Why test
Well water can look, smell and taste perfect while carrying bacteria. It can also change: after a wet spring, a flood, nearby construction or work on the well itself. Testing is the only way to know.
What to test for
- Bacteria, specifically total coliforms and E. coli. This is the routine safety test.
- Nitrates, especially near farmland or septic systems.
- Hardness, iron and manganese, which affect taste, staining and equipment.
- Other chemistry such as sodium, sulphide or fluoride, when there is reason to suspect a problem.
How to get it done
Across Ontario, bacteria testing for private wells has been offered free through public health labs, with sample bottles available from local public health offices. Halton Region’s public health service is the place to check for current pick-up and drop-off locations and timing. Chemical testing usually goes through a private accredited lab, for a fee.
- Collect the bottle and instructions.
- Fill it at a cold tap with the aerator off and no treatment in line, after running the water.
- Keep it cold and deliver it within the time allowed.
- Read the results and keep them on file.
Schedule: public health guidance has generally suggested testing for bacteria several times a year, plus after any flood or well work.
If a test comes back bad
Stop drinking the water and use bottled or boiled water as advised by public health. Shock chlorination of the well, followed by retesting, is a common first step. Repeat problems point to the well itself, the cap, surface water getting in, or a nearby source, and may justify an ultraviolet system or well repairs.
Where we come in
Our crews look after well pumps, pressure tanks and treatment gear, and we can install UV, iron and softening equipment sized to your test results. We do not interpret lab health results; public health does that. Owners in areas such as Timberlea are on town water and do not need this routine.
Questions we get asked
Do Ontario well owners pay for bacteria tests?
The bacteria test has been provided at no charge through public health labs. Check current arrangements with Halton public health.
How often should I test?
Several times a year for bacteria is common guidance, plus after floods or well work.
Does a UV system replace testing?
No. Keep testing to confirm the system is doing its job.
