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 SB24 was found to be good in 2019, which means it was not biologically impaired. Though the HGMI scored high, the habitat scored sub-optimal. This site suffers from 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. There was also lack of diversity of habitat at this site, which impacted the overall habitat score. In systems like this, we must make an effort to preserve high water quality, while also mitigating the habitat issues.
