After Rain, Avoid Swimming at Beaches: County – NBC 7 San Diego

processing...

San Diego County is in the middle of its first fall storm of the season. With that rainfall, the County is warning residents to stay away from swimming at San Diego beaches because of a rise in bacteria levels from urban runoff.

No local beaches were closed as of Wednesday morning, according to the County’s Beach and Bay Water Quality Program site

The worst urban runoff is typically near storm drains, creeks, rivers and lagoon outlets which contain bacteria from animal waste, soil or decomposing vegetation, according the San Diego County Department of Environmental Health.

Matt O’Malley with San Diego Coastkeepers said it’s not just bacteria lurking in urban runoff that people should be worried about, but also pesticides and toxic metals from aging infrastructure.

The County’s Beach and Bay Water Quality Program’s interactive map showed a General Rain Advisory for dozens of local beaches in San Diego County from Oceanside to Imperial Beach. As of Wednesday morning, the Tijuana River’s status was at a low risk. The Tijuana River can impact California beaches when it rains, sending sewage and other contaminants into local beaches, according to the County.

The San Diego County Department of Environmental Health said that rain advisories are issued when the rainfall is equal to or greater than .20 inches. The County advisory is in effect for 72 hours after the last rain.

Some kiteboarders were seen riding the waves, despite the current advisory.

“Any chance to get out when it’s windy and get out kiteboarding, we’re going to take,” kiteboarder Alan Mondus said.
