Nutrient Related Research
The New Jersey Department of Environment Protection has recently developed a Nutrient Criteria Enhancement Plan, required under USEPA's National Nutrient Policy. This document explains the Department's approach to developing and enhancing the existing surface water quality standards, nutrient criteria and policies to protect designated uses of all New Jersey's surface waters, including saline waters (estuarine and marine). Nutrient criteria development requires an understanding of the causal relationships between nutrient over-enrichment, various response variables, and documented impacts on attainment of designated and existing uses of New Jersey waters. This Plan outlines the steps to support nutrient criteria development, including monitoring and data collection; research of causal relationships; selection of appropriate indicators of use impairment; development of new assessment methodologies; development of new/enhanced criteria; and promulgation of the new criteria through amendments to the SWQS.

The Office of Science was tasked with developing new data and models to support our own state-specific effects-based nutrient criteria. This ten year research effort resulted in the sampling of over a hundred wadeable streams throughout New Jersey, 50 lakes and various estuaries. These more recent studies build on research carried out by the Office of Science going back to the 1970s involving water quality analyses, biological indicator development, hydrology and hydrogeologic modeling, and monitoring of the atmospheric deposition of nutrients from air pollution. These studies and reports are listed in attached links for different waterbody types.
