"Climate change is making our restoration efforts more challenging. More severe storms are bringing more pollution into the bay," McGee said.
What’s happening here has become a case study on just how hard it is to clean up and restore vital watersheds and estuaries, as well as reverse the impacts of pollution and global warming even as costly plans are being put in place nationwide to push back against climate change.
Environmentalists first started realizing how polluted the Chesapeake was back in the 1970s. By 2010, government agencies, nonprofits and environmentalists started taking action to clean it up.
"People across the country were saying, 'We need to watch this,' because they are setting themselves up for success. They have plans. They have accountability that no other watershed has had," McGee added.
Thirteen years later, though, progress has been slow.
Across the lower 48 states, there are 78 major watersheds, essentially basins catching water from rivers as they hit the sea. But of the more than 700,000 miles of waterways in the U.S., nearly 51% are impaired by pollution.
"One hundred years ago, people didn’t give rivers and streams much thought," explained Matt Ehrhart with the Stroud Water Research Center. "Clean, fresh water is one of the most vital resources we have."
Ehrhart says that these days, most pollutants in our nation's watersheds come from agriculture. Fertilizers and pesticides used on crops often run off into nearby rivers and streams. There are other causes, like runoff from the road salt we use in the winter.
"It’s critical the way we live on the landscape doesn’t unduly impact those resources," he added.
