Gregory Pierce, adjunct professor of urban planning and associate director of research at the Luskin Center for Innovation, spoke to Arizona PBS about the presence of lead in California’s drinking water. California is testing pipes and upgrading plumbing at public schools across the state, the article noted. Nearby homes typically share the same water systems, but “there’s no required testing for these privately owned places, which may result in many people not knowing that the water they are using for showers, cooking and drinking purposes may have lead contamination,” Pierce said. The article cited a UCLA report card on water quality in Los Angeles County, where some residents perceive that their tap water is unsafe. “With the lack of trust in their water, these lower-income residents and areas are now having to rely on water stores, or having to buy drinks such as juice or soda because they believe there are issues with their water.”
