California's record-setting drought might be making coastal waters less prone to bacteria. In 2015, for example, 762 beach closures were issued for San Diego County's 46 beaches. The majority were closed because of rainfall pushing runoff into the ocean, but about one-fifth of closures were because of bacteria. That trend is on the downswing, according to an EPA database called BEACON 2.0.
