OBJECTIVES
Î To quantify the levels and loadings of the contaminants of concern in New York-New Jersey Harbor estuary. [NJTRWP Phase One & CARP]
Î To identify and track down significant sources of these contaminants. [NJTRWP Phases 2, 3 & 4 + NJTRWP Implementation Plan] COMPONENTSCOMPONENTS OFOF THETHE NJTRWPNJTRWP
Workplan and Sampling Methodology Development (1997-2000)
PHASE ONE (June 2000 - April 2004): • hydrodynamic surveys • ambient surface water quality sampling • POTW, CSO, and SWO sampling
PHASE TWO: focused sampling of selected Phase I areas (2002-2004) • Passaic River Minor Tributaries • Elizabeth River Minor Tributaries • Hackensack River Hg
PHASE THREE: trackdown activities other point and non-point sources, sediments
PHASE FOUR: CARP modeling activities

Circulation in the Newark Bay Complex • Responds to multiple influences in a complex event-driven manner • Identification of long-term average pattern is difficult
Classical gravitational circulation can be broken down • Low discharges from Passaic River • Persistent winds can produce “flow-through” flushing events

Most contaminated waterbodies: • Hackensack River – Hg • Passaic River – 2,3,7,8-TCDD (and total PCDD/F TEQ) • Elizabeth River – total PCBs (and potentially PAHs) • Rahway River – total PCBs, DDTs, chlordanes, dieldrin
Appear to be five “source areas” for PCDD/Fs, including • Passaic River-Newark Bay Complex • Elizabeth River and Rahway River
