(KYMA, KECY/ CNN) - The California Department of Justice is now investigating last week's massive oil spill off the coast of Huntington Beach.
A pipeline ruptured and spewed thousands of gallons of crude into the Pacific Ocean.
During a news briefing Monday, the State Attorney General called the spill an environmental disaster with far-reaching consequences for fish and wildlife, the community and economy.
Huntington Beach reopened its shoreline Monday after testing results found no detectable amounts of oil-associated toxins in the ocean water.
Beach-goers were warned to report noxious smells-- and avoid areas with oily materials and tar balls.
The state DOJ said in a statement it's working to assess whether the emergency could have been prevented or minimized.
