A wind turbine generates energy above agricultural crops in Madison County, New York. Wind energy is just one of the many ways federal, state and local partners are working to reduce air pollution across the Chesapeake Bay region.

Polluted air doesn’t just cloud the air we breathe—it can also have quite an impact on water quality. Experts estimate that one-third of the nitrogen in the Bay comes from the air through a process known as atmospheric deposition. Wind and weather can carry the pollution emitted by power plants, airplanes, cars and other sources over long distances until it falls onto land or directly into the water.

While the area of land that drains into the Bay spans six states and 64,000 square miles, the Bay’s “airshed”—the area of land over which airborne pollutants travel to enter the estuary—is nine times that size. This makes far-reaching efforts like the Clean Air Act essential in reducing the amount of pollution that reaches the Bay. Alternative sources of energy like hydropower dams, manure and poultry litter, wind turbines and solar panels can also help lessen the amount of energy-related pollution emitted into the air.
