lead in water

The South Jersey school said that the age of the buildings involved will be a factor in coming up with a permanent solution, because lead was a commonly-used material used in plumbing until it was banned in 1986.

Most school districts are not required to test water for lead. But many are testing anyway — with disturbing results.

It's hard to find out how many schools have discovered high levels of lead in their drinking water.

Dr. Steven Marcus, executive director of the New Jersey Poison Information & Education System, said even the smallest amount of lead in children can shave off IQ points.

Gov. Chris Christie will meet the media for the second time in two days at the StateHouse on Tuesday to talk about lead remediation and containment efforts. Watch the press conference here live starting at 2 p.m.
