Cleanup crews for East Bay Municipal Utility District were busy Wednesday extracting four vehicles from near the San Leandro Reservoir, a key water source for Bay Area residents. The extraction comes just a day after the agency cleaned up 10 tons of material from a similar location on Tuesday and a month after extracting eight other abandoned cars in July. There’s been an epidemic of abandoned cars in the Bay Area for years, especially in the East Bay, but EBMUD spokesperson Andrea Pook says the problem was exacerbated by the pandemic.
