Happy Memorial Day Weekend!
For those of you making plans to be on the water, see below for enterococci results for our monitoring sites, reported in Colony Forming Units or CFUs. Please note that while we follow quality control measures, the real-time nature of data delivery means that EPA has not reviewed, and these are not technically quality controlled.
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.
Suitable levels for enterococci in marine (salt) waters are 104 – 501 cfu/100mL for a single sample, and for freshwater 61 – 151 cfu/100 mL as a single sample reading.
Briefly put, the numbers look good for our New Brunswick, Sayreville and South Amboy sites. Numbers are bad for our Piscatway and Edison sites, and downright horrible for our Perth Amboy site.
Riverside Park (Piscatway, 40.54067, -74.51219): 6300 CFU
Rutgers Boat House (New Brunswick, 40.48826, -74.43384): 51 CFU
Edison Boat Basin (Edison, 40.48769, -74.38409): 640 CFU
Ken Buchanan Waterfront Park (Sayreville, 40.47483, -74.35586): <10 CFU
South Amboy Waterfront Park (South Amboy 40.48334, -74.2698): <10 CFU
2nd Street Park (Perth Amboy 49.50007, -74.27719): TNTC or Too Numerous to Count. (This number is >60,000.)
Huge thanks to our partners EARTH Center of Middlesex County and the New England Interstate Water Pollution Control Commission. We are working to develop a platform for data reporting and sharing, but for now see our program overview for more information on the sites and our monitoring efforts.
