Raritan Pathogens Results 9.14.2023
by LRWP Outreach Monitoring Coordinator Jocelyn Palomino
The Lower Raritan Watershed Partnership and Rutgers Cooperative Extension of Middlesex County run a volunteer pathogens monitoring program from May to September every summer along the Raritan River. We collect water quality samples at non-bathing public access beach sites, provide our samples to the Interstate Environmental Commission for analysis in their laboratory, and report the results to the public on Friday afternoons.
Once again, our water quality samples taken on September 14, 2023 show Enterococcus bacteria levels exceed the EPA federal water quality standard at only one of our sites this week. Problem sites are indicated by red frowns on the map and chart which includes our most upstream site for the 5th week in a row: Riverside Park (Piscataway). Green smiles on the chart and map indicate sites with bacteria levels safe for recreation and include: Rutgers Boathouse (New Brunswick), Edison Boat Basin (Edison), Ken Buchanan Waterfront Park (Sayreville), South Amboy Waterfront Park (South Amboy), and 2nd Street Park (Perth Amboy).
Enterococcus and Fecal Coliform levels are used as indicators for the possible presence of disease-causing bacteria in recreational waters. Such pathogens may pose health risks to people fishing and swimming in a water body. Possible sources of bacteria include Combined Sewer Overflows (CSOs), improperly functioning wastewater treatment plants, leaking septic systems, and stormwater run off.
Our goal in reporting these results is to give area residents an understanding of potential health risks related to primary contact (touching) the water during water based recreation. Always remember to wash thoroughly after enjoying your weekend activities on the Raritan!

As always, thanks to our team of volunteers who came out this Thursday: Frank Dahl, Genevieve Ehasz, Piash Ahamed, and board president Heather Fenyk!
