PEP Accomplishments

PEP is making significant change. See here for accomplishments and current PEP projects.

Ongoing Monitoring Programs

PEP works with a number of partners to monitor the condition of water quality and essential habitats in the Peconic Estuary.

Clean Waters

PEP is taking action to reduce nitrogen pollution, harmful algal blooms, pathogens, toxic contaminants, and plastics in the Estuary to support the well-being of people and wildlife.

Nitrogen Pollution

Nitrogen pollution has been identified as one of the greatest threats to the Peconic Estuary due to its far reaching impacts, including harmful algal blooms, hypoxia, fish kills, and high treatment cost for drinking water.

Toxic Contaminants

Toxic chemicals can concentrate in the aquatic environment and directly affect the ability of fish, shellfish, wildlife, and plants to survive and reproduce.

Pathogen Pollution

Viruses, bacteria, fungi, and protozoans that cause diseases in humans, animals or plants. High levels of these pathogens may make shellfish unsafe to eat and water unsafe for swimming.

Improve Your Septic System

Increased wastewater treatment from residential septic systems and cesspools is needed to protect our groundwater and surface waters from the negative impacts of nitrogen pollution.

Plastic Pollution

Plastic pollution in the aquatic environment is harming wildlife and human health.
