The Environmental Protection Agency, also known as EPA, is proposing a higher standard of testing lead in drinking water in schools as well as in day cares, wanting to tighten the rules even more.

Critics are saying that it would take decades to replace systems in schools that could possibly have higher traces of lead.

Andrew Wheeler, who is the EPA Administrator, made the announcement of these proposed changes to better control lead contamination in the drinking water.

EPA is calling this their biggest overhaul on these rules since the 90's with lead water pipes.

This proposal would require water suppliers to test the water at schools as well as day cares for lead.
