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 took place in August 2019 by Urbani Fisheries Inc. 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 was 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.
