorganisms present in human blood that can cause
disease in humans. These pathogens include, but are not limited to, hepatitis B virus (HBV) and human
immunodeficiency virus (HIV).
Exposure may occur if an employee is injured and bleeding and another employee assists him/her and has
contact with their blood or other bodily fluids. Exposures by piercing mucous membranes or the skin
barrier through such events as needle sticks, human bites, broken glass, cuts, and abrasions may also
occur.
All Project personnel shall follow a Universal Precautions approach to infection control. According to the
concept of Universal Precautions, all human blood and certain human body fluids are treated as if known
to be infectious for HIV, HBV, and other bloodborne pathogens.
Any person’s clothing that becomes soiled with potential infectious fluids needs to be removed
immediately. Any clothing that is soiled with potentially infectious fluids is not to be taken home for
cleaning. Should eye, mouth, other mucous membrane, non-intact skin, or parenteral contact with blood
or other potentially infectious materials occur, Project personnel shall report the incident to the Project
Manager.

Washington County Water Conservancy District – West Side WTP Pilot Safety Plan Page 19 of 42
Mosquitoes, Ticks & Insects
Project personnel may encounter mosquitoes, ticks and other insects throughout the site. The bite of an
infected mosquito can transmit West Nile virus to humans. In most cases, those infected have no
symptoms or experience mild illness such as a fever, headache and body aches before fully recovering. In
some individuals, particularly the elderly, West Nile virus can cause serious disease that affects brain
tissue. At its most serious, it can cause permanent neurological damage and can be fatal. Encephalitis
(inflammation of the brain) symptoms include the rapid onset of severe headache, high fever, stiff neck,
confusion, loss of consciousness (coma), and muscle weakness. Death may result in some cases. From
March to November, when mosquitoes are most active, the following precautions are recommended:
· Wear protective clothing, such as long pants, long-sleeved shirts, and socks.
· If outside during evening, nighttime and dawn hours, consider the use of an insect repellant
containing no more than 30% DEET (N, N-diethyl-methyl-meta-toluamide).
· USE DEET ACCORDING TO MANUFACTURER'S DIRECTIONS. DEET is effective for
approximately four hours. Avoid prolonged or excessive use of DEET. Use sparingly to cover
exposed skin and clothing.
· Wash all treated skin and clothing after returning indoors.
Ticks are small, ranging from the size of a comma up to about one quarter inch. They are sometimes
difficult to see. When embedded in the skin, they may look like a freckle.
Lyme disease is caused by a bacterium that may be transmitted by the bite of a tick. When an infected tick
bites, the bacterium is passed into the bloodstream of the host, where it multiplies. If detected early, Lyme
disease can be treated with antibiotics. Lyme disease typically occurs from May through October and is
often characterized by a slowly expanding red rash, which develops a few days to a few weeks after the
bite of an infected tick. The illness can be accompanied by flu-like symptoms, such as headache, stiff
neck, fever, muscle aches, chills dizziness, bone pain, and/or general malaise. At this stage, treatment by a
physician is usually effective; but if left alone, these early symptoms may disappear and more serious
problems may follow. The most common late symptom of the untreated disease is arthritis; other
problems include meningitis, and neurological, and cardiac abnormalities.
Standard field gear (work boots, socks, and light-colored coveralls) provides good protection against tick
bites, particularly if the joints are taped. However, even when wearing field gear, the following
precautions shall be taken when working in areas that might be infested with ticks:
· Wear long pants and long sleeved shirts that fit tightly at the ankles and wrists; tape cuffs if
necessary.
· Wear light colored clothing so ticks can be easily spotted.
· Tick repellents may be useful. Permethrin, the active ingredient found in the product
Permanone, kills ticks on contact. DEET may be used on the skin. Permethrin may only be
applied to clothes.

