HydroAnalysis has designed interception wells for capture and control of contaminated ground water at oil pipeline terminals in NJ, SC, and NC.  A ground-water streamline and capture zone model developed by HydroAnalysis was used to determine the location, pumping rates, and design of ground-water extraction wells.  Client: Major oil pipeline company through subcontracts with The Paulding Company.

 

Site Assessment, Gasoline Service Station, Wilmington, Massachusetts

 

HydroAnalysis was retained as a consultant to “trouble-shoot” a gasoline service station site investigation complicated by the presence of chlorinated organic chemicals.  Dr. Shanahan analyzed the available data, developed a conceptual model that attributed the chlorinated solvents to an off-site source, and designed a field sampling program utilizing drive-point sample technology to confirm the conceptual model.  The result was a successful demonstration to the Massachusetts Department of Environmental Protection that an off-site source was responsible for the solvent contamination.  Client: Major oil company through subcontract with dsEnvironmental, Inc.
