| Details: | SUMMARY: HAA5 Alert for single result over the MCL - no LRAA or OEL exceedance DETAILS: I received an alert for a single HAA5 result of 0.0699 mg/l from the Merts sample site (2DBP-01) and a single HAA5 result of 0.0675 mg/l from the 1st and D sample site (2DBP-02). I calculated the 4th quarter 2015 Locational Running Annual Average (LRAA) to be 0.0531 mg/l for Merts and 0.0514 mg/l for 1st and D and the Operational Evaluation Level (OEL) to be 0.059825 for Merts and 0.056275 for 1st and D, which were all below the HAA5 MCL of 0.060 mg/l. System has been working to resolve high HAA5 levels. I sent an e-mail to Jim Hatcher and Eric Bufkin with the City making them aware of the results and letting them know that no further action was needed. ACTION NEEDED: System to continue working towards reduced HAA5 levels. No other specific action is needed due to these results, other than to account for them in the annual Consumer Confidence Report. | ||
