COLUMBIA, S.C. (AP) -- South Carolina environmental regulators have ordered more testing to avoid possible contamination by a toxic industrial chemical.
The State newspaper reported that the board at the Department of Health and Environmental Control on Thursday ordered more testing at wastewater treatment plants to look for PCBs.
Officials worry the chemicals could show up in sewage sludge that farmers use to fertilize their fields.
State lawmakers would have to approve the proposed rules dealing with sludge. There were complaints by utilities, farmers and sludge haulers at an earlier public hearing that the new rules were too restrictive.
DHEC says the rules should give the agency a better evaluation of the scope of PCBs in sludge across South Carolina.
PCBs are considered a probable cancer-causing material for humans.
