Director October 1, 2024 Michael Robertson Alpine Cove SSD 13377 Alpine Cove Dr Alpine, Utah 84004 Dear Mr. Robertson, Subject: RTCR Level 2 Assessment Alpine Cove SSD #25124 I would like to thank you for taking the time to meet with me on August 30, 2024, for a combined Sanitary Survey and Level 2 Assessments (L2) of your water system. DDW surveyor Russ Franklin was conducting the sanitary survey and I was addressing the additional L2 information. I did not complete the additional L2 Question set. Your willingness to accommodate this request is greatly appreciated. Observations: This site visit was a result of two Level 1 Assessments were triggered within a 12 month period. Multiple TC+ EC- samples at different locations throughout your distribution system. There were 15 TC+E- samples in October 2023. These were a direct result of several contractor damages to system pipelines that drained your tank. Thus a negative pressure was present in the distribution system and allowed contamination to enter. This matter was resolved and there were clean TC-E- samples. In July 2024 the routine sample at your residence (rear hose bib) was TC+E-. This rear hose bib could contribute to a TC+E- sample One of the repeat samples from the neighbors (Starkey?) house was TC+E-. This site was at a hose bib by the garage which is on rear of house, away from where the water service/meter is located. The house was not occupied and the interior water lines may have contained stagnant water. This could be the source for TC+E- bacteria result. Conclusions: 1. The dual purpose site visit did not discover any physical deficiencies at water system facilities. The two Cross Connection Control (C3) Program deficiencies were discussed and we will continue to provide resources to help you improve the written records (M006) and program implementation (M007). 2. We discussed the Revised Total Coliform ( RTCR) and Ground Water Rule (GWR) flow chart. Feel free to call if you have any questions on RTCR sampling protocols and procedure Recommendations: 1. Follow the BacT Flow chart I gave you. 2. We also reviewed the sampling techniques used. I suggest using chlorine type liquid in a spray bottle to disinfect the tap. The chlorine spray can be applied a couple times to get good contact time. The hose bibs should be run long enough for the water to change to cold, which indicates it is water from the main in the street. If at all possible avoid using these rear outside taps that may be affected by the house internal plumbing.
