Well Water

How Well is Your Well?

Ground water is usually clean and safe for consumption. Because the overlying soil acts as a filter, groundwater is usually free of disease-causing organisms. However, contamination can occur as a result of improper installation of well casings or caps, after a break in the casing or as a result of contaminated surface run-off water entering the well.

Contamination can also occur in wells which are drilled in fractured bedrock without an adequate layer of protective soil or do not have the recommended minimum casing length. Proper location, construction and maintenance of your well is important.

To learn more about drinking water safety, contact the Health Unit toll-free at 1-866-888-4577, ext. 5006 and speak with the Public Health Inspector.

Testing Your Well Water

If you get your water supply from a private well, you need to test the water to be sure it is safe.

Drinking water that has harmful bacteria in it can make you sick. These bacteria can cause you to have stomach cramps, nausea and/or diarrhea, as well as other medical problems. The only way to make sure that your water supply is safe to drink is by regular testing.

Testing for bacteria is done free of charge. Sample bottles can be obtained at any Health Unit office or designated location (link to locations). Follow the sampling procedure and then return the bottles to the Health Unit. Samples will be sent the provincial lab for testing and the results sent back to you through the mail.
