This Regional Shopping Center lies in an area that is being considered for Superfund status because of its location relative to a regional groundwater contamination issue. The client has been designated as a potential Responsible Party (PRP). The site also lies near a major stream tributary and soil conditions are very rocky. The Reynolds Group was able to bring the client back into the good graces of the regulatory agency by negotiating a reasonable scope of work for additional site assessment. TRG also performed a detailed review of adjacent potential cases that highlighted the possibility of off-site contamination. The investigation including installing “semi-permanent” soil vapor probes to a depth greater than 150 feet below ground surface and sampling them. Based on the results of the sampling, TRG prepared an expert’s consulting report that detailed why the client should be considered at most a “de minimis” contributor to any regional groundwater issue. TRG noted that there is a neighboring large contributor to the contamination that seems to have caused most of the problems. TRG is currently working to minimize the client’s PRP liability and is working closely with legal counsel to craft strategies regarding coordinating work with the off-site PRP.
