| Details: | DWS staff contacted the system regarding the 4th-quarter DBP results, noting that the TTHM sample collected on November 18 measured 0.0916 mg/L, exceeding the MCL. With the inclusion of the 4th-quarter data, both the HAA5 and TTHM OELs—as well as the LRAAs —remain below the MCLs. No additional corrective action is required at this time; however, the system should continue monitoring TOC and disinfectant levels and pursue opportunities to optimize treatment processes to further minimize DBP formation. | ||
