Lower Raritan Pathogens Results for 10.22.2020
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.
Below are our pathogens results for October 22, 2020.
Field notes for October 22, 2020
Fog blanketed much of the East Coast through the morning, and hung heavy over the Raritan until burning off around noon. Called “advection fog,” the mist forms when warm, moist air passes over a cool surface. Advection describes the movement of fluid, in this case the fluid is wind. When the moist, warm air made contact with the cooler surface air, water vapor condensed to create fog.
Ever wonder how all the rain that falls onto a highway is “disappears” for a safe driving experience? It is transferred via stormwater infrastructure — that is, pipes or channels — to and “outfall” at which the stormwater enters receiving waters (rivers, streams, or creeks). This outfall at New Brunswick’s Boyd Park conveys rainwater from Route 18 (above the arches) into the Raritan River at the Rutgers Class of 1918 Boathouse.
It is so unfortunate that South Amboy Waterfront Park has too many pathogens to count! This was so close to my hometown of Sayreville and the waterfront is a popular site to visit. Thanks for sharing this information!
