NEWPORT BEACH, CA - February 11th, 2026 - Orange County residents and visitors are being urged to exercise caution near coastal waters following a widespread bacteria warning issued by the Orange County Health Care Agency (OCHCA). The current advisory, initially focused on Newport Beach, now extends to several other key coastal areas due to persistent rainfall over the past week. While the initial warning stemmed from elevated bacteria levels near Newport Beach, monitoring has revealed similar increases across Huntington Beach, Laguna Beach, and Dana Point.

Issued on Tuesday, February 10th, the warning advises the public to avoid swimming, surfing, or engaging in water activities in affected areas. Contact with the ocean water should be minimized until further notice. This isn't simply a localized issue; it's a recurring pattern highlighting the vulnerability of Southern California's coastline to stormwater runoff and its impact on public health.

The primary culprit behind the elevated bacteria levels is runoff from recent and ongoing rainfall. Stormwater carries a cocktail of contaminants into the ocean, including animal waste, fertilizers, oil, and other debris. These pollutants create a breeding ground for various bacteria, most notably fecal coliforms and Enterococcus, which can cause gastrointestinal illnesses, skin infections, and respiratory problems. The increased concentration of these microorganisms presents a health risk to anyone coming into contact with the water.

"We've seen a significant increase in rainfall over the last seven days, exceeding the average for this time of year," explains Dr. Emily Carter, a microbiologist with the OCHCA. "This saturation of the land means more runoff, and unfortunately, our urban and agricultural landscapes contribute a substantial amount of bacteria to that runoff. It's not a reflection of a breakdown in our wastewater treatment facilities, but rather the sheer volume of water overwhelming the natural filtering capacity of the coastal environment."

The OCHCA is conducting daily water quality testing at multiple locations along the Orange County coastline. Samples are analyzed for indicator bacteria - specifically, Enterococcus - which serve as a proxy for the presence of other harmful pathogens. The advisory will remain in effect until bacteria levels consistently fall within acceptable standards, typically requiring three consecutive days of clear testing results.

This situation underscores a growing concern about the impact of climate change on coastal water quality. More frequent and intense rainfall events, predicted by climate models, will likely exacerbate the issue of stormwater runoff and increase the frequency and duration of these bacterial warnings. Local municipalities are beginning to explore and implement green infrastructure solutions, such as permeable pavements, rain gardens, and restored wetlands, to help mitigate runoff and filter pollutants before they reach the ocean. However, these long-term solutions require significant investment and time to implement effectively.

For residents and tourists, the OCHCA recommends the following precautions: Avoid swimming or surfing in ocean water for at least 72 hours after rainfall stops. If contact with ocean water occurs, shower thoroughly with soap and water. Be mindful of any open wounds or cuts, and seek medical attention if symptoms of illness develop, such as fever, nausea, vomiting, diarrhea, or skin rash. Stay informed about water quality conditions by checking the OCHCA website ([ https://www.ochealthinfo.com/ ]) and local news sources for updates.

The city of Newport Beach is also increasing signage along its beaches warning of the potential health risks. Lifeguards are actively patrolling the area and advising beachgoers to heed the warning. The impact on local businesses, particularly those reliant on tourism and water sports, is being closely monitored. While the advisory is necessary to protect public health, it inevitably leads to cancellations and lost revenue.

The OCHCA is working with local water districts and environmental agencies to address the root causes of the problem and implement long-term solutions to improve coastal water quality for years to come. This recent event serves as a stark reminder of the interconnectedness between land-based activities and the health of our marine environment.
