                         Yes, the tap water in the City of St. Catharines is safe to drink because it meets
                         strict Ministry of Environment requirements. The City is required to take hun-
                         dreds of samples each month and test for a variety of parameters including
                         chlorine, E. coli and other bacteria. The City has also implemented a community
                         wide lead testing program. All technicians and laboratories involved in analyzing
                         drinking water must meet stringent certification and accreditation requirements.

                                       Did You Know?
  Every year over 3000 drinking water samples are taken and tested for a variety of parameters,
  including: E. coli, total Coliforms, free chlorine residual, lead, turbidity, hardness, sodium,
  trihalomethanes (disinfection by-products), iron, copper, magnesium... just to name a few. Samples
  are taken daily throughout the distribution system from over 100 different sampling sites, including
  schools, businesses, community and senior centres, hospitals and private homes.
