Identification of Relative Contaminant Discharge Leads to Lower Allocation
TIG Environmental assisted a potentially responsible party (PRP) in a complex Superfund sediment site involving five miles of urban and industrial waterway.
Using site-specific data, TIG Environmental calculated the mass per unit time discharge for contaminants of interest. We developed a quantitative method for evaluating the effects of the mass loading on sediments and investigated the potential nexus of the client's historical upland facilities to the site.
TIG Environmental’s analysis proved that polychlorinated biphenyl (PCB) releases from the client’s facilities were much lower than anticipated, resulting in a lower allocation.