Washington County Water Conservancy District – West Side WTP Pilot Safety Plan Page 20 of 42
· Inspect clothing frequently.
· Inspect head and body thoroughly when you return from the field, particularly on your lower
legs and areas covered with hair.
· Remove any ticks by tugging with tweezers. Do not squeeze or crush the tick. DO NOT use
matches, a lit cigarette, nail polish, or any other type of chemical to "coax" the tick out.
· Be sure to remove all parts of the tick's body, and disinfect the area with alcohol or a similar
antiseptic after removal.
For several days to several weeks after removal of the tick, look for the signs of the onset of Lyme
disease, such as a rash that looks like a bulls-eye or an expanding red circle surrounding a light area,
frequently seen with a small welt in the center.
Bees and other stinging insects may also be present. Contact with stinging insects like bees, hornets and
wasps may result in project personnel experiencing adverse health effects that range from being mildly
uncomfortable to being life-threatening. Some of the factors related to stinging insects that increase the
degree of risk associated with accidental contact are as follows:
· Accidental contact with these insects is highly probable, especially during warm weather
conditions when the insects are most active.
· If a site worker accidentally disturbs a nest, the worker may be inflicted with multiple stings,
causing extreme pain and swelling which can leave the worker incapacitated and in need of
medical attention.
· Some people are hypersensitive to the toxins injected by a sting, and when stung, experience a
violent and immediate allergic reaction resulting in a life-threatening condition known as
anaphylactic shock. Anaphylactic shock manifests itself very rapidly and is characterized by
extreme swelling of the body, eyes, face, mouth and respiratory passages.
· The hypersensitivity needed to cause anaphylactic shock can, in some people, accumulate over
time and exposure. Therefore even if someone has been stung previously and not experienced
an allergic reaction, there is no guarantee that they will not have an allergic reaction if they are
stung again.
With these things in mind, and with the high probability of contact with stinging insects, all
project personnel will comply with the following safe work practices:
· If a worker knows that he/she is hypersensitive to bee, wasp, or hornet stings, he/she must
inform the FSCP of this condition prior to participation in site activities, and provide
instructions on appropriate care in the event of a sting. Project personnel with serious allergies
(i.e., likely to require hospitalization if stung a few times) should make the FSCP aware of
their condition.
· If stung, project personnel will immediately report to the FSCP to obtain first aid treatment
and to allow the FSCP to observe them for signs of allergic reaction.

Washington County Water Conservancy District – West Side WTP Pilot Safety Plan Page 21 of 42
· Project personnel with a known hypersensitivity to stinging insects will keep required
emergency medication on or near their person at all times.
Rodents/Vermin
Prevention of Exposure to Vermin/Rodents
All efforts shall be taken to ensure that the work area is routinely swept and that solid and/or liquid
wastes, refuse and garbage are removed in a timely manner to maintain sanitary conditions. Receptacles
used for solid or liquid waste or refuse shall be constructed so that they do not leak and may be
thoroughly cleaned and maintained in a sanitary condition. Such receptacles shall be equipped with solid
tight-fitting covers.
If rodents, signs of a rodent nest or rodent droppings in the work area are identified, project personnel
shall report the findings to the FSCP.
Hantavirus
Some rodents are infected with a type of Hantavirus that causes Hantavirus Pulmonary Syndrome (HPS).
In the United States, deer mice and the white-footed mouse in the Northeast are the rodents carrying
Hantaviruses that cause HPS. Common house mice do not carry Hantavirus.
These rodents shed the virus in their urine, droppings and saliva. The virus is mainly transmitted to people
when they breathe in air contaminated with the virus. This happens when fresh rodent urine, droppings, or
nesting material are stirred up.
There are several other ways rodents may spread Hantavirus to people:
· If a rodent with the virus bites you, the virus may be spread in this way, but this is very rare.
· Researchers believe that you may be able to get the virus if you touched something that had
been contaminated with rodent urine, droppings, or saliva, and then touched your nose or
mouth.
· Researchers also suspect that if virus-infected rodent urine, droppings or saliva contaminates
food that you eat, you could also become sick.
Early symptoms include fatigue, fever, and muscle aches, especially the large muscle groups – thighs,
hips, back, sometimes shoulders. These symptoms are universal. There may also be headaches, dizziness,
chills, and/or abdominal problems, such as nausea, vomiting, diarrhea and abdominal pain. About half of
all HPS patients experience these symptoms. Because there have been so few cases of HPS, it is not clear
what the incubation period is for HPS. It appears to be between one to five weeks after exposure before
symptoms appear. Late symptoms include shortness of breath, as the lungs fill with fluid.

