Mapping Pollution Hot Spots in the Chesapeake Bay

…from NPR

“Biologist Kristin Politano taps a canister of sediment to get oxygen bubbles to rise. She learned about nutrient pollution in Florida, but in some ways it’s the same in the Chesapeake. Scientists can map the pollution hot spots, but someone has to follow them back to source to fix the problem.

“”It all boils down to what we’re actually putting into the watershed,” says Politano. “People get upset about what’s going on in the bay. What they have to realize is that a lot of the problems are coming from the upper watershed themselves. You have to look at restoring headwaters and streams, and rivers and things like that before you are going to see an improvement in the water quality that’s coming into the bay.””
