KNOW THE GUIDELINES BEFORE YOU INVEST IN A SWIMMING POOL:
The World Health Organization has published international guidelines for the safety of swimming pools and similar recreational-water environments, including standards for minimizing microbial and chemical hazards.[1] The United States Centers for Disease Control and Prevention also provides information on pool sanitation and water related illnesses for health professionals and the public.[2] The main organizations providing certifications for pool and spa operators and technicians are the National Swimming Pool Foundation and Association of Pool & Spa Professionals. The certifications are accepted by many state and local health departments.[3]
Make sure to check with your state and local governments to insure you are following the correct guidelines for installing and maintaining your swimming pool. Also your pool professionals should be knowledgeable about these guidelines, so they follow them when building, installing and maintaining your swimming pool. Make sure to ask!
