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.

In these studies, it is ideal to collect at least one year of pre-restoration data and at least three years of post-restoration data.

Threats and Recommendations

This site is located within a major stream restoration that will take place by Urbani Fisheries Inc in 2020. This site allows us to monitor the quality of the water and habitat within the restoration and see how they improve with time. This stream restoration is aimed at increasing fish and macroinvertebrate habitat and decreasing stream temperatures. Both of these goals will have positive impacts on the overall water quality of the system.

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.
