I.Introduction
The Drinking Water Program:An Overview
The EPA established the Public Water System Supervision PWSSProgram under the authority of
the 1974 Safe Drinking Water Act SDWA.Under the SDWA and the 1986 Amendments,EPA sets
national limits on contaminant levels in drinking water to ensure that the water is safe for human
consumption.These limits are known as Maximum Contaminant Levels MCLs).For some
regulations,EPA establishes treatment techniques instead of an MCL to control unacceptable levels
of contaminants in drinking water.The Agency also regulates how often public water systems
PWSs)monitor their water for contaminants and report the monitoring results to the states or EPA.
The larger the population served by a water system,the more frequent the monitoring and reporting
(M/R)requirements.Also,EPA requires PWSs to monitor for unregulated contaminants to provide
data for future regulatory development.Finally,EPA requires PWSs to notify the public when they
have violated these regulations.The 1996 Amendments to the SDWA require public notification to
include a clear and understandable explanation of the nature of the violation,its potential adverse
health eects,steps that the PWS is undertaking to correct the violation,and the possibility of
alternative water supplies during the violation.
The SDWA applies to the 50 states,the District of Columbia,Tribal Lands,Puerto Rico,the Virgin
Islands,American Samoa,Guam,the Commonwealth of the Northern Mariana Islands,and the
Republic of Palau.
The SDWA allows states and territories to seek EPA approval to administer their own PWSS
Programs.The authority to run a PWSS Program is called primacy.For a state to receive primacy,EPA
must determine that the state meets certain requirements laid out in the SDWA and the regulations,
including the adoption of drinking water regulations that are at least as stringent as the Federal
regulations and a demonstration that the state can enforce the program requirements.Of the 57
states and territories,all but Wyoming and the District of Columbia have primacy.The EPA Regional
Oices administer the PWSS Programs within these two jurisdictions.
The 1986 SDWA Amendments gave Native American Tribes the right to apply for and receive primacy.
To receive primacy,a Tribe must meet the same requirements as a state.To date,no Tribes have
been granted primacy.Currently,EPA administers PWSS Programs on all Native lands.
Annual State PWS Report
2023 ANNUAL COMPLIANCE REPORT •JUNE 30,2024 2 of 24
Primacy states to submit quarterly data to the federal Safe Drinking Water Information System
SDWIS/FED.Data includes PWS inventory statistics,the incidence of maximum contaminant level
violations MCLs),maximum residual disinfectant level violations,major monitoring and treatment
technique violations,lead action level exceedances,lead 90th percentile data,and the enforcement
actions taken against violators.The annual compliance report that states are required to submit to
EPA will provide a total annual representation of the number of violations for each of the four
categories listed in section 1414(c )3of the Safe Drinking Water Act reauthorization.These
categories are MCLs,treatment techniques,variances and exemptions,and significant monitoring
violations.The EPA Regional Oices report the information for Wyoming,the District of Columbia,
and all Tribal Lands.Regional oices also report Federal enforcement actions taken.EPA stores this
data in an automated Safe Drinking Water Information System SDWISdatabase.This report
contains data retrieved from the State version of the Safe Drinking Water Information System
SDWIS/STATE.
Generated on January 1,1998,the first annual report covered 1996.This report covers the calendar
year 2023.Subsequent reports will be created each July 1 for the previous calendar year.
Public Water System
The definition of a Public Water System PWSis a system that provides water via piping or other
constructed conveyances for human consumption to at least 15 service connections or serves an
average of at least 25 people for at least 60 days each year.In Utah,the Division of Drinking Water
DDWmaintains a rebuable presumption that any water system with at least eight service
connections has a population of 25 people based on the United States Census Bureau data.There
are three types of PWSs.A PWS can be a community (such as towns),non-transient
non-community (such as schools or factories),or transient non-community system (such as
restaurants,rest stops or parks).For this report,the acronym "PWS"means systems of all public
water systems unless specified in greater detail.
Maximum Contaminant Level
Under the Safe Drinking Water Act SDWA,the EPA sets national limits on contaminant levels in
drinking water to ensure that the water is safe for human consumption.These limits are known as
Maximum Contaminant Levels MCLs).Under the lead and copper rule,the national limits are called
"action levels"rather than MCLs.
