The NJDEP engaged Kleinfelder to help the agency understand and establish baseline water quality conditions within various watersheds, and to provide a basis for establishing total maximum daily loads (TMDLs) throughout three separate watersheds. The three watersheds studied were those associated with the Rancocas Creek, the Passaic River, and the Raritan River. These three watersheds comprise 25% of the area of the State of New Jersey.
The studies produced several outcomes. In the Rancocas Watershed, our conclusions led the NJDEP to choose not to proceed with a full TMDL study. For the Passaic River Basin, our efforts resulted in watershed-specific criteria for discrete locations, rather than broadly applied criteria throughout the basin. The Raritan River Basin TMDL study included several technical innovations, including a novel pollutant loading model.
