Report: State’s Drought is Reducing Coastal Bacteria

New data from the Environmental Protection Agency suggests that the lingering drought in California is actually making coastal waters less prone to potentially harmful bacteria.

There were 762 beach advisories in San Diego County in 2015 for example. At their peak two years earlier, there were almost twice as much. As the state’s drought worsened, bacteria in the water declined, resulting in fewer closures and advisories overall.

The explanation is rather simple.

“Storm drain runoff is the greatest source of pollution to local beaches, flowing untreated to the coast and often contaminated with motor oil, animal waste, pesticides, yard waste and trash," says Heal Bay. So less precipitation has meant less contamination.