Poisonous Plants and Plant Hazards
Though the primary work associated with this project is within an enclosed trailer, poison ivy and poison
oak may be present in parking and other exterior areas. Poison ivy thrives in all types of light and usually
grows in the form of a trailing vine; however, it can also grow as a bush and can attain heights of 10 feet
or more. Poison ivy has shiny, pointed leaves that grow in clusters of three; however some variations have
five leaflets. Poison oak resembles poison ivy except that the poison oak leaves are more rounded rather
than jagged like poison ivy, and the underside of poison oak leaves are covered with hair.
The skin reaction associated with contacting these plants is caused by the body's allergic reaction to
toxins contained in oils produced by the plant. Becoming contaminated with the oils does not require
contact with just the leaves. Contamination can be achieved through contact with other parts of the plant
such as the branches, stems or berries, or contact with contaminated items such as tools and clothing. The
allergic reaction associated with exposure to these plants will generally cause the following signs and
symptoms:
· Blistering at the site of contact, usually occurring within 12 to 48 hours after contact.
· Reddening, swelling, itching, and burning at the site of contact.
· Pain, if the reaction is severe.
· Conjunctivitis, asthma, and other allergic reactions if the person is extremely sensitive to the
poisonous plant toxin.
· If the rash is scratched, secondary infections can occur. The rash usually disappears in 1 to 2
weeks in cases of mild exposure and up to 3 weeks when exposure is severe.
The best treatment appears to be removal of the irritating oil before it has had time to cause inflammation.
This can be accomplished by immediately washing the affected area with a thick lather of laundry soap,
or a 1:1 mixture of alcohol and water. A visual site inspection and identification of the plants should be
completed prior to starting work so that all individuals are aware of the potential exposure. Preventive
measures, which can prove effective for most project personnel are:
· Avoid contact with any poisonous plants on site.
· Wash hands, face or other exposed areas at the beginning of each break period and at the end
of each workday.
· Avoid contact with, and wash on a daily basis, contaminated tools, equipment, and clothing.
· Barrier creams, detoxification/wash solutions and orally administered desensitization may
prove effective and should be tried to find the best preventive solution.
Keeping the skin covered as much as possible (i.e., long pants and long sleeved shirts) in areas where
these plants are known to exist will limit much of the potential exposure.

3.6 Communication Challenges
No cell signal is expected to be experienced while inside the pilot trailer. Working in an area with limited
communication can present safety challenges, especially in emergencies or when you need to
communicate with others. Here are some safety steps to follow when working in such conditions:
· Emergency Communication Plan - Before entering the trailer, establish an emergency
communication plan with a coworker or someone outside the trailer who has a cell signal.
Ensure they know your location, the duration of your work inside the trailer, and when to
expect you to check in. Agree on specific times for regular check-ins.
· Safety Equipment - Ensure you have all necessary safety equipment within the trailer, such as
a first-aid kit, fire extinguisher, and safety goggles. Having these items readily available can
be crucial in case of accidents or emergencies.
· Emergency Contact Information - Keep a list of emergency contact numbers and relevant
information inside the trailer. This should include local emergency services, your employer's
contact information, and any relevant medical contacts.
· Check the Weather Forecast - Before entering the trailer, check the weather forecast for the
area. Extreme weather conditions can pose additional risks, so it's essential to be prepared for
any changes.
· Safety Training - Ensure that you and your coworkers are trained in basic first aid and
emergency response procedures. Knowing what to do in various situations can be invaluable
in the absence of immediate communication.
· Signal Awareness Zones - Be aware of areas inside or around the trailer where you might
occasionally get a weak cell signal. These spots can be used for emergency calls if necessary.
· Emergency Supplies - Keep a small emergency supply kit within the trailer. This kit should
include essentials such as water, non-perishable food, a flashlight, extra batteries, and a
whistle.
· Stay Calm - In the event of an emergency, stay calm and follow your established emergency
plan. Panic can make a situation worse, so focus on your training and preparedness.
· Training and Drills - Regularly conduct safety drills and practice emergency scenarios with
your coworkers. This practice can help everyone stay prepared and respond effectively in real
emergencies.

