Details: SUMMARY: One high DBP sample DETAILS: Received an alert from this system. Their DBP max sample site had a result over the MCL for the 3rd quarter of 2010. They normally take 2 samples per quarter. The average of the two was 0.0824 ppm, which is just over the MCL. The running annual average from the previous quarters comes out to 0.0723 ppm, less than the MCL. The system is in the process of installing a membrane filter plant, which hopefully will remove some TOC and lower DBP levels. Otherwise, they may have trouble with Stage 2 as they seem to have one high site. ACTION NEEDED: none for now. Disinfection profile should have already been done.
 
Associated Alerts: CHEM4368 - 09/14/2010 - TOTAL TRIHALOMETHANES (TTHM)
