Santa Barbara County health officials are strongly recommending that residents and visitors avoid ocean and creek waters for at least 72 hours following rainfall. This advisory comes amid heightened concerns over stormwater runoff, which can carry various pollutants into coastal waterways, particularly as El Niño conditions increase the potential for heavy rain and stronger storms.
The primary reason for this caution is the risk of exposure to contaminants. Stormwater runoff collects bacteria, chemicals, trash, and other pollutants from streets, yards, and agricultural areas. These contaminants are then transported into local creeks and the ocean, posing health risks to anyone coming into contact with the water. Kimberly Ray, who works in marine conservation, explained that "All the chemicals are coming from land," noting that substances from lawns, agriculture, and general trash on land ultimately enter these waterways.
Even when ocean or creek water appears visually clean, it may contain harmful bacteria and other unseen contaminants. Exposure to such contaminated water, whether through swallowing, inhaling water droplets, or direct skin contact, can lead to illness. Common health issues include gastrointestinal infections and, in some instances, respiratory problems. Jason Johnston, environmental health services director for Santa Barbara County, reiterated the official stance that it is "our recommendation" to avoid ocean and creek waters for 72 hours after rain.
For some beachgoers, the appeal of warm water after a storm can be strong, but county officials and local residents caution that these conditions can be misleading. Kitt Doucette, a Carpinteria resident, observed the unusual warmth of the water, but added it did not have the "chemical smells that I’ve seen before." Doucette also advised that certain coastal areas require increased vigilance, describing them as "dicey."
To help residents make informed decisions, the county provides an online water quality map. This resource allows beachgoers to review current conditions at various beaches throughout Santa Barbara County before deciding to enter the water. Given the potential for increased runoff into local waterways due to upcoming rain, officials continue to advise checking these advisories and adhering to the 72-hour waiting period before engaging in activities like swimming or surfing in the ocean or creeks. This recommendation is a preventative measure designed to reduce the risk of illness from waterborne contaminants following rain events.