4. JOB HAZARD ANALYSIS
Table 4-1 presents an overview of hazards and environmental concerns that project personnel may
encounter while performing pilot studies. Detailed discussions related to these hazards and control
measures are provided in Sections 3 and 6. Plant staff will contain any spills after treatment using spill
kits located in each pilot enclosure.
As the project progresses, changes in work scope and new hazards may be identified. Where changes
present significant new and high hazard activities, post-EHASP JHAs or EHASP addenda (for significant
changes in the work) will be developed.

6. STANDARD OPERATING PROCEDURE, ENGINEERING
CONTROLS AND SAFE WORK PRACTICES
6.1 Site Rules/Prohibitions
The following site rules/prohibitions provide basic safe work practices that are used during the execution
of all field activities:
· Contact with surfaces/materials either suspected or known to be contaminated is avoided.
· Smoking is a potential fire hazard and as such is prohibited on all sites.
· Medicine and alcohol can increase the effects of exposure to toxic chemicals. Use of
prescribed drugs should be reviewed with an occupational physician. Alcoholic beverage and
illegal drug intake are strictly forbidden during site work activities.
· Personnel should practice unfamiliar operations prior to doing the actual procedures.
6.2 Lifting Procedures
Since lifting objects during this project may be unavoidable, project personnel will utilize the assistance
of others and utilize good lifting techniques for each lift, including:
· Project personnel will not lift more than 50 pounds without use of equipment or someone to
help with the lift.
· Try out the load first. If it is too bulky or heavy, get help. Other possibilities are using
mechanical devices (such as a crane or forklift) or handling aids (such as a dolly or cart).
· Keep the back straight and lift with the legs. If needed, wear a lifting belt.
· Lift slowly and carefully and do not jerk the load.
· Keep the load as close to the body as possible.
· Do not twist or turn the spine while lifting or carrying the load.
· Remember that lowering the load can be more stressful than lifting it.
6.3 Illumination
All activities at field locations are scheduled for the daylight hours. Should this schedule change,
adequate lighting shall be provided for all field activities.

Washington County Water Conservancy District – West Side WTP Pilot Safety Plan Page 35 of 42
6.4 Sanitation
Personal hygiene is essential when working around contaminated or potentially hazardous materials and
biological contamination. Project personnel must thoroughly wash their hands and faces upon leaving
worksites and the laboratory and before eating, drinking or any other practice that increases the
probability of hand-to-mouth transfer of contaminated material or chemicals.
Project personnel shall also practice good housekeeping techniques to keep work areas as sanitary as
possible.

Washington County Water Conservancy District – West Side WTP Pilot Safety Plan Page 36 of 42
7. PERSONAL PROTECTIVE EQUIPMENT
7.1 Introduction
The following Personal Protective Equipment (PPE) Plan describes PPE selection, use, limitations,
maintenance and storage, specifically with regard to the field and laboratory activities.
7.2 Field PPE Standards and Requirements
Only PPE that meets the following American National Standards Institute (ANSI) standards are to be
worn. When required, all workers will wear the following protection in accordance with this document:
· Protective Eyewear - ANSI Z87.1
· Head protection - ANSI Z89.1
· Protective toed footwear – ASTM F2412, ASTM F2413
· High visibility body wear – ANSI Class II
The task-specific JHA may specify additional required PPE for specific tasks.
All on-site workers must be properly fitted with PPE (i.e., protective clothing and respirators if required)
and must be trained in its use (i.e., donning and doffing).
Head Protection
The use of hard hats is required when working in active construction zones and when working near
elevated loads.
Eye Protection
Safety glasses with side shields are the minimum eye protection worn during laboratory work and can be
worn for hazards such as flying fragments, objects, large chips, particles, sand, dirt, etc. and when there is
no potential for chemical splash, small particulates or vapor exposure. In cases where project personnel
may be exposed to splashes or when small particulates are generated, safety goggles shall be worn. The
task specific JHAs will specify when safety goggles must be worn instead of safety glasses.
Persons requiring corrective lenses in eyeglasses, when required by this regulation to wear eye protection,
shall be protected by one of the following:
· Safety glasses whose protective lenses provide optical correction;
· Goggles or safety glasses that can be worn over corrective lenses without disturbing the
adjustment of the spectacles; or,

