Drinking Water Quality
100%
April 1, 2011 - March 31, 2012
The number shown in this box represents a percentage of all the drinking water quality test results done during the time period indicated that met the Ontario Drinking Water Quality Standards. Includes test results of health-related standard parameters only; operational testing data (ie, chlorine and turbidity) are not included in final water quality results.
Inspection
100%
April 1, 2011 - March 31, 2012
The Ministry of the Environment has a comprehensive inspection program to ensure that municipal residential drinking water systems operate in compliance with regulatory requirements.
Every municipal residential drinking water system is inspected at least once a year, with one in three inspections unannounced.
The ministry's annual inspection ratings are designed to encourage drinking water systems to strive for continuous improvement and ultimately to meet the ministry's long-term goal of 100 per cent compliance by all systems.
Treatments
Treatment processes reduce or eliminate the potential for the presence of pathogens (organisms that can cause illness) in drinking water and are used to ensure your drinking water meets provincial standards. Different water sources necessitate different levels and methods of treatment to ensure safe, clean water is provided.
| Treatment | Description |
|---|---|
| Chlorination | The addition of chlorine to raw or filtered water for disinfection purposes or for the purpose of maintaining a consistent level of chlorine in a drinking-water distribution system. |
| Coagulation | A chemical process that causes smaller particles to bind together and form larger particles. The process is used to improve the removal of particles through sedimentation and filtration in the drinking-water treatment process. |
| Filtration | The separation of suspended solid particles from a fluid stream by passing it through a granular or membrane filter that retains all or most of the solids on or within itself. |
| Flocculation | The gathering together of fine particles in water by gentle mixing after the addition of coagulant chemicals to form larger particles that can then be removed by sedimentation and filtration. |
| Fluoridation | The addition of fluoride to drinking water for the purpose of reducing tooth decay. There is generally little or no naturally occurring fluoride in water taken from surface water sources. |
| Taste and Odour Control | A series of treatment procedures used to control the taste and odour of water, including chemically assisted filtration, aeration, chlorination, superchlorination, ozonation and activated carbon treatment. Algae, algae by-products, other complex organic compounds, hydrogen sulphide or iron can all affect water taste and odour. |
| Zebra Mussel Control | Methods used to reduce or prevent the impact of zebra mussels on drinking-water systems. A zebra mussel infestation can block or reduce an intake pipeline's capacity to draw water. |
