| Details: | SUMMARY: HAA5 Alert for single results - no OEL or MCL exceedance DETAILS: On 11/17/17 I received an alert for an HAA5 result of 0.0633 mg/l from the 1st and D sample location and 0.064 mg/l from the Merts sample location, both of which were sampled 11/15/17. Although the individual results were high, the locational running averages for both sites were 0.040 for the Merts location and 0.036 for the 1st and D location and both were below the OEL and the MCL. The results were discussed on-site during a survey conducted 11/17/17. A new, lower TOC source was in use, which is anticipated to improve DBP levels. ACTION NEEDED: No further actions are needed at this time. | ||
