Federal authorities are closing a southern Arizona road for a day to clean up illegal dumping of sulfuric acid.
U.S. Bureau of Land Management officials say the dumping was recently discovered near the Battle Axe Road trailhead parking area in Superior.
They say the spill created a public health hazard near the junction of Battle Axe Road and State Route 177.
Cleanup is expected to be completed by June 15. The road will be closed the day before while crew clean up.
BLM officials say an environmental emergency response contractor will excavate, containerize, remove and dispose of sulfuric acid contaminated soils at a licensed landfill.
