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.
A blanket of fog hovered over our monitoring sites, including Riverside Park in Piscataway
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.

Our fisher friends in Edison didn’t seem to mind the fog. They told us they had just caught and released a 26-inch striper the night before.

Below are our pathogens results for October 1, 2020. These are about the worst results of the season so far. Two of our sites had colony forming units (cfus) that were TNTC or “too numerous to count”.
Please note: results are preliminary and pending quality control.
Field Notes for 10.1.2020
Our sites may be “dirty” but they are also beautiful, and places where many go for fishing, recreation, and to learn more about the natural and constructed world.
Gorgeous views at our Riverside Park (Piscataway) site belie what are typically our worst pathogens counts for all monitored sitesOur friends at the Edison Boat launch site told us the water was too dirty to catch anything but eels. LOTS of trash floating in the water at this site this week.This is the fifth week of red tide conditions at our monitoring site in South Amboy

Here are our pathogens results for September 10, 2020. Please note that we received over an inch of rain in our Lower Raritan monitoring areas the evening after monitoring. As such we expect pathogens levels to be much higher than what was sampled in the morning.
Please note: results are preliminary and pending quality control.
Pathogens Results for Raritan River Public Access Non-Swimming Beach Sites
Field Notes for 9.10.2020
Lots of rain while monitoring our first three sites on September 10, 2020 made for a soggy day. The water at all sites was dark brown and thick with sediment from upstream. Our rain gauge showed 1.52 inches when we checked it the morning after monitoring. Most of that rainfall occurred on September 10 between 7-10 pm. Please take extra care when in any waterway after rainfall, especially heavy rains that send so much sediment and waste into our local streams and River.
In addition to capturing water quality samples we collect data on salinity, temperature, dissolved oxygen, pH and other parametersSample bottles for genetic source trackdown, analysis conducted by Rutgers Fahrenfeld Lab
Genetic analysis will help us pinpoint the source of fecal loads in our waterways

Summer 2020 Raritan Monitoring Sites
The New Jersey state Department of Environmental Protection and Middlesex County Health Departments typically monitor at sanctioned public swimming beach sites. They do not monitor the water quality for pathogens at public access non-swimming beach sites along the Raritan, despite regular use of these areas for primary contact (fishing and swimming) by members of our urban communities.
The LRWP works with in partnership with the Interstate Environmental Commission for lab analysis of our samples. We have a Quality Assurance Protocol Plan (QAPP) approved by the federal Environmental Protection Agency. We work to report our results as soon as lab analysis is completed.
You can find more information on our monitoring sites here, and an overview of our pathogens monitoring program here.

Field Notes
Yesterday was an exquisite day for sampling the Raritan!
Clear and gorgeous waters, and the re-purposing of a broom handle into our snazzy new sampling stick.Thanks to Maya and NJ Watershed Ambassador Heather Miara for lending a hand in the field.Thanks also to IEC’s wonderful Jessica Bonamusa for meeting us in the Elizabeth IKEA parking lot for the sample handoff.This week we kick off our genetic source trackdown analysis – the larger sample bottle in the mix of pathogens sample bottles will go to a Rutgers lab for filtering and analysis. We’re looking forward to more definitively pinning our pathogens problems on human, beast or fowl.
