The Bay Journal is reporting that a lower-cost way to control nitrogen that goes into Chesapeake Bay is being used along a river that has its headwaters in Delaware.
Drew Koslow, who has been active in environmental matters for decades in the area, has installed a half-dozen bioreactors on farms in Maryland along the 70-mile-long river that flows from the Delaware border in Kent County into Maryland and the Chesapeake Bay.
The reactors take water from farms to a pit filled with buried wood chips that can cut nitrogen content from manure or fertilizer by 50 percent or less.
Nitrogen is a problem in both Delaware and Maryland, with the First State dealing with issues on its inland bays near the Atlantic Ocean.
Delaware also has the Nanticoke River which flows from Kent County into Chesapeake Bay. Seaford is the largest Delaware community along its banks.
