The ongoing drought in California has led to increased groundwater contamination across the state, Reuters reported.
The contamination has particularly affected rural communities where wells supply water to residents. With less water available, groundwater contaminants become more concentrated.
Last year, 183 communities were identified as dependent on contaminated groundwater. The state has assisted 22 of those communities, and is preparing to help the rest. Ten communities have been named for immediate relief.
President Barack Obama recently announced that the federal government will contribute nearly $200 million in aid for California, some of which will help food banks feed jobless agricultural professionals.
