Cleaning Up a National TreasureThe Chesapeake Bay is the nation's largest watershed. At seven thousand square miles it supports more than 36 hundred species of plants, fish and animals, with 15 million people living near its basin.
While it's one of the world's most important watersheds, it's also one of the dirtiest. Recent surveys have revealed more than 80 percent of the water does not contain enough oxygen in the summer, killing fish, crabs, oysters and plant life. The Chesapeake Bay Initiative, a multi-state agreement, was developed to change that.
As part of the agreement, Maryland, Virginia, Pennsylvania and the District of Columbia have agreed to reduce nitrogen and phosphorous discharge into the bay area by 2010. Over 70 wastewater facilities will have to enhance their nutrient removal process by using more natural methods, like bacteria, instead of harmful chemicals. These efforts are part of a larger commitment to restore the bay to its original condition.
