| Details: | While the wrong sample site was sampled for DBPs in December 2024, and it resulted in just over the MCL at 62 ppb for HAA5s, a similarly high result (62 ppb) occurred at the correct DBP sample site in April 2025. Also, there was a similarly high result in 2018 (62 ppb). Therefore, there is no need to re-consider the moving the required DBP sample site. As stated in the previous, December 2025, contact report, this is a purchasing water system that does not have control of the chlorination from the water seller/producer (i.e., Astoria). |
