The Cinnamon Creek Rec Area water system is a public water system and thus subject to the Administrative Rules for Public Drinking Water Systems. The Division has determined that, based on recent water quality samples, both Spring #2 (Upper) (WS002) and Spring #1 (Lower) (WS001) are low-quality ground water sources that do not reliably meet bacteriological standards. Cinnamon Creek Rec Area is now subject to requirement to provide continuous primary and secondary disinfection at Spring #2 (Upper) (WS002) and continuous secondary disinfection at Spring #1 (Lower) (WS001) and meet the following requirements: ●Submit documentation for Spring #2 (Upper) (WS002) demonstrating a disinfection CT (CT = Concentration × Contact Time) that achieves 4-log inactivation for virus through disinfection or apply for plan approval and obtain an operating permit for modifications to your chlorination facility that achieves 4-log inactivation for virus. ●Provide continuous disinfection and demonstrate compliance with primary and secondary disinfection requirements through ongoing monitoring and reporting using a Division-approved template. ●Continue monthly source assessment bacteriological monitoring of the Spring #1 (Lower) (WS001) and Spring #2 (Upper) (WS002) for assessment purposes. You must notify the Division in writing, within 30 days of the date of this letter, what action will be taken to address the low water quality at this water source.This correspondence should be addressed to the Vulnerable Source Assessment Team at EQDWVSA@utah.gov. If these steps are not completed within 30 days from the date of this letter the Division may need to follow up with formal enforcement actions. Department of Environmental Quality Kimberly D. Shelley Executive Director DIVISION OF DRINKING WATER Nathan Lunstad, P.E. Director State of Utah SPENCER J. COX Gove rnor DEIDRE HENDERSON Lieutenant Governor Andrew Clark Beecher Page 2 of 5 January 31, 2024 If you cannot complete the above steps within 30 days, the Division encourages you to apply for a Corrective Action Plan (CAP). The purpose of a CAP is to establish terms, conditions, and timelines for a water system to come into compliance with the significant deficiencies. A CAP can be granted if there are no violations associated with the deficiencies. A system can request a temporary CAP extension at requestcap.utah.gov. Nothing in the Corrective Action Plan prohibits the Division from taking further enforcement actions if a system fails to comply with the requirements in the Corrective Action Plan. If you have further questions regarding a CAP, contact Brandi Smith at (385) 515-1650. Background On June 18, 2014, the Director issued an operating permit for the Cinnamon Creek water system’s waterline and improvements to the system's two chlorinators (Spring No 1 Hypchlorinator, TP001; and Upper Spring Chlorinator, TP002). Because of a pattern of coliform-positive samples at Upper Spring (WS002), a condition of the 2014 Operating Permit required monthly coliform monitoring of WS002. The System collected a total of 42 source coliform samples since that requirement. Of those 42 samples, 30 tested positive for coliform, and seven tested positive for Escherichia coli (E. coli). All samples during September and August 2023 tested positive for E. coli. Additionally, a Microscopic Particulate Analysis (MPA) test taken September 19, 2023 had a moderate risk, indicating some risk that Spring #2 (Upper) (WS002) is under the direct influence of surface water. Further sampling is required per the Division’s letter dated October 13, 2023. Finally, of the three samples taken at WS002, two came back total coliform positive. A detailed sample history is attached to this letter. Coliform Samples Taken From Upper Springs WS002 Since July 2014 Total Samples Taken Coliform Absent Coliform Positive Coliform and E. coli positive 45 8 30 7* *August and September 2023 Samples Coliform Samples Taken From Upper Springs WS002 Since July 2014 Total Samples Taken Coliform Absent Coliform Positive Coliform and E. coli positive 3 1 2*0 *August and September 2023 Coliform bacteria, including E. coli, indicate potential contamination in drinking water. Coliform bacteria are commonly found in the intestines of warm-blooded animals and suggest the possible presence of harmful pathogens. Consuming water contaminated with coliform bacteria, particularly E. coli, can result in various health issues, such as gastrointestinal problems, diarrhea, abdominal cramps, Andrew Clark Beecher Page 3 of 5 January 31, 2024 and nausea. In severe cases, it can lead to more serious conditions like kidney failure or hemolytic uremic syndrome (HUS), especially among vulnerable populations like the elderly, the young, and those with compromised immune systems. Disinfection processes, like chlorination, play a crucial role in protecting public health by removing harmful bacteria, including coliforms and E. coli, ensuring the safety of drinking water. The bacteriological results indicate that Spring #2 (Upper) (WS002) and Spring #1 (Lower) (WS001) sources are low-quality ground water sources that do not consistently meet standards of bacteriologic quality. Based on your sample history, Cinnamon Creek Rec Area is subject to requirements to provide continuous primary and secondary disinfection of the Spring #2 (Upper) (WS002) and