Chesapeake Bay clean up: For more than 20 years, Pennsylvania along with the states of Maryland and Virginia and the District of Columbia have been spending millions of dollars and implemented dozens of environmental changes, all designed to clean up the Chesapeake Bay. According to its annual report, the Chesapeake Bay Foundation says the nation's largest estuary is still in danger and gave the bay a "D" grade. The report says the bay continues to be harmed by high levels of nitrogen and phosphorus that come from sewage plant discharges, lawn and farm fertilizers and animal waste. After 20 years, is there hope?
