School districts should test drinking water supplies for lead during summer vacation, the Water Quality Association said. Water studies and media reports over the past school year show lead exposures is an ongoing concern nationwide, stemming primarily from aging infrastructure, especially in rural parts of California. “Many more states are requiring schools to test their drinking water,” said Pauli Undesser, WQA executive director. “We believe schools can take advantage of the summer month to conduct a thorough test in accordance with their state’s laws or guidelines and determine if specific water treatment is required. It should be a top priority.”