Treatment Techniques
2023 ANNUAL COMPLIANCE REPORT •JUNE 30,2024 3 of 24
For some regulations,instead of an MCL,the EPA establishes treatment techniques T Ts)to control
unacceptable levels of certain contaminants.For example,treatment techniques have been created
for viruses,bacteria,disinfection byproduct precursors and turbidity.
Variances and Exemptions
A primacy state can grant a PWS a variance from a primary drinking water regulation if the
characteristics of the raw water sources reasonably available to the PWS do not allow the system to
meet the MCL.The system must agree to install the best available technology,treatment
techniques,or other means of limiting drinking water contamination that the Administrator finds are
available (taking costs into account),and the state must find that the variance will not result in an
unreasonable risk to public health to obtain a variance.At the time the variance is granted,the state
must prescribe a schedule (including increments of progress)that the PWS will follow to come into
future compliance with the MCL.Small systems (those serving 3,300 or fewer persons;or 10,000 or
fewer with the Administrator's approval)may receive a variance.Small systems qualify if they cannot
aord (as determined by application of the Administrator's aordability criteria)to comply with
certain MCLs (non-microbial),promulgated after January 1,1986,utilizing treatment,an alternative
source of water,or restructuring or consolidation.Small systems will be allowed three years to install
and operate EPA-approved small system variance technology.The variance shall be reviewed not
less than every five years to determine if the system remains eligible for the variance.
A primacy state can grant an exemption to relieve a PWS of its obligation temporarily to comply with
an MCL,treatment technique,or both if the system's noncompliance results from compelling factors
(which may include economic factors)and the system was in operation on the eective date of the
MCL or treatment technique requirement.A new PWS that was not in operation on the eective
date of the MCL or treatment technique requirement by that date may be granted an exemption
only if no reasonable alternative source of drinking water is available to the new system.Neither an
old nor a new PWS is eligible for an exemption if management or restructuring changes can be
reasonably made,resulting in compliance with the SDWA or improvement of water quality or if the
exemption will lead to an unreasonable risk to public health.The state will require the PWS to comply
with the MCL or treatment technique as expeditiously as practicable but not later than three years
after the otherwise applicable compliance date.
Monitoring
A PWS is required to monitor and verify that the levels of contaminants present in the water do not
exceed the MCL.A monitoring violation occurs if a PWS fails to have its water tested as required or
fails to report test results correctly to the primacy agency.
2023 ANNUAL COMPLIANCE REPORT •JUNE 30,2024 4 of 24
Significant Monitoring Violations
For this report,significant monitoring violations are defined as any major monitoring violation during
the report's calendar year.A major monitoring violation,with rare exceptions,such as turbidity
monitoring,occurs when no samples are taken,or no results are reported during a compliance
period.
Utah’s Improvement Priority System’s Rule IPS
Not reflected in this report is the Utah-specific Improvement Priority Systems Rule.The IPS rule is
codified in the Utah Administrative Code R309400.The IPS rule assigns numerical scores to public
water systems based on their compliance with various drinking water standards and operational
criteria.These scores help prioritize systems for regulatory aention and technical assistance.It
rates systems as Approved,Not Approved,Corrective Action,or Unrated.
II.The Calendar Year 2023 Statistics
Sources of Data
Before Utah implemented the Safe Drinking Water Information System SDWIS/STATE,the Annual
Compliance Report was based on data captured from the SDWIS/FED dataset frozen in April.The
State began using SDWIS/STATE production data to compile the Annual Compliance Report in June
2007 for the Calendar Year 2006 report.The 2023 report is from data provided by the U.S.EPA from
the SDWIS/FED April 2023 dataset and Utah's production SDWIS/STATE database compiled in June
2023.The data set contains all violations that remained open into any part of 2023.
Appendix A is a visual summary of Utah's water systems by system type.
Appendix B summarizes violations of all requirements during the calendar year 2023,the period
covered by the report.Violations that began before January 1,2023,and continued into 2023;
violations that ended during 2023;and violations at public water systems that operated for only part
of or permanently ceased operations during 2023 are included in Appendix A.
