State lawmakers could vote this week on a plan requiring public water systems to alert residents within two days after high levels of lead are detected. It's part of an overhaul of rules governing how the state and its cities deal with lead in drinking water. Current federal rules give water plants 60 days. The Ohio Water Utility Council, a trade group, says the 2-day deadline could distract water operators at a time when they should be focused on the lead problem, and a 5-day deadline would be better.
