| Details: | On 10/29/2024 I received an alert for a single TTHM resultDBP-98 TOTAL HALOACETIC ACIDS (HAA5) (2456) 0.0717 MG/L 10/22/2024Routine DIST-A Distribution System. I e-mailed Curtis Olson with Hildand Water on 10/30/2024 regarding the alert and let them know that although the individual result exceeded 0.080 mg/l, this did not result in an Operational Evaluation Level (OEL) or location running annual average (LRAA) maximum contaminant level (MCL) exceedance as these are based on calculations using multiple individual quarterly results for each sampling location. No further action was needed at this time other than to monitor TOC/disinfectant levels and look for ways to optimize treatment to minimize disinfection byproduct levels, which the system has already been working on. | ||
