A harmful algal bloom (HAB) is an algal bloom that can be dangerous to people, animals or the ecology. Some, but not all, HABs produce chemicals that can be toxic to humans and animals if ingested, inhaled, or if contacted by skin or mucous membranes. These toxins can also accumulate in fish and shellfish which can cause illness when either are consumed. HABs can occur in both the freshwater and marine water environments. For additional information on freshwater cyanobacterial HABs, please visit www.state.nj.us/dep/wms/bfbm/CyanoHABHome.html. For additional information on marine water-related HABs, please visit www.state.nj.us/dep/wms/bmw/phytoplankton.htm.
The Division of Water Monitoring and Standards provides water quality information to assess and manage New Jersey's water resources. This information is critical to knowing whether NJ’s waters are safe to swim in, aquatic life is healthy, fish and shellfish are safe to eat, and contributes information on whether water sources are safe to use for drinking water.

Collection of ambient water quality data (fresh, marine and ground water)
Development of water quality standards
Total Maximum Daily Loads (TMDLs)
Watershed-based restoration plans
Administration of nonpoint source pollution control projects to help restore impaired waters
The water quality monitoring data is used in the assessment and support of the Department’s responsibilities under:
Sections 303(d), 305(b) and 319(h) of the federal Clean Water Act
The federal Safe Drinking Water Act
The National Shellfish Sanitation Program
The USEPA’s BEACH Grant
