Water Testing and Well Records

Water Testing: Submit a Well Water Sample

At the Public Health Ontario Laboratories, water testing is FREE. They test for the indicators of bacterial contamination: coliforms and E. coli.

  • Coliforms. These bacteria are often found in animal waste and sewage, and soil and vegetation. If they are in your drinking water, it means surface water may be entering your well.
  • E. coli (Escherichia coli ). These bacteria are normally found only in the digestive systems of people and animals. If they are in your drinking water, it usually means that animal or human waste is entering your well from a nearby source.

How to take a Water Sample

It’s important to collect your sample properly. The accuracy of your test results depends on it.
