Top 10 Foggers and Disinfectants for Public Swimming Pools and Swimming Spots: Lessons from Elevated E. coli at California's Sycamore Pool, 2026
Sycamore Pool in Chico tested above the E. coli threshold, a year after four children fell ill with O157 and their families sued the city. What should Thai public pools and swimming spots prepare?
The Real Story from the News: No-Swim Signs Posted
North State Public Radio reported on 7 August 2026 that a water sample from Sycamore Pool in Bidwell Park, Chico on 3 August showed E. coli above the city's swimming safety threshold, about a year after four children were sickened and as four families sue the city.
The city posted no-swim signs and asked people to stay out of the water until conditions improve; routine tests measure general E. coli rather than the O157 strain, which needs separate testing.
Why Choosing the Right Equipment Matters
Water quality depends mainly on testing and treatment, and foggers do not disinfect water. But public pools also have changing rooms, showers, toilets and decks that stay wet and busy all day, so routine washing and disinfecting of these areas plus clear warnings when readings are off are standards operators should keep.

Prefer Not to Do It Yourself? Use a Professional Service
If buying equipment is not practical or the area is too large, use the World Health Disinfection disinfection service or ozone treatment service. The team wears full protective equipment, chooses products to suit the germ and surface, and reports after the job.
Frequently Asked Questions
Q: Can foggers disinfect pool water? A: No. Pool water needs treatment systems; foggers and disinfectants are for showers and surrounding areas.
Q: How long before the area can be used? A: After ULV fogging, areas are typically usable about 30 minutes later. For ozone treatment, no people or pets may be inside and the room must be ventilated before use.
Q: Can I get a tax invoice? A: Yes. Tax invoices are issued and 3% withholding tax is supported. Call 065-556-6294 or LINE @whd268.
Health References
Follow disease updates from Thailand's Department of Disease Control (hotline 1422) and the World Health Organization. Disinfection reduces germs in the environment and is not medical treatment; anyone with symptoms should see a doctor.
