The marsh sediment is contaminated with PCB, PAHs, Mercury, Chromium, Lead, Cadmium and Pesticides. The contaminants are entering the Marsh through CSOs and stormwater runoff discharges. But the loads of contaminants discharged in stormwater runoff are currently unknown. The NJMC has made the remediation and restoration of this ecosystem a high priority.
Evaluate the transport of contaminants via surface runoff into this highly industrialized ecosystem and develop an appropriate model that will estimate site-specific contaminant loads in runoff and for a set of priority contaminants of interest (NJTRWP).
Using existing digital maps and images, along with information of known runoff discharge locations and historical sediment chemical profiles of the Kearny Marsh, determine two locations: one from a representative industrial land use and one from a representative urban land use to collect runoff samples from a range of storm sizes. Automatic samplers and Trace Organic Platform Samplers (TOPS) in conjunction with USEPA approved analytical methods will be used to measure the following priority contaminants: Mercury, Chromium, Lead, Cadmium, PCB’s, Pesticides and PAH’s.
