Residents are being advised to avoid the shoreline and wooded area near the intersection of Arundel on the Bay Road and Bay Highlands Drive in Highland Beach because of a sewer main break Tuesday.

The break was reported at 9:20 a.m., and the 12-inch main was repaired by 4:30 p.m., said Pam Jordan, spokeswoman for the Anne Arundel County Department of Public Works.

The break caused the release of about 90,000 gallons of wastewater, some of which entered Oyster Creek.

Officials with the state Department of the Environment and the county Health Department met at the site Tuesday and are advising all residents who come into contact with spillage to wash their hands and clothing immediately. Officials were expected to meet again yesterday to determine what further cleanup is necessary.
