Drinking water systems would have to notify their customers if their water fails to meet EPA standards, under legislation approved by the Idaho House on Monday.

Rep. Marvin Vandenberg, D-Coeur d’Alene, proposed the bill for the second year in a row. Last year, it passed the House, but the Senate questioned whether it duplicated existing law, he said.

Research since then showed it didn’t. Vandenberg did make a minor wording change in the law.

It passed the House unanimously, and now heads to the Senate.
