In an increasingly shrill battle overGOP efforts to roll back environmental regulations, EPA head Carol Browner warned local officials late Wednesday that one in 10 Americans drinks from a water system that violates public health standards. "We cannot take the safety of our drinking water for granted," Browner told a group of local officials. "More remains to be done." GOP House members want to do less. Hours earlier, a subcommittee voted to gut the long-sacred Clean Water Act, which protects lakes, rivers and streams from pollution.TIME Washington correspondent Dick Thompsonnotes that Browner, whom Republicans are now attacking for running a "partisan" EPA, is losing the fight. The water overhaul should pass the House in May, Thompson says, and theEndangered Species Act"likely won't survive in any form we recognize."
