"Lead Tests on NY City Schools’ Water May Have Masked Scope of Risk"
"When the results of tests for lead in the water at more than 1,500 New York City school buildings were announced in July, officials said that fewer than 1 percent of all the samples taken showed lead concentrations that exceeded Environmental Protection Agency guidelines. Given other safety measures in place, officials assured parents, the water was safe to drink. But a review of how the testing was conducted suggests that the amount of lead in the water that students consume could be greater than the results indicate."
