      Why test pool water?

• Essential part of both
  Public Health and the
  general maintenance
  and life of the Pool.
• To assure both, the
  pool operator must do
  a number of simple
  water tests.


                P bar Y Safety Consultants Alberta Canada
  Maintenance = Good Health


Poor maintenance of the pool may lead to
  low levels of disinfectant (chlorine) and
  clogged filters that may place swimmers at
  risk for diarrheal diseases and skin, ear, and
  upper respiratory infections.

FECAL ACCIDENTS

                           • Fecal accidents can
                             release large amounts
                             of contaminated
                             material into a pool or
                             spa at one time.
                           • Every pool needs an
                             established
                             procedure.


    P bar Y Safety Consultants Alberta Canada
         FECAL ACCIDENTS
• MOST DIARRHEAL OUTBREAKS IN POOLS
  APPEAR TO BE RELATED TO ACCIDENTAL
  FECAL CONTAMINATION OF THE WATER
  BY SOMEONE WHO IS ILL WITH
  DIARRHEA.




            P bar Y Safety Consultants Alberta Canada
         Cryptosporidium

• Major germ that
  causes outbreaks.
• Extreme chlorine
  resistance.
• Small size.
• Will challenge even
  the best equipped and
  maintained pool.
                                        Crypto in human intestine


               P bar Y Safety Consultants Alberta Canada
E. coli 0157:H7

                          • Rare occurrence in
                            chlorinated pools.
                          • Only two reported to
                            Centers For Disease
                            Control.
                          • High profile cases
                            because of deaths
                            associated with
                            incidents.

            Three Main Tests
• Residual disinfectant and disinfectant by-

• Water Balance (pH, Total Alkalinity, Calcium
  Hardness, Temperature)
• Undesirable residual chemicals (Sulphates,
  Chlorides, Cyanurates)



                P bar Y Safety Consultants Alberta Canada
            The Big Two
