Guam’s public pool rules establish how pools are permitted, built, staffed, and operated. They cover everything from water quality and chemical storage to when a lifeguard or attendant must be present. This guide packages the essentials from the regulation into checklists and action steps. Where training or credentials are mentioned, we reference American Aquatics and Safety Training (AAST) for Lifeguarding plus CPR/AED/First Aid (per your branding preference).
By understanding these laws, pool operators and managers can avoid costly violations and ensure a safe swimming environment. Families, homeowners, and swim instructors will also find these rules useful for promoting safety and confidence in and around the water.

Guam’s code defines an aquatic facility (the place) and aquatic venues such as swimming pools, spas/hot tubs, spray pads, wave pools, lazy rivers, therapy pools, and wading pools. If the general public can use the water, even through splash or aerosol exposure, it’s likely regulated. The rules also define higher-risk venues (e.g., spray pads and wading pools used by young children) that require enhanced disinfection.
No. Hotels, motels, and private campgrounds are not required to post a lifeguard, but must have an attendant who can be readily summoned to assist. Many other public facilities choose to staff lifeguards for safety, liability, and insurance reasons. When lifeguards are used, they must be fully focused on patron safety (no distracting duties).
Keep pH between 7.2–7.8. Maintain disinfectant residuals (e.g., free chlorine typically ≥1.0 ppm without cyanuric acid; ≥2.0 ppm with cyanuric acid; spas ≥3.0 ppm). Verify clarity so main drains or a six-inch black disk at the deepest point are clearly visible from the deck. Test before opening and every 1–2 hours while open, and log results.
Increased-risk venues, including wading pools, spray pads (recirculating), and therapy pools, must use an ANSI/NSF 50-listed secondary system designed for a 3-log (99.9%) Crypto inactivation per pass. The secondary unit is placed post-filtration and sized to the venue’s volume and downtime.
Hotels need an attendant who can be easily located when the pool is open; ensure clear rules signage (e.g., “No Diving” markers where applicable), chemical and equipment rooms secured, and bathhouses/diaper stations compliant. Consider voluntary lifeguard coverage during peak hours for added risk reduction.

Updated for 2026. This article was reviewed in 2026 and the guidance below reflects how the course is run now.
Renewal is worth planning for rather than reacting to. There is no abbreviated recertification: a renewing guard sits the same instruction, the same written examination at 80 percent, and the same skills evaluation as a first-time candidate.
What does not vary with the code is the certification an inspector looks for. Guards on duty are expected to hold CPR/AED for Professional Rescuers covering adults, children and infants, valid for two years.
