The County Health Department conducted recent tests which showed high bacteria levels in the water exceeding the State Water Quality Standards.
Beaches along Toms River, Beachwood Beach West in Beachwood, Summit Beach in Island Heights, and West Beach in Pine Beach, were closed Tuesday. The Washington Avenue beach was closed out of precaution due to the closures of surrounding Ventnor beaches, the DEP's New Jersey Cooperative Coastal Monitoring Program said. Avoid water contact in the advisory area.
Officials at the New Jersey Department of Environmental Protection believe heavy rainfall is to blame, which caused pollution to runoff into streams that feed into those beaches.
Seven Jersey Shore beaches closed heading into weekend
Brissette Beach was initially closed on July 13 after tests revealed E. coli levels four times higher than normal.
Health officials say they will also continue to monitor the bacterial levels. A beach closes if two consecutive samples at a bathing beach are higher than the state standard.
