Providing a pump out service (VHF Channel 9) in both Black Rock Harbor, Johnson’s Creek and the Bridgeport Harbor area goes a long way toward our goal of establishing and maintaining an eco-friend- ly environment that all of us on our waters can be proud of.

  • 2017 Bacteria Data
    2017 Bacteria Data - Western Coastal waters: Enterococci and fecal coliform Two groups of bacteria are are commonly monitored to indicate the presense of human sewage and associated pathogens, or disease causing organisms - fecal coliforms and enterococci. The Rhode Island Department of Health (RIHealth) uses a single- value enterococci standard for licensed swimming beaches. The Rhode Island Department of Environmental Management (RIDEM) and Connecticut Department of Energy and Environmental Protection (CT DEEP) use a geometric mean approach for contact recreation standards on all other waters (fresh and salt). In addition, as required by the National Shellfish Sanitation Program for shellfish waters and their tributaries and as an indicator of overall water quality, fecal coliform levels are also assessed. While URIWW's Analytical Laboratories are certified by the State of Rhode Island, Watershed Watch data is intended for screening purposes only. Our data are very valuable for targeting areas of concerns and for tracking potential sources of bacterial contamination. Samples may have been collected over a period of days for each collection period, so may reflect dry versus wet weather or rain event values. Please contact Watershed Watch for specific sample dates. Any result above the state standard is considered unsafe, and swimmers should refrain from swimming until results return to acceptable levels, or at least for several days after heavy rain.

  • Contract 17-04 Anguilla Brook Bacteria Trackdown and Watershed-Based Plan Eastern Connecticut Conservation District January 2
    EASTERN CONNECTICUT CONSERVATION DISTRICT, INC. www.ConserveCT.org/eastern Contract 17-04 Anguilla Brook Bacteria Trackdown and Watershed-Based Plan Eastern Connecticut Conservation District January 28, 2020 Task 1d – Conduct Water Quality Sampling This project is funded in part by CT DEEP through a US EPA Clean Water Act §319 Nonpoint Source Program grant. Introduction The Eastern Connecticut Conservation District (ECCD) has received funding from the Connecticut Department of Energy and Environmental Protection (CT DEEP) through the Clean Water Act Section 319 Nonpoint Source program to conduct water quality sampling of perennial steams in North Stonington and Stonington, Connecticut that discharge to Wequetequock Cove and develop a watershed-based plan for the Anguilla Brook watershed (Fig. 1). Wequetequock Cove is an embayment of Little Narragansett Bay, located at the outfall of the Pawcatuck River at the boundary between the States of Connecticut and Rhode Island. The Inner Wequetequock Cove estuary (CT_E1_003), located in Stonington, is listed in the State of Figure 1. The Anguilla Brook watershed, located in North Stonington and Stonington, CT. Connecticut’s biennial Integrated Water Subwatersheds are outlined in gray. Quality Report to Congress as not meeting its designated uses for habitat for marine fish, other aquatic life and wildlife, recreation, and direct consumption of shellfish due to estuarine bioassessments, excess algal growth, and high levels of enterococcus and fecal coliform bacteria, respectively (CT DEEP, 2017). Potential pollutant sources include stormwater, agricultural activities, and other unidentified upstream sources. ECCD conducted bacteria sampling from June to August of 2019. Sampled streams include Anguilla Brook (CT2101-00_01), Wheeler Brook (CT2101-01_01), an unnamed tributary to Wheeler Brook (CT32101-02_01), and Donahue Brook (CT2101-03_01).
