Details: SUMMARY: March 2017 VOC detections at City Park Well (EP-C) DETAILS: On 4/19/17 I received an alert for detections of Ethylbenzene (0.002 ppm), Toluene (0.002 ppm), and Xylenes (0.0162 ppm) for some follow-up sampling completed 3/29/17 in response to detections from sampling completed 11/22/16 (see 3/17/17 contact report). Dichloromethane was non-detect. The results are improved from the 11/22/16 results and are still much less than 1/2 the MCL, but still warrant quarterly monitoring. ACTION NEEDED: System was instructed to continue quarterly monitoring, with the next sampling to be completed between April 1st and June 30th, 2017.
