| Details: | SUMMARY: Stage 2 DBP monitoring frequency DETAILS: Notice arrived for Creswell to sample for DBPs in Q1 of 2016. The letter from DWS last summer said sample Aug, Nov. Why sample now? Quarterly sampling is required until the LRAA is half or less than the MCL for all locations and each DBP. The LRAA for TTHM at the Meadow Lane location is 0.0402 mg/L. Possibly that is the reason for the notice. However, this value is sufficient for a monitoring reduction. Told Mike to sample Monday (Aug, Nov, Feb, May sched). Wrote DMCE about LRAA. ACTION NEEDED: Recheck with DMCE to see if monitoring reduction is allowed. | ||
