According to recently released data from California’s Water Resource Board, approximately 700,000 California residents are being exposed to contaminated tap water. The data shows that 292 water systems in California have levels of arsenic, uranium, nitrates, and lead contamination that violate safe drinking standards. These numbers fail to capture the full extent of the problem, however, as the data does not represent people that rely on private wells and doesn’t measure Chromium-6 contamination. Among the systems affected are ones serving schools, such as La Mirada Elementary School in San Diego, where tests revealed elevated levels of lead, copper, and bacteria. The discovery of lead at La Mirada prompted water testing in at least 12 different San Diego schools, three of which also found elevated lead levels.
California residents are no strangers to water contamination. A 2016 study found nearly 3,000 ZIP codes across the country in which children had higher lead levels than children in Flint, Michigan, with eight of those ZIP codes located in California. Much of California’s water contamination is in the rural communities of the Central Valley. West Fresno, where life expectancy is 20 years less than Northeast Fresno, has been described as one of the riskiest places to live in California due to combination of “diesel exhaust, tainted water, pesticides and poverty.” California’s water problems have been attributed to inadequate funding and management. While the state offers grants to build treatment centers and other infrastructure, smaller communities don’t always have the resources for operations and maintenance.