Washington County Water Conservancy District – West Side WTP Pilot Safety Plan Page 37 of 42
· Goggles that incorporate corrective lenses mounted behind the protective lenses. The use of
contact lenses should be avoided, when possible.
Hearing Protection
If noise levels above 85 dBA are encountered, project personnel shall wear hearing protection as
appropriate. A good way to estimate excessive noise is when people communicating with each other at a
distance of three feet must raise their voices to hear one another.
Hand Protection
Project personnel handling rough, sharp-edged, abrasive materials or whose work subjects the hand to
potential lacerations, punctures, burns, or bruises will use general-purpose work gloves.
Nitrile gloves are required when handling any materials that contain, or potentially contain, hazardous
substances. Nitrile gloves shall be worn if there is potential exposure to bloodborne pathogens.
Foot Protection
All project personnel assigned to this project will wear safety toed work boots with non-skid soles that
meet the most recent ANSI Z41.1 standards. Business visitors are required to wear fully enclosed leather
shoes and must only walk on well-maintained pathways. Rubber boots shall be worn when working in
wet conditions.
High Visibility PPE
The use of high visibility, Class 2 traffic safety vests, jackets or shirts is required at all times while in an
active construction zone or when near vehicular traffic. Although not expected, if project personnel will
be conducting activities near roadways, ANSI Class III high visibility outerwear must be worn in areas
where vehicular speeds have the potential to reach 45 mph or greater.
Respiratory Protection
Project personnel are not expected to be subjected to harmful concentrations of dusts, gases, fumes, mists
or toxic materials. Therefore, the need for respiratory protection is not currently anticipated. If the scope
of work or anticipated conditions change, this EHASP will be modified accordingly.

Washington County Water Conservancy District – West Side WTP Pilot Safety Plan Page 38 of 42

8.2 Site Wide Emergency and Evacuation Procedures
Unless a public official (fire or police) is on site during an emergency, the facility’s Emergency
Coordinator (EC) is the primary authority for directing operations under emergency conditions.
Notifications
Communication of a potential emergency to persons both inside the pilot trailer and on the facility
complex would occur verbally by the discoverer, on-duty EC, and/or coworkers.
The facility is equipped with fire alarms. The primary method of notifying personnel of an evacuation
will be word-of-mouth, or via the fire alarms. The primary method of communication during an
evacuation will be verbal by word-of-mouth or by cellular telephones.
Evacuations
Evacuation procedures may be necessary during one or more of the following emergencies:
· Uncontrollable fire
· Hazardous chemical release
· Acts of violence including bomb threats
· Severe storms
The three possible types of evacuations are Full Evacuation, Partial Evacuation and Shelter In-Place.
Full Evacuation

