on at the MMR, They were before the board almost a year last October. It <br /> was an annual visit to fill the board in on the recent developments in <br /> where they were at the present time, He then turned the discussion over <br /> to Dave Full from the groundwater study office. He was going to give the <br /> board a quick run through. Then Mr. Doug Carson from the AFSC IRP <br /> program will come up to give them an over view of what they have been <br /> doing. <br /> Mr, David Hill introduced himself to the board as the remediation <br /> specialist with the impact area groundwater study at Camp Edwards. <br /> What he had as a prop was a map of the entire installation. Their program <br /> was focused on the northern 15,000 acres of the MMR,, which was known <br /> as Camp Edwards. The board was probably aware of the fact that they <br /> had been studying this area to evaluate the entire trailing to the aquifer. <br /> For the past sic years their efforts were primary focused on investigations <br /> over that time. They were now in a program where they were transitioning <br /> into a cleanup. The map outlines the primary areas of foots for both <br /> investigation and cleanup. He began with demolition area one site. Demo <br /> One is an area where over the years the National Guard conducted <br /> demolition training* That type of activity involved open detonation as a <br /> means for training the troops in how to use explosives properly and <br /> i safely, over the years a fair amount of explosives and repellant <br /> compounds have been distributed throughout the soil. They have <br /> identified a plume of groundwater contamination emanating from the <br /> source area and extends 8 to-9,000 feet to the southwest. The cleanup <br /> project that they were now embarking on is called "'Rapid Response <br /> Action."that they planned on doing there was to install a groundwater <br /> extraction treatment and re-injection system in a couple of areas within <br /> the plume. 'They.,.regulators right now for extraction wells along Frank <br /> Perkins Road and they were closing grievance in how to go about that. <br /> They were also looking at the source area,, which was about a 7,5-acre <br /> natural depression that was used extensively for demolition activities. <br /> IIs. Warden asked Mr. Hill where that was located. <br /> Mr, Full pointed out the source area on the map, which was at the far <br /> north of the base. <br /> FIs. Darden asked if the deepest part of the pond in the northerly <br /> direction, <br /> Mr, Hill responded that that pond was above the plume. The plume was <br /> about 501 below the water table at that point. He wasn't sure what the <br /> symmetry looks like to be honest with her. They ► ere not aware that <br /> there were contents spilling into the pond. They did however have some <br /> 6 <br />
