Pathogen Management

Contamination of Peconic Estuary waters by bacteria and other pathogenic organisms may result in the closure of bathing beaches and the closure of shellfish beds for human consumption; thus impacting economic and recreational activities on the East End. The Peconic Estuary Program is working with its partners to reduce pathogen pollution from stormwater runoff and wastewater.

Current Actions

Subwatershed Management Plans

To decrease the amount of pollutants entering the water via stormwater we need to do our part to change what we do on land. PEP has worked to establish subwatershed management plans to address the pathogen loads to waterbodies troubled with pathogen pollution, and to date has created 12 subwatershed management plans.

These plans focuses on identifying cost‐effective structural and non‐structural practices to reduce overall pollutant loadings (i.e. bacteria, sediment, nutrients) and runoff volume to the subwatershed. Successful implementation of these plans is expected to help reduce stormwater runoff pollution and improve overall water quality conditions. This should in turn improve shellfish harvesting capacity, eelgrass habitat, and degraded marsh areas.

Intermunicipal Agreement

PEP established a collaboration of East End municipalities to share resources and work together on projects to reduce stormwater runoff, reduce pollution from septic system discharges, agricultural and residential fertilization, groundwater flows, illegal dumping, floatable debris and boat waste.