Washington County Water Conservancy District – West Side WTP Pilot Safety Plan Page 40 of 42
A full evacuation is considered when the entire facility is affected and the safety of facility and project
personnel is at risk. The primary assembly area shall be the primary evacuation gathering point as
determined by the EC.
Partial Evacuation
A partial evacuation is considered when a certain part of the facility or a certain part of the site is
evacuated based on the extent and severity of the emergency or after a full evacuation following a
headcount has been completed. The EC will determine what portions of the facility are to be evacuated
and what parts of the facility are considered “safe areas”.
Both primary and alternative gathering points may be utilized during a partial evacuation. Once at the
gathering place, the EC will conduct a head count of all persons under his/her supervision.
Shelter-in Place
Shelter-in-place is a precaution aimed to keep personnel safe while remaining indoors. Shelter-in-place
means selecting a small interior room, with few or no windows and taking refuge there until the
hazardous event has passed.
· The need for shelter-in-place shall be determined by the EC.
· Facility supervisors will conduct a head count at the evacuation gathering point of all persons
under his/her supervision.
· All doors and windows to the outside should be closed and locked and as many internal doors
as possible should be closed.
· Any window coverings should be closed.
· Stay away from windows and doors that contain glass.
· For gas releases or spills requiring shelter-in-place, HVAC systems in sheltering areas away
from the release should be shut off until an “all clear” has been established by the EC.
Project Personnel Evacuation Procedures
If an evacuation is required, project personnel shall follow these procedures:
· Personnel will proceed to the evacuation gathering points.
· No short cuts shall be taken when going to an evacuation gathering point.
· Avoid areas affected by the emergency even if it takes longer to reach the evacuation
gathering point.
· Do not block entry gates at the evacuation gathering points.

Washington County Water Conservancy District – West Side WTP Pilot Safety Plan Page 41 of 42
· It is mandatory that you report your presence to a head count coordinator immediately upon
arrival to an evacuation gathering point.
Supervisors will notify the EC the status of personnel assigned to them, including the following
information:
· All personnel accounted for at each location.
· Name(s) of missing personnel, if any and location of last seen at an approximate time.
The site evacuation map and muster points shall be reviewed with project personnel at the site prior to
entry.
Surrounding Area Evacuation
Emergency response agencies such as the local fire department will determine and conduct surrounding
area evacuation if it becomes necessary.
8.3 Medical Emergency
Emergency First Aid/Medical Treatment
The following sections provide details regarding actions to be taken during emergency first aid.
Personnel Injury
In the event of an injury, the following actions will be taken in their listed order:
1. First Aid/CPR-trained field personnel will advise the FSCP whether additional assistance by
paramedics or transportation to the hospital is immediately required.
2. In the event of a serious medical emergency, refer to Emergency Protocol (Section 9.1).
3. If injury is minor, emergency first aid will be applied on-site as deemed necessary.
4. After the emergency has been addressed, the incident must be reported immediately to the
Project Managers. An investigation shall identify contributing factors, root causes and
corrective and preventative actions. Corrective actions shall be developed such that they
address both the root cause(s) as well as any contributing factors identified.
Transportation to Emergency Facilities/Hospital
In the event of a medical incident, the victim can be transported to the following medical facility:
Intermountain St. George Regional Hospital
1380 E Medical Center Dr. St. George, UT 84790

8.4 Environmental Accident (Spread/Release of Contamination)
In the case of an environmental accident, notify the Project Manager.
Emergency contact phone numbers for project personnel are listed in Table 8-1.
8.5 Fires
Incipient Fires
Only incipient fires will be handled by employees who have been properly trained in fire extinguisher use
(including incipient fire response) and who are able to recognize the point when a fire is no longer
incipient. An incipient stage fire is one that has just started and is easily extinguished by one person with
one extinguisher and requires no special fire fighting gear or equipment. Typically, the fire has not
impeded any part of the building structure. Employee training for incipient level of fire response includes
reporting of fires, recognition of different types of fires, and use of portable fire extinguishers.
Fire Extinguishers
The pilot trailer is equipped with a wall mounted fire extinguisher type A B C. If there is the necessity to
use the fire extinguisher on-site, it shall be replaced immediately.
Fire Notification and Action
This information applies to all fires.
1. Determine if you are capable of safely extinguishing the incipient-stage fire, and should
attempt extinguishing it. Initiate the 911 Notification procedures, if needed.
2. Contact Task Lead and provide the following information:
o What is on fire?
o Where is the fire?
o Is the fire located near other combustible or toxic material?
o What is the severity of the fire?
o Are there any injuries?

