"Californians relying on small water utilities to bring drinking water into their homes, or who work or go to school in places providing their own water, are far more likely to be exposed to lead, according to a new analysis of Environmental Protection Agency data by The Desert Sun and USA TODAY.
Small public water systems across the state made up the vast majority of systems found to have high levels of lead in their drinking water or testing violations since 2010, the analysis found. These systems typically exist in rural areas and serve less than a few thousand people. Some serve only a few hundred or even a few dozen people, sometimes at a single school or business.
The results are evidence that while most water utilities across the state have clean records when it comes to lead, smaller agencies with limited resources struggle more often to comply with safety protocols. Neither the state nor the small water systems have the capacity to monitor for safety of drinking water as often as larger water systems do. Regulators are encouraging consolidation and a new law requires any new small system coming on line to first consider joining an existing system."
