Levels of algae-causing nutrients in the state’s waterways are seeing declines or are remaining at current levels, according to a U.S. Geological Survey (USGS) commissioned by the New Jersey Department of Environmental Protection (NJDEP) and the Delaware River Basin Commission. Common causes of excessive nutrients in waterways include discharge from wastewater treatment plants, fertilizer and animal waste runoff, and outdated or malfunctioning septic systems. According to the study, the improvement in water quality is due largely to the modernization of wastewater treatment plants and stepped up efforts by the state to better manage stormwater through its municipal stormwater permitting program.
