HAGERSTOWN, Md. (AP) — The federal government asked a judge Thursday to dismiss a developer’s lawsuit alleging that groundwater pollution from Fort Detrick in Frederick reduced the value of private land next door.

The Justice Department said concerns about potential pollution from an old chemical dump site on the Army installation had prompted state environmental regulators to prohibit any use of groundwater beneath the parcel long before Waverley View Investors LLC acquired it through bankruptcy in 2012.
