Yesterday was the last day of pathogens monitoring for 2020. Despite COVID-related challenges and the general difficulties of juggling an all volunteer program, we met EPA requirements for quality data and built a great data set. HUGE THANKS to our partners: Rutgers Cooperative Extension of Middlesex County and the Interstate Environmental Commission. And much gratitude to all our wonderful volunteer monitors! We couldn’t do it without you!
Below are our pathogens results for 11.5.2020, followed by field notes for the day.
The LRWP and Rutgers Cooperative Extension of Middlesex County monitor for Fecal Coliform and Enterococcus at six non-swimming public beach access sites along the Lower Raritan during the warmer summer months. Fecal Coliform and Enterococcus are indicators of disease-causing bacteria in our waterways.
The EPA recommends that a single Enterococcus sample be less than 110 Colony Forming Units (CFU)/100mL for primary contact. Enterococci levels are used as indicators of 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. Sources of bacteria include Combined Sewer Overflows (CSOs), improperly functioning wastewater treatment plants, stormwater runoff, leaking septic systems, animal carcasses, and runoff from manure storage areas. Enterococci levels are often high after heavy or consistent rainfall.
Field notes for November 5, 2020
Another foggy start to the morning. Both our Riverside Park (Piscataway) and New Brunswick Boat House sites were gorgeous under a shroud of mist.
The views from our monitoring site in Perth Amboy are dramatic. To the left you look out to Raritan Bay and sailboats and huge ships heading into New York Harbor. To the right you look upstream, at the mouth of the Raritan, where the new “River Draw” train bridge is under construction.
So long, see you next year!
