HONOLULU (AP) - Hawaii is the only U.S. state that didn't exceed federal testing limits for lead in drinking water during the last three years, and the Hawaii Department of Health says it's because the state's lucky to have lots of volcanic soil and few lead pipes.
Hawaii health and water officials say there are multiple factors that help keep the islands' tap water clean. Those include abundant groundwater sources, few industrial pollutants and water systems built without lead.
An analysis of U.S. Environmental Protection Agency Data by The Associated Press found nearly 1,400 water systems serving 3.6 million Americans have exceeded the federal lead standard at least once between Jan. 1, 2013, and Sept. 30, 2015. Of those, over 275 exclusively serve schools and daycares, some of which reported levels among the highest in the nation.
