California Gov. Gavin Newsom revealed new details of his plans to charge water customers in the state a new tax to fund safe drinking water for disadvantaged communities. He announced Wednesday his plans to charge water customers an extra amount ranging from 95 cents to $10 a month — money that, combined with fees on animal farmers, dairies and fertilizer sellers, he projects would raise $140 million a year that could be put toward testing wells, aiding public water systems and treating contaminated water. The amount paid would depend on the size of one’s water meter.
