Drinking Water Quality


99.89%

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 Listing
Treatment Description
Alkalinity Adjustment Chemical processes used to control the pH and the alkalinity of raw water to enhance the removal of contaminants or to neutralize treated water where treatment processes have made the water chemically unstable (corrosive). Lime is the most commonly used substance in this process because it is readily available and inexpensive.
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.
pH Adjustment Chemical processes used to control the pH and the alkalinity of raw water to enhance the removal of contaminants or to neutralize treated water where treatment processes have made the water chemically unstable (corrosive).
Sedimentation A process that slows the flow of water through a drinking-water system to allow suspended material to settle due to gravity.