may be subject to additional treatment requirements if further water quality sampling results indicate that the source is UDI. Additionally, Cinnamon Creek Rec Area is subject to requirements to provide continuous secondary disinfection of the Spring #1 (Lower) (WS001) and may be subject to additional treatment requirements if further water quality sampling results indicate that primary disinfection is required. Existing Chlorinators The Division does not have sufficient information on the existing chlorinators (Upper Spring Chlorinator, TP002 and Springs No 1 Hypochlorinator, TP001) to determine if they are designed to meet all requirements for primary disinfection. Please provide documentation that the following requirement is met within 120 days to avoid the addition of deficiency points for each chlorinator to Cinnamon Creek Rec Area Water Sytem’s IPS report: ●TD25 – Disinfection required, but disinfection is intermittent or not continuous due to lack of automatic switchover (SIG, 50 points) ●TD22 – Lacks backup power supply for required disinfection (SIG, 25 points) Required Actions The Cinnamon Creek Rec Area Water System is subject to requirements to install and operate Division-approved permanent primary disinfection for Spring #2 (Upper) (WS002) and the entire distribution system. The water system must also install and operate Division-approved permanent secondary disinfection for Spring #1 (Lower) (WS001). The system must comply with the primary and secondary disinfection requirements described in Addendum A. The water system must complete Division Plan Approval prior to construction of any disinfection facilities. The water system must also complete the bacteriological source assessment monitoring described in the “Additional Required Monitoring” section of this letter. Until the above actions are taken, the distribution system will be marked as unapproved, and 200 IPS points will be assessed for an unapproved distribution system. The Division considers Spring #2 (Upper) (WS002) an unapproved source until primary disinfection is installed and operational. If this chlorination facility does not provide adequate disinfection, 200 significant deficiency points will be assessed to Cinnamon Creek Rec Area, Andrew Clark Beecher Page 4 of 5 January 31, 2024 UTAH03105 for inadequate disinfection for a groundwater system required to disinfect. Community water systems with more than 150 IPS points will be rated as unapproved systems if actions are not taken to address the IPS points. The 200 IPS points assessed for an unapproved source puts Cinnamon Creek Rec Area above the threshold. Additionally, failure to correct the significant deficiency in a timely manner will result in the system being assessed a treatment technique violation in accordance with R309-215-16(4)(a) and 50 Improvement Priority System (IPS) points to the System’s IPS Report. Additional Required Monitoring Based on the determination that Spring #2 (Upper) (WS002) requires primary disinfection, the following monitoring is required: 1. Based on the E. Coli positive results, the Division suspects that Spring #2 (Upper) (WS002) may be under the direct influence of surface water (UDI) i. An initial MPA sample was collected from Spring #2 (Upper) (WS002) on September 13, 2023 and scored Moderate, indicating a moderate risk for being UDI. 1. Please note that the Division protocol requires two consecutive low-risk MPA samples for this source to be considered not UDI. This source may be classified as UDI if the results of the follow-up MPA samples indicate moderate or high risk. Ongoing source assessment monitoring may also be considered in this determination. The Division can re-evaluate this source at any time if there are circumstances that affect its susceptibility to surface water influence. For information about UDI and MPA sampling, see the attached UDI Definition and Possible Causes. ii. A moderate risk MPA test result, as obtained on September 13, 2023, requires: 1. further sampling, as described below in bacteriological source sampling under condition 2 below, 2. a follow up MPA sample taken during spring runoff in 2024. 2. Bacteriological Source Sampling a. This system is subject to take monthly Escherichia coli (E. coli) samples at Spring #1 (Lower) (WS001 and Spring #2 (Upper) (WS002) (assessment monitoring) during the operating period and shall continue for a minimum of 18 months.This schedule will begin April 2024. b. This sample is in addition to the monthly distribution system sample (DS001). Please label the source samples as WS001 and WS002 (for both the facility ID and sample point ID) on all laboratory forms. c. Please contact Sitara Federico for any positive samples that may occur at the sources at 385-515-1459 or sfederico@utah.gov. If any sample result comes back as E. coli positive, please contact the Division within 24 hours of being notified of the result. Please note that you must notify the Division in writing, within 30 days of the date of this letter, what action will be taken to address the low water quality at this water system. If Cinnamon Creek Rec Area does not take the steps outlined in this letter, the Director may need to follow up with formal enforcement actions to protect public health.This correspondence should be addressed to the Vulnerable Source Assessment Team at eqdwvsa@utah.gov.
