The Department bases this decision on the fact that a) the ground water at the site is hydraulically controlled by ground water recovery systems necessary for the protection of human health and the environment b) DuPont signed an Administrative Consent Order with the Department in which they committed to remediating the RCRA land disposal units at the site, c) DuPont is complying with their EPA Hazardous and Solid Waste Management Permit which requires constituents at the site. A Classification Exception Area (CEA) has the effect of suspending the designated uses (potable for the Class Quaternary Aquifer and Potomac Raritan Magothy Aquifer System beneath the site) and constituent standards in the indicated areas for the duration of this Permit. Upon expiration of this permit, the status of the CEA will be reevaluated. CEA One includes groundwater beneath Lots l,2,3,4, 5, of Block 301, Pennsville Township, Salem County to a depth of about 200 feet. Figure 2 shows the location of the two CEAs, The 2 CEAs were combined into one CEA July ?09, with Permit renewal. CEA for entire site.

Since groundwater quality data indicates excedance of contaminants above the Primary Drinking Since groundwater quality data indicates excedance of contaminants above the Primary Note Water Standards. and the designated uses of Class ll~A aquifer included potable use, the CEA Water Standards, and the designated uses of Class ll-A aquifer included potable use, the established for this site is also 3 Well restriction Area. The extent of Well Restriction shall established for this Site is also a Well restriction Area. The extent of Well Restriction shall oincide with the boundaries of the CEA coincide with the boundaries of the CEA Well Restrictions set within boundaries of the CEA Restrictions Well Restriction Boundries Double Case Wells: With the exception of monitoring wells installed into the first water bearing zone, any proposed well to be installed within the boundary shall Double Case Wells be double cased to an appropriate depth in order to prevent any vertical contaminant migration pathways. This depth is either into a confining layer or 50 feet below the vertical extent of the CEA. Evaluate Production Wells: Any proposed high capacity production wells in the immediate vicinity of the should be pre?evaluated to determine if pumping from these wells would draw a portion of the contaminant plume into the cone of capture of the production wells or alter the configuration of the contaminant plume. Sample Potable Wells: Any potable well to be installed within the footprint of the shall be sampled annually for the parameters of concern. The first sample shall be collected prior to using the well. if contamination is detected, contact your local Health Department. lf the contamination is above the Safe Drinking Water Standards, then the NJDEP Hot Line should be called. Treatment is required for any well that has contamination above the Safe Drinking Water Standards.
