Details: SUMMARY: High DBP results DETAILS: They got two high results for TTHMs in the 4th quarter 2010, 0.0801 and 0.1009 ppm. I checked the Running annual average, and it is 0.0709 ppm, which is below the MCL of 0.08. They are in the construction phase of a new membrane treatment plant which will hopefully reduce their precursor levels. ACTION NEEDED: None. Continue sampling quarterly at 2 sites.
