National Drinking Water Database
New Jersey
627 systems serving 8,619,862 people
This drinking water quality report shows results of tests conducted by water utilities in New Jersey, provided to the Environmental Working Group (EWG) by the New Jersey Department of Environmental Protection. It is part of EWG's national database that includes 47,667 drinking water utilities and 20 million test results from 45 states and the District of Columbia. Water utilities nationwide detected more than 300 pollutants between 2004 and 2009. More than half of these chemicals are unregulated, legal in any amount. Despite this widespread contamination, the federal government invests few resources in protecting rivers, reservoirs, and groundwater from pollution in the first place. The information below summarizes drinking water quality for this state.
