A remedial investigation and feasibility study for the Brick Township Landfill was completed twice. The first study was done with Ebasco Services Incorporated in April 1987. The second report was completed by Birdsall Engineering, Inc. During the remedial investigation information was collected to characterize the nature and extent of contamination at a site. The information collected aids in the development of remedial alternatives to address potential threats identified during the investigation. From the data collected from this investigation and the prior one done by Ebasco of the landfill and groundwater certain conclusions were made (Birdsall engineering, inc., 2008).
Furthermore, the conclusions made by the remedial investigation found that the landfill is the source of contamination resulting the release of various contaminants into the subsurface and groundwater. The groundwater contamination was limited to the water table aquifer and Cohansey Formation with contamination not impacting the underlying Kirkwood Formation as of yet. The groundwater contamination plume has largely been delineated and only large volume irrigation wells are permitted to continue withdrawing water. When the statistical analysis was done of the groundwater quality it showed that the contamination levels were decreasing for some but not all contaminants (Birdsall engineering inc., 2008).
