GARYVILLE, La.—A massive fire at a Louisiana oil refinery that sent a tower of black smoke billowing into the air above the Mississippi River is mostly contained, but residents still worried about health effects from the fumes and smoke.
Tests have so far found “non-detectable air quality impacts” from Friday’s massive fire, Marathon Patroleum said in a emailed statement Saturday. The state Department of Environmental Quality and a third-party contractor were conducing the tests.
