| Details: | Failure to meet WQP in September An excursion occurred when the daily pH value measured at the entry point was below the minimum value ( 7.2) set by DWS. Unfortunately, no additional pH measurements were taken for the next 12 days after the excursion on 9/18. Each additional day without test results for pH and alkalinity counted as an additional excursion for a total of 13 excursions. Mark reported that the water system sent a notification letter to all members via mail on October 11, 2022. I received a copy of the letter and emailed it to DMCE. Next steps: - Collect two rounds of lead and copper in the distribution system. Round one must be collected between January 1 and June 30, 2023. Round two between July 1 and December 31, 2023. Lead and copper samples must be collected at the same 5 homes used in previous years for lead and copper sampling. - The operator was reminded to measure pH and alkalinity in the distribution system during the lead and copper sampling and also two weeks after each round of lead and copper sampling. I recommended sampling pH and alkalinity at least once every week, but never less than once every 14 days. |
