The New Jersey Water Quality Networks

Science Center Objects

The water quality of New Jersey's water bodies is monitored by the USGS New Jersey Water Science Center to characterize waters, identify trends over time, identify emerging problems, determine whether pollution control programs are working, help direct pollution control efforts to where they are most needed, and respond to emergencies such as floods and spills.

All New Jersey data collected by the USGS are stored and made available to the Nation through the public NWISWeb portal which provide access to water-resources data collected at approximately 1.5 million sites in all 50 States. Annually, the USGS finalizes and publishes the daily data in a series of Annual Water Data Reports.
