Ground Water Remediation <br /> iGround water is known to be affected at both Sites 1 and 2 Because the <br /> extent of affected ground water in both areas is very limited, a short- <br /> term ground water extraction program may effectively remove the <br /> constituents of concern <br /> Ground <br /> At Site #1, ground water will be extracted from MW-4 and MW-5 <br /> Approximately 3,000 gallons of water will be removed from MW-5, and <br /> 1,000 gallons of water will be removed from MW-4 Extracting from <br /> the two wells will result in improved capture of affected ground water <br /> over extraction from MW-5 alone The extracted ground water will be <br /> pumped directly to a moveable Baker tank The tank will be located in <br /> close proximity to the two wells (Figure 5-2) The estimated ground <br /> water extraction rate is approximately 2 gpm The ground water <br /> collected will be pumped from the moveable tank into a larger, open- <br /> top Baker tank <br /> The open-top tank will be located in close proximity to the sanitary <br /> sewer manhole located east of the 1325 West Weber building The <br /> moveable tank will then be relocated to Site #2 to receive extracted <br /> ground water from MW-1A Ground water will be extracted from <br /> MWAA only, because all other wells in this area are now non-detect <br />' for TPH and BTEX Approximately 4,000 gallons of water will be <br /> removed from MWAA Because MW-1A is partially screened in a <br /> zone of relatively low permeability soils, the estimated extraction rate <br /> is less than 2 gpm The extracted ground water will be pumped directly <br /> to a moveable Baker tank The extracted ground water from Site #2 <br /> will then be combined with the water from Site #1 to the open-top <br />' Baker tank <br /> Once the required amount of ground water has been extracted from the <br />' both sites, all ground water monitoring wells will be sampled to assess <br /> the effectiveness of the extraction process <br />' Cround W 'n <br /> As indicated above, once a sufficient volume of ground water has been <br /> removed from Sites 1 and 2, the monitoring wells at these saes will be <br /> sampled to measure the effectiveness of the extraction program All 10 <br /> wells will be analyzed for TPH as gasoline and diesel (EPA Method <br /> 8015-Modified) and for BTEX (EPA Method 602) If the ground water <br /> 5-8 <br />
