Water Testing Services for Private Wells Provided by Renfrew County and District Health Unit


Renfrew County and District Health Unit provides water testing services for residents who have private drinking water systems.

If you get your drinking water from a well, you should have it tested for bacteria at least three times per year. Testing times should be spread out over the year, for example during or just after a spring melt, in mid-summer and in the fall. In addition to regular testing, well water should be tested:

  • after any work to pumps or plumbing
  • if the well has not been used for several weeks
  • if there has been flooding in the area, or
  • if there has been a change in water colour or odour

Water testing is free. Sample bottles can be picked up at Health Unit offices. Sample bottles can also be picked up at all municipal offices in Renfrew County and District.

Instructions for taking the sample come with the water sample bottles. Follow the instructions carefully and write all of the information requested on the sample form.

Take the sample as close as possible to the time you will be dropping it off for testing. If you are not dropping off your sample right away, keep it in the fridge or a cooler.


There are five locations throughout the County where you can drop off your water sample.  The closest one for Laurentian Valley residents is:

Interpreting your water test results

Public Health Inspectors are there to help you understand what your water results mean and how to fix any problems with your drinking water. Call the Health Unit at 613-735-8654 or 1-800-267-1097 extension 555.

Do not rely on the test results of only one water sample. The Health Unit recommends you take three samples taken one to three weeks apart to make sure your drinking water is safe to drink.

If you want to check for chemicals in your well water, you need to contact a lab or a water treatment company. Call the Health Unit for more information.
