6 A: (MJB) The use of extraction wells specifically to prevent groundwater from 7 moving away from a site is, and has been a commonly employed technique for 8 approximately 40 years, including at EPA superfund sites, as well as many other 9 non-superfund sites. In its Report No. 2003-P-000006 dated March 27, 2003, 10 EPA concluded that: "Pumping contaminated groundwater from the subsurface and 11 treating the water to rid it of contamination has been a generally accepted means of 12 remediation in the Superfund program. In January 2002, EPA reported that although 13 the number of Records of Decision selecting the pump-and-treat remedy decreased 14 from 92 percent in 1986 to 30 percent in 1999, pump-and-treat remedies are still the 15 most common groundwater cleanup remedies used at National Priority List [NPL] | |||