A list of water systems that were in violation during 2023 is available upon request.
2023 ANNUAL COMPLIANCE REPORT •JUNE 30,2024 5 of 24
Chemical and Radiological Contaminants (Organic,Inorganic,
Nitrogen Compounds,and Radionuclides)
The chemical contaminants monitored in drinking water include organic chemicals,inorganic
chemicals,and radiological parameters.Monitoring requirements for the various chemical
contaminants vary by system type and source,except that monitoring for nitrate,an inorganic
chemical contaminant,is required for all systems annually.
Systems are required to increase their monitoring to quarterly based on the following criteria:
1.For organic chemical contaminants,when the contaminant exceeds the trigger level
specified in the regulations;
2.for inorganic contaminants when the contaminant exceeds the MCL;and
3.for nitrates when the nitrate level exceeds half the MCL for community and non-transient
non-community water systems.
Organic Chemicals:Systems are initially required to sample annually for contaminants
in this classification.They can then move to three-or six-year monitoring based on
those results.A violation is issued for each individual analy te not sampled.
Pesticides:Initial monitoring for pesticides is quarterly.Systems can then move to
reduced monitoring or receive a waiver based on sample data and the susceptibility of
the source water.
Inorganic Chemicals:Surface water or Under the Direct Influence of Surface Water
UDIsystems are required to monitor annually for inorganics.Groundwater systems
are required to monitor every three years.If all samples are less than 75%of the MCL
for that contaminant,the system can reduce monitoring to every nine years.
Nitrate and Nitrite:All groundwater systems are required to monitor annually for
nitrate at each of their sources.Nitrite sampling occurs once every nine years.Surface
water systems monitor quarterly and can receive a reduction to annual sampling based
on sample results.
Arsenic:The frequency of arsenic monitoring is based on the initial sample results.
Systems treating for arsenic are required to test more frequently.
2023 ANNUAL COMPLIANCE REPORT •JUNE 30,2024 6 of 24
Radionuclides:Community water systems are required to submit radionuclide samples
as requested by the division during a four-year initial monitoring period under the
revised radionuclide rule.
The violations for chemical and radiological contaminant monitoring and reporting and MCLs
distributed as follows:

Total Coliform Rule
All public water systems are required to monitor for the presence of coliform bacteria.Acute
violations represent an immediate threat to public health.A non-acute MCL exceedance is
determined by the total coliform bacteria in the system.Either a single positive sample or 5.0%of
samples,depending on the population-based sampling requirements imposed on the system.
In all cases,systems were required to investigate,correct,and issue a public notification.Acute
violations require notification to the public within 24 hours of identifying the problem and may
include a boil or boled water order and increased monitoring.These violations resulted in system
notification and/or enforcement action.

Surface Water
Public water systems using Surface Water or sources classified as Under the Direct Influence of
Surface Water UDIare subject to the requirements of the Surface Water Treatment Rule.Drinking
water plants that cannot comply with the requirements for filtration of water supplies are evaluated
and provided with technical assistance to ascertain the cause of non-compliance.The problems
vary from poor operation to the need for new treatment plants.Where necessary,enforcement
action is taken to ensure that proper treatment techniques are used to provide safe water to
consumers.

bring the drinking water to within safe levels.Lead and Copper compliance is calculated using an
action level rather than an MCL.Evaluating the 90th percentile of samples collected determines
compliance with the action level.

General Information and Trends in Utah
Drinking Water Compliance
Public water systems are categorized by the types of populations they serve and their operating
period:
Community water system CWS –A PWS that serves at least 15 service connections used by
year-round residents or regularly serves at least 25 year-round residents (e.g.,homes,apartments,
and condominiums occupied year-round as primary residences).
Transient non-community water system TNCWS –A non-community PWS that does not
regularly serve at least 25 of the same persons over six months per year.A typical example is a
campground or a highway rest stop that has its own water source,such as a drinking water well.
Non-transient,non-community water system NTNCWS –A non-community PWS that regularly
serves at least 25 of the same persons over six months per year.A typical example of a
non-transient non-community water system is a school or an oice building that has its own water
source,such as a drinking water well.
