| Details: | Reached out to Detroit's DRC about the treatment technique violation requiring a Tier 2 public notice found in the June monthly surface water report for membrane treatment. Gave them information on how to correctly fill out the monthly reporting forms for IFE turbidimeter, PDRmax and LRVambient. Waiting for them to send me a copy of the Tier 2 public notice that is required by August 9th. 7/29: Met with Detroit and their membrane contractors on how to find the correct values in their SCADA so they can properly fill out their monthly reports. Detroit sent in an amended report for June 2025. All turbidity readings are below 1 NTU. There was one day (June 5th) where the LRVambient was below 4.0 because of an issue with the DIT - daily integrity test. 9/5: violations for May and June have been returned to compliance and the system has a score of 0. Amended June report will be updated on the system's SWTR page. |
