  • Ecological Condition of US Mid-Atlantic Estuaries, 1997–1998
    Marine Pollution Bulletin 46 (2003) 1224–1244 www.elsevier.com/locate/marpolbul Review Ecological condition of US Mid-Atlantic estuaries, 1997–1998 John A.Kiddon a,*, John F.Paul b, Harry W.Buffum c, Charles S.Strobel a, Stephen S.Hale a, Donald Cobb a, Barbara S.Brown a a US Environmental Protection Agency, Office of Research and Development, National Health and Environmental Effects Research Laboratory, Atlantic Ecology Division, 27 Tarzwell Drive, Narragansett, RI 02882, USA b US Environmental Protection Agency, ORD, NHEERL, Research Triangle Park, NC 27709, USA c Computer Sciences Corporation, 27 Tarzwell Drive, Narragansett, RI 02882, USA Abstract The Mid-Atlantic Integrated Assessment (MAIA-Estuaries) evaluated ecological conditions in US Mid-Atlantic estuaries during the summers of 1997 and 1998.Over 800 probability-based stations were monitored in four main estuarine systems––Chesapeake Bay, the Delaware Estuary, Maryland and Virginian coastal bays, and the Albemarle–Pamlico Estuarine System.Twelve smaller estuaries within the four main systems were also assessed to establish variance at the local scale.A subset of the MAIA-Estuaries data is used here to estimate the extent of eutrophication, sediment contamination, and benthic degradation in mid-Atlantic estuaries.An Envi- ronmental Report Card and Index of Environmental Integrity summarize conditions in individual estuaries, the four estuarine systems, and the entire MAIA region.Roughly 20–50% of the region showed signs of eutrophication (high nutrients, excessive production of organic matter, poor water clarity, or depleted dissolved oxygen), 30% had contaminated sediments, and 37% had degraded benthic communities.Compared with the Environmental Monitoring and Assessment Program (EMAP)-Virginian Province study in 1990– 1993, larger fractions of Chesapeake Bay (17%) and Delaware River (32%) had increased metals or organics in sediments.

McPherson (410) 238-4255 (410) 238-4210 Below Normal Rainfall and Warm Temperatures Lead to Record Low Water Levels in December Three months of above normal temperatures and four months of below normal rainfall have led to record low monthly streamflow and ground-water levels, according to hydrologists at the U.S. Geological Survey (USGS) in Baltimore, Maryland. Streamflow was below normal at 94 percent of the real-time USGS gaging stations and 83 percent of the USGS observation wells across Maryland and Delaware in December. Record low streamflow levels for December were set at Winters Run and Pocomoke River. Streamflow levels at Deer Creek and Winters Run in Harford County have frequently set new record daily lows for the last four months (see real-time graphs at http://md.water.usgs.gov/realtime/). Streamflow was also significantly below normal at Antietam Creek, Choptank River, Conococheague Creek, Nassawango Creek, Patapsco River, Gunpowder River, Patuxent River, Piscataway Creek, Monocacy River, and Potomac River in Maryland, and Christina River, St. Jones River, and White Clay Creek in Delaware. The monthly streamflow in the Potomac River near Washington, D.C. was 82 percent below normal in December and 54 percent below normal for 2001. Streamflow entering the Chesapeake Bay averaged 23.7 bgd (billion gallons per day), which is 54 percent below the long-term average for December.

FAQs – Polluted Runoff and Fees POLLUTED RUNOFF IN BALTIMORE COUNTY Baltimore County contains the headwaters for many of the streams and tributaries feeding into the Patapsco River, one of the major rivers of the Chesapeake Bay. These tributaries include Bodkin Creek, Jones Falls, Gwynns Falls, Patapsco River Lower North Branch, Liberty Reservoir and South Branch Patapsco. Baltimore County is also home to the Gunpowder River, Middle River, and the Back River. Unfortunately, all of these streams and rivers are polluted by nitrogen, phosphorus and sediment and are considered “impaired” by the Maryland Department of the Environment, meaning the water quality is too low to support the water’s intended use. One major contributor to that pollution and impairment is polluted runoff. Polluted runoff contaminates our local rivers and streams and threatens local drinking water. Water running off of roofs, driveways, lawns and parking lots picks up trash, motor oil, grease, excess lawn fertilizers, pesticides, dog waste and other pollutants and washes them into the streams and rivers flowing through our communities. This pollution causes a multitude of problems, including toxic algae blooms, harmful bacteria, extensive dead zones, reduced dissolved oxygen, and unsightly trash clusters.
