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

While this site is no longer being actively monitored, all streams could benefit from keeping an intact riparian buffer and improving green infrastructure in the surrounding municipalities.  This site is located within a stretch of the South Branch Raritan River that is  Trout maintenance, meaning that this stream is capable of supporting existing trout, but not of supporting reproductive populations. At sites like this, preservation is key.
