Emergency OASIS Act

This bill requires community water systems to flush their pipes if contaminants exceed safety limits for over six months or if water has been stagnant for six months. It mandates the EPA Administrator to order flushing, test for specific contaminants (like arsenic) at 10-25% of service connections, and provide alternative water supplies within seven days if systems fail to do so. Water systems cannot raise customer fees to cover these costs, and the EPA may charge owners double the cost of alternative water if they don’t comply.
