PPG Industries, in conjunction with the Centers for Disease Control and Prevention (CDC), will participate in a free webinar for environmental health professionals on preventing recreational water illnesses (RWIs). The webinar, presented by NSF International, takes place on Tuesday (May 4) at 10 a.m. PST.

This webinar is specifically geared toward health inspectors and environmental health professionals, but the information shared is also vital to anyone who operates a recreational water facility, according to a news release.

Presenters include Michele Hlavsa, RN/MPH, epidemiologist from the CDC; Dr. Stanley Pickens, PPG senior research associate for the Accu-Tab®system commercial pool water treatment group; and Richard Martin, business manager, NSF International.

  • Hlavsa, who works with the CDC’s waterborne disease prevention branch, will discuss prevention and remediation of RWIs. Specifically, she will focus on prevention of Cryptosporidiosis outbreaks and will provide helpful steps to limit the severity of outbreaks. Cryptosporidium, also known as crypto, is a type of protozoan parasite that accounts for approximately two-thirds of gastrointestinal illness outbreaks at treated recreational water venues.
  • Dr. Pickens’ portion of the presentation will address the impact cyanuric acid (CYA) has on disinfection rates and on hyperchlorination to kill Cryptosporidium. CYA is a common chemical that stabilizes chlorine levels.
  • Martin will discuss how the use of pool equipment tested and certified to NSF/ANSI Standard 50 will help assure recreational water facility operators of safe, reliable equipment performance.
