Details: SUMMARY: Nov 2016 VOC detections for City Park Well (Entry Point C) DETAILS: On 3/17/17 I received an alert for detections of Ethylbenzene (0.0023 ppm), Toluene (0.0067 ppm), Dichloromethane (0.001 ppm), and Xylenes (0.0142 ppm) that were above the detection limit of 0.0005 ppm, but much less than 1/2 the Maximum Contaminant Level (MCL). The sampling was completed 11/22/16 and the cause of the detects was unknown. ACTION NEEDED: System was instructed to begin quarterly monitoring, with the first sampling to be completed prior to March 31, 2017 and the second sample to be taken between April 1st and June 30th 2017. Future monitoring is to be dictated by the results of these two subsequent sampling results.
