Four water fountains in Lake Forest schools have tested above the national standard for lead.
The U.S. Environmental Protection Agency allows no more than 15 parts per billion of lead in drinking water. Three water fountains in the hallways of Lake Forest High School had levels of 19 parts per billion, 17.3 parts per billion and 18.9 parts per billion, according to results posted on the District 115 website.
A fountain in the west cafeteria at Deer Path Middle School had a lead level of 22 parts per billion, according to the results.
The affected fountains at both schools were closed down, according the district. Though not required, the district has also shut down 10 fountains and two sinks in the schools that tested between two and 15 parts per billion.

“Why do anything other than err on the side of caution?” said Superintendent Michael Simeck. “We want to ensure that all our water sources are below the reportable limit.”
Simeck said the testing was done voluntarily by both districts.
According to the EPA website, lead and copper primarily enter drinking water through plumbing materials such as pipes, fittings and fixtures.
“Exposure to lead and copper may cause health problems ranging from stomach distress to brain damage” according to the EPA.
Districts 67 and 115 have not yet determined whether the fountains are repairable or if they should be closed permanently.
Simeck said from now on, the districts will test all water sources annually.
