a • NENUTES May l , 1996 5 Bow of HEALTH Mr. Bacigalupi stated, "Last right they presented us with the draft plan for the clean-up."" "we would have had the first portion of Mashpee water going to the design today has it not been for a former Mashpee resident and Sandwich resident."' I made the motion to accept the SD-5 pump and treat system at Pahner Road using eleven wells pumping 350 gallons per minute which wiU achieve better than 90% capture ofthe plume before it even gets to Mashpee and the M.C.L. where the highest concentrations of pollutants are on SD-5.7' "The plan has a lot ofgood things about it." "Comments that they're not doing anything for Mashpee are bull because they are domng more for Mashpee then any other town." "All of the plumes that are affecting Mashpee ee are being looked ed at, treated or tested and actually are going to do something with it." "You can't say the same thug about Falmouth or Bourne." "FS-12 is ready to go to design the problem is they can't capture the whole plume because of design.913 "The SD-5 plume by South outer Road has the highest level of concentration of the pollutants which is over 200 .p.b.." "'The plume is not a contiguous plume above M.C.L. any more.'" '`There is two levels, one on the base and another are on Briarood." "what I'm pushing the base for is not'to let any more additional stuff' come in because if your start putting any clean water here, (shown to the Board), eventually your going to flush all the pollutants out and they have agreed.' `Their proposal right now is to install 14 extraction wells and 14 in ection wells pumping 350 gallon er m nute.17 ITh yare willing to install 1 of the system first, that's about 504,000 gallons a day they are gog to pump out."" "They are going to put it in just slightly down gradient from it so it doesn't affect any pond levels.' "'The nearest wetlands are the two ponds just north of Ashumet and the vernal pool that's there.V) "The one benefit with this and part of the problem we're having is that all of a sudden when t ey did the treating scenario'their computer model is shifting the plume to the left and there is no real reason for that and we think that's some sort of aberration of the model." Further discussion took place regarding the remediation processes proposed for the Briarwo od area. . Corn ost Screening,.Agreement - Mr. McQuaid relayed, "Rather than have Weston, & Sampson come down to verify Mr. I it laggi 's measurement I had Cape Islands Surveyor's go out and give us their estimate." "Cape & Islands estimate was 1510.64 cubic yards Mr. DiMaggio"s estimate was 1,350 cubic yards." "Mr. Dimaggio is well within range.'
