Habitat Loss and Degradation

Increasing development pressure and human activities have negatively impacted the natural habitats and the diversity of life in the Peconic Estuary.

Climate Change

Climate change is profoundly impacting the Peconic Estuary through increasing water temperatures, changes in precipitation patterns, sea level rise, and ocean acidification.

Nitrogen Pollution

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

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.

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.

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.
