County Executive Leopold Calls for Additional Monitoring of Aquifers for Fly Ash Contamination

Study raises serious public health concerns

Annapolis, MD (December 30, 2010) - County Executive John R. Leopold has asked the Maryland Department of the Environment to increase water quality monitoring around the Gambrills fly ash disposal site after new findings by a Johns Hopkins study about potential groundwater contamination.

"I continue to have great concern for the migration of fly ash in ground water, since Anne Arundel County residents rely on a series of public wells as their drinking water source," County Executive Leopold wrote in a letter yesterday to Robert Summers, Acting Secretary of the Department. "The public wells draw ground water from the Lower Patapsco aquifer and are located down gradient from the site."

"There is no evidence that the public water supply has been affected by the ground water contamination at the fly ash site," Leopold continued. "However, the request for additional monitoring wells is a measure being taken to protect public health and to assure the public that municipal water supply wells will remain unaffected by contamination."

Working with the County Council, County Executive Leopold has executed three successive bans on fly ash disposal in the County with another one-year ban pending. Leopold has also vocally opposed a pending permit allowing Constellation Energy to dispose of fly ash in Baltimore just over the Anne Arundel County line.
