Nutrient Pollution

Nutrient pollution: is the process where too many nutrients, mainly nitrogen and phosphorus, are added to bodies of water and can act like fertilizer, causing excessive growth of algae. Severe algal growth blocks light that is needed for plants, such as seagrasses, to grow.

Bill requires limits on nutrient pollution for Barnegat Bay

If bill S-2341 becomes law, the state Department of Environmental Protection would have one year to prepare a report on the impacts of excess nitrogen, phosphorus and sediment flowing into the bay and its tributary streams. Within two years, the department would need to develop pollution limits, called total maximum daily loads, to restore water quality in the bay.

The legislation is a tougher version of an earlier resolution, SR-85, from Environmental Committee Chairman Sen. Bob Smith, D-Middlesex, that only calls on DEP officials and their counterparts at the U.S. Environmental Protection Agency to consider imposing daily load limits on the bay.
