The brown in the Bay Waters is largely a plume of sediment, the raw material necessary to rebuild wetlands and maintain their health. That sediment, though, is mixed up with pollutants — toxic mercury from old mines, Lester McKee, a scientist with the San Francisco Estuary Institute tells News Group.

Why is the Chesapeake Bay not clear?

Boaters have glimpsed the bottom of a vast estuary that for years has been murky, thanks to constant agricultural runoff pouring in from rivers and streams, producing dense algae growth.

Is the Chesapeake Bay contaminated?

More than three-quarters of the Chesapeake Bay's tidal waters are considered impaired by chemical contaminants. From the insecticides that are put on farm fields to the cleaners we use to disinfect our homes, contaminants can enter the Bay and its tributaries and harm the health of both humans and wildlife.

What is the largest source of pollution in the Chesapeake Bay watershed?

Can dead zones be fixed?

Wetlands can help remove nutrient pollution causing low-oxygen “dead zones.” But how much benefit we reap depends a lot on placement, a new study finds.
