Water Quality Data

Each June, Raritan Headwaters scientists and volunteers visit 72 stream sites in the North and South Branch Raritan Watershed Region (WMA8) of New Jersey to collect data on the health of our streams.  Data collected includes a sample of benthic macroinvertebrates (used to calculate the High Gradient Macroinvertebrate Index;HGMI score), an assessment of the habitat in and around the stream, and chemical conditions in the water.  Chemical parameters include dissolved oxygen, phosphate, chloride, specific conductance, nitrate, turbidity, pH, and temperature. The HGMI is used by the NJ Department of Environmental Protection (NJDEP) and the US Environmental Protection Agency (USEPA) to determine if the site is meeting state and national water quality standards under the Clean Water Act.

Threats and Recommendations

The HGMI at SP02  was found to be fair in 2019, which means it was biologically impaired. Because SP02 has been consistently impaired based on the HGMI for more than 2 years, it is part of our quarterly chemical monitoring program so that we can begin to identify and address the causes of impairment. Much like the HGMI, the habitat scored sub-optimal. This site suffers from heavy bank erosion, lack of bank vegetative protection, and insufficient riparian zone width.  Increasing the bank vegetative cover and widening the riparian zone will help to decrease the bank erosion  and increase bank stability at this site.

What Can You Do?

Many people take clean water for granted, but we know it takes vigilance and hard work to protect the water in our rivers, streams and homes.

And we can’t do it alone. We need your help to ensure that everyone within our reach has access to safe, clean water that is swimmable, fishable and, above all, drinkable.
