LEAD CONCERNS

Parents Demand New Tests of School Water

A group of Washington area parents and environmentalists has formally demanded that the U.S. Environmental Protection Agency order new tests of water in D.C. public schools, saying they don't trust local officials' assurances that some unusually high lead levels detected in school water in recent months were "isolated" findings.

The parents contend that they've been misled before about the severity of lead problems in the city's water supply. In a letter last week to the EPA, they argued that the D.C. school system's method for broader systemwide testing in February was skewed to register artificially lower lead levels. They said local and federal officials have given unclear and conflicting answers when questioned about the testing method's accuracy.

"We are very alarmed about the safety of our children, and nobody is giving us any straight answers," said Yanna Lambrinidou of Parents for Non-Toxic Alternatives, which joined in urging the EPA to intervene. "I have a basic question as a parent: Is the water safe for my child to drink at the fountain?"

The letter was sent on behalf of 50 parents, joined by organizations such as Clean Water Action, the D.C. chapter of Friends of the Earth and the Center for Health Environment and Justice.

The parents expressed concern that high lead readings in drinking water at five schools could signal a citywide problem. High lead levels are often a sign of dangerously corrosive water and posed a major health hazard in the city from late 2001 to 2004, after which the water utility changed the chemicals it used to treat the water.

Federal and local water utility officials say they have no fear of a citywide water problem and note that required sampling indicates the supply's lead levels fall below the federal threshold for concern.

EPA officials based in the Philadelphia regional office, who are responsible for monitoring the quality of the District's water, said they are reviewing the parents' allegations and had no immediate response to the demand for more testing.

Tests conducted from June to January found that 30 to 80 percent of the water fountains and taps in the five schools had elevated, unsafe lead levels; all told, 16 schools were tested. One fountain in a kindergarten class had a lead reading of 1,200 parts per billion. The EPA recommends that lead levels in school drinking water not exceed 20 parts per billion and urges that schools seek to reduce the amount to as close to zero as possible.

The school system did not inform parents or school board members about the results, which became public only after a D.C Council hearing. At the urging of Mayor Adrian M. Fenty (D), the school system began fast-tracked testing at all schools and reported this month that it generally found safe lead levels.

The group of parents and environmentalists makes two central allegations. The first is that the school system has tried to give them false assurances, issuing news releases with the "good news" that 87 percent of the recent school tests met federal standards. But on further questioning, parents learned that at least one water fountain, cooler or sink in about three-quarters of 129 city schools for which data were available had elevated, unsafe levels of lead.

The second is the contention that the school system's testing method artificially lowered the systemwide lead test results. At the urging of the D.C. Water and Sewer Authority and with the EPA's knowledge, the school system flushed the water in each of the tested schools for 45 to 50 minutes before taking samples. WASA distributes the city's drinking water.

Paul L. Taylor Jr., a facilities maintenance official of the school system, said the city used a certified laboratory for the tests and developed the procedures in consultation with WASA and the EPA.
