State lawmakers are considering a bill that would lower the maximum amount of lead allowed in schools across Long Island.

A recent study by the New York League of Conservation Voters found that schools on Long Island had more lead in their water than other schools across the state, but the levels are considered safe.

Federal guidelines allow a maximum of 15 parts per billion. The bill that's before lawmakers would lower the maximum amount to 5 parts per billion.

Julie Tighe, president of New York League of Conservation Voters, says children are especially vulnerable to the effects of lead.

"The American Academy of Pediatrics will tell you that there are really no safe levels of lead in drinking water -- or anything," says Tighe. "So we really want to take action and Long Island in particular stood out as having the most number of outlets that are exceeding 5 parts per billion."

Assemblyman Fred Thiele, who is a co-sponsor of the bill, says it's important to protect the children and have clean drinking water.

"It's one of those no-brainer bills where we're going to do more to protect drinking water and protect our children and protect public health and there's no unfunded mandate for our local school districts," says Thiele.

The proposal is pending before the state Assembly and Senate. Both chambers are expected to pass the measure.
