Since this is the first time that 1,4-Dioxane has been detected above the 2L Standard a 14-Day notification form and a table summarizing the detections in MW-2 is attached. The facility is already under assessment monitoring in response to detections of other volatile organic compounds (VOCs) at MW-2, MW-3, MW-3A, MW-6 and MW-8. The source of the VOCs is believed to have originated from a release from the unlined landfill with a transport mechanism of either leachate and/or landfill gas. The full Semi -Annual Monitoring Report for this Fall 2018 event is planned to be submitted soon and assessment monitoring will continue.
