MINUTES June 15, 2000 4 BOARD OF HEALTH public health risk because of those really low levels. There are no plans right now to do any more on-pond drilling. We are basically off the ponds for the foreseeable future, maybe forever, based on what our land-based drilling tells us in the next 6-12 weeks." "I want to talk about the bog system briefly. If you've been out to the bogs at all, you've seen the system that we have out there. It's designed to try to capture all the EDB that's upwelling into the Quashnet River. It's been somewhat successful, not 100% reduction in EDB, but we've been able to knock the levels down quite a bit. The main point is that the system that is there is now, and has been, showing no EDB leaving that upper bog system of the Quashnet River. It's not continuing to travel down the Quashnet River; we've cut off that flow. It's contained within the bog system. A lot of sampling locations have gone to non-detects. We still have levels of EDB in surface water there and we are still evaluating that system." "The last issue I have is on private well issues. We have a lot of private wells in the town of Mashpee, in these areas I've been talking about. The first area that has most recently come to light, which has to do with FS-1, is Ashumet Road off of Route 130. We became aware of some properties down here. There is actually one home that is inhabited at.the end of the street; it sits on top of the plume as it is presently depicted here. There is another house under construction right across the street. The one that is inhabited has a private well as it's only source of water. The one across the street has received a well drilling permit. We sampled that one resident and three other homes just outside the plume boundary and they were all non-detect for EDB and VOC's so no contamination found. Contamination in this area is very deep. We estimate almost 100 feet of clean water between where the plume would be expected to be and the well screen, on average. We shared all this information with the regulatory agencies and DPH and the agreement we have is that the home on top of the plume gets monthly testing and bottled water service which is in place. The other three homes will get semi-annual private well testing, twice a year, they are scheduled to be sampled this month and then again in September, and they are not getting bottled water. The one thing that remains is the final solution to try to eliminate that future potential risk because we know what it's like now but we don't know what it might be months or years from now. AFCEE is currently evaluating bringing municipal water in here." "The other area is John's Pond. There are a lot of homes and a lot of private wells still in use down here. All of the properties that were sampled in this area, dozens and dozens over the years have all met drinking water standards and we have found sporadic low, low detections of things like chloroform, that's very persistent. MTBE is becoming more common which is nothing to do with the base. We occasionally see some tolulene hits or PCE or TCE, but there are no patterns that would suggest that something is there or is a threat to these properties. They are in our semi-annual program and we do the testing free of charge to those areas." Mr. McQuaid expressed his concern over the FS-1 plume as it relates to the new homes on Ashumet Road. He was bothered that the Board of Health wasn't adequately notified of the threat of contamination in that area. He further stated that he would rather see a charcoal filtration system instead of providing bottled water and periodic testing. He also stated that the Board of Health needs more notification of these types of situations. Mr. Mike Minior stated that the IRP is committed to providing periodic updates and meetings regarding contamination and plumes and that is exactly what they were doing on this evening. Mr. Minior stated that they would take that request back and
