Matheny Tract residents first received notice in 2006 that their drinking water, provided to them by Pratt Mutual Water Company, was contaminated with an excessive amount of arsenic. Pratt Mutual’s distribution system was deteriorating, and residents were clearly paying the price. Matheny Tract is a small, unincorporated community made up of 1,200 residents. The majority of the population is Latino, and almost a third of the residents live below the federal poverty line. Since the community is unincorporated, residents can’t vote in city elections and don’t have access to municipal services.
