Raritan River Pathogens Results for 9.10.2020

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.

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 parameters

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.

Pathogens Monitoring Results for 8.20.2020

The LRWP and EARTH Center of Middlesex County monitors 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.

Briefly, our Sayreville, South Amboy and Perth Amboy sites are looking good this week! Please note that these results for August 20, 2020 are preliminary and awaiting Quality Control.

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.