Washington County Water Conservancy District – West Side WTP Pilot Safety Plan Page 43 of 42
3. Determine if an evacuation is needed.
4. Implement Evacuation Guidelines as needed.
8.6 Severe Weather
Upon threat of severe weather:
· Hurricane, tornado or severe thunderstorm watch: Be alert for weather conditions to worsen.
· Hurricane, tornado or severe thunderstorm warning:
o Move to an interior space. Relocate to the adjacent administrative building.
o Follow the direction of facility personnel.
8.7 Safety Equipment

Communication Program

HAZARD COMMUNICATION PROGRAM

PURPOSE AND SCOPE
This program has been prepared to meet the requirements of OSHA Standard 1910.1200, Hazard
Communication. It includes guidelines for the identification of hazardous chemicals, the preparation and
proper use of labels, administration of material safety data sheets (SDS), and employee training on
chemical hazards.

RESPONSIBILITIES
Project Management – Project Management is responsible for ensuring that employees working under
their direction receive adequate information on the chemicals and hazardous materials they may use
and/or be exposed to during the course of their employment. Project Management is responsible for
ensuring the Hazard Communication Program is implemented for the project under their direction.
Environmental Health & Safety Officer (EHSO) – EHSOs maintain chemical inventory and SDSs for
their assigned work location as well as coordinating SDS requests from employees.
Employees – Employees must actively participate in the hazard communication training program.
Employees are also responsible for asking for information on the chemicals and hazardous materials they
may need to use.

CHEMICAL INVENTORY
Each location shall maintain a chemical/hazardous material inventory for chemicals and hazardous
materials used or found at the location.

CONTAINER LABELING
Whenever possible, order chemicals and materials in containers sized conveniently for immediate use to
allow the manufacturer’s label to serve as the primary means of identification of the material and the
recommended precautions. Labels must remain legible and should not be marked or taped over. If the
original label becomes illegible for any reason, the container must be relabeled or the container and its
contents must be properly disposed of.
If materials must be transferred to a container other than the original, the receiving container must be
labeled to identify the contents. No unmarked containers of any size shall be left unattended.

SAFETY DATA SHEETS

Washington County Water Conservancy District – West Side WTP Pilot Safety Plan B-2
An SDS is a summary of safety, health, and environmental information associated with a specific
chemical or product. Each manufacturer or distributor is required to provide an SDS for materials they
manufacture or distribute.
Each location shall maintain a central file of SDSs for materials used at that location. As SDSs are
received, they should be forwarded to the EHSO at that site for inclusion in the SDS file. This file
provides the primary source of SDSs for chemicals and materials used at the location. The SDS file
should be periodically reviewed by the HSC or individual designated to maintain it to ensure SDSs are
present and that outdated SDSs are removed and updated.
Employees may request a copy of an SDS for any material they use or are potentially exposed to from
their EHSO or from Project Management. Employees should contact their EHSO or Project Management
with any questions regarding the hazards, storage, disposal or shipping of chemicals or potentially
hazardous materials.

ANNUAL HAZARD COMMUNICATION TRAINING
Each new employee will have a basic introduction on hazard communication provided during the new
employee orientation. The introduction includes:
· An overview of the OSHA Hazard Communication Standard
· Discussion on the location and availability of the Hazard Communication Program
· Instructions on how to access SDSs
· An explanation of how to read chemical labels and SDSs
Hazard Communication refresher training shall be provided annually thereafter. Hazard-specific training
is provided to those employees who may use or be exposed to chemicals or hazardous materials before
such use or exposure. Training is conducted during the course of specialized training such as a 40-hour
OSHA hazardous waste training program, hazardous materials awareness training, and/or during a Hazen
site pre-job briefing. This training includes:
· A review of chemicals and materials present or anticipated to be present
· Methods and techniques to detect the presence or release of a material in the work area
· Discussion on how to minimize or prevent an exposure
· An explanation of the proper use of personal protective equipment
