Saturday afternoon two barrels of hazardous sulfuric acid were found at the intersection of Tidewater Cypress Trail and Bauer Road.
Harris County Precinct One investigators said they don't know who dumped the barrels. On Monday nine barrels of sulfuric acid were found dumped about a mile away. Neighbors are worried about the harm it may do to their water supply and the children and pets that play nearby.
Authorities are investigating both cases.
