PG&E has been ordered to provide clean water sources to the town of Hinkley whose groundwater was contaminated, inspiring the film Erin Brockovich.
More than 200 homes will be provided a water filtration system or new wells that tap a deeper, unpolluted aquifer.
Officials say residents in Hinkley have been living off bottled water since January 2011 but water in kitchen sinks and showers is still contaminated with chromium. In a groundbreaking case, Brockovich proved the utility used hexavalent chromium to fight corrosion in its equipment, later polluting groundwater.
