One-third of the drinking fountains in Montgomery County's public schools contain water with excessive amounts of lead, and there are 10 schools where lead levels are more than four times the federal safety standard, according to recent tests.
A study initiated by Silver Chips,indicates that the lead content in Blair's drinking water averages 25 parts per billion (ppb), a level which exceeds and Environmental Protection Agency (EPA) guidelines that will be put into effect in June, 1989.
We found 1730 results.
