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 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.

As a lifelong resident of Highland Park, and currently a student at Rutgers I have greatly enjoyed hiking throughout the university’s Ecological Preserve, a relatively pristine area located on the Livingston Campus. The Rutgers Preserve was established in 1976 as an ecological resource. Its purpose is to serve as an aesthetic, educational, and recreational area for the Rutgers community as well as for the residents of New Jersey. This 360-acre Eco-Preserve is the habitat of numerous creatures including migrant songbirds (warblers and towhees). It is also the home of the white-tailed deer. The Preserve is the site of native plants such as Spring Ephemerals and Jack-in-the-Pulpit, as well as Ash, Beech, Hickory, and Red Oak trees.
Anyone concerned with environmental matters in the Lower Raritan Watershed should be aware of the proposed Rutgers “Innovation Park” (IP) plan – an infrastructure project to be constructed adjacent to the Rutgers Eco-Preserve site. Rutgers has requested that the New Jersey Commission of Budgeting and Planning allocate $4.75 billion for infrastructure projects on its campuses as part of a Master Plan. Included in this proposal is funding for IP, a major project to be built on the edge of the Preserve. According to the Rutgers publication Business Plan and Implementation Strategy (2016), its purpose is to “promote research collaborations, technology transfer and commercialization, job creation, and public-private partnerships.” IP, an inter-disciplinary learning site with a goal of furthering environmentalism is well-intentioned.
However, a project whose mission is environmental may nevertheless be harmful to the Preserve’s ecosystem. A major building project occurring just outside the Eco Preserve’s borders may well threaten fauna and flora within the Preserve itself. The project will result in pollutants from trucks and construction machinery as well as in greater noise levels. Fossil fuel emissions, the primary cause of climate change, have already caused the destruction of species of animals and plants worldwide. Excessive construction noise is harmful to the well-being of animals and plants as fossil fuel emissions and increased decibel levels will not stop at the Preserve’s periphery. The essential question is to what degree, the site will be impacted.
If it has not yet done so, Rutgers must conduct a thorough environmental review of the effects of this infrastructure project. Although in the Rutgers publication there is an environmental assessment of the IP site itself, there is no reference to its impact on the adjacent Eco-Preserve. There should be a comprehensive environmental assessment regarding how the IP project will impact this area. Residents of Central New Jersey and beyond, including members of the Rutgers community who care about protecting this vital habitat, must be given the opportunity to interact with those involved with this project.
