Well Water Testing & Compliance
Private wells serve millions of rural Canadians with water no one regulates but the owner. Provinces provide free or subsidized bacteriological testing precisely because contamination is common and silent — and well compliance extends beyond the water itself: well records, proper caps and grading, setbacks from septic systems, and the legal duty in most provinces to properly decommission abandoned wells, which act as direct contamination conduits to the aquifer.
Testing done properly
Bacteriological testing (total coliform, E. coli) should run at least three times yearly per provincial guidance — after spring melt especially — via public health labs where provinces offer it free. Chemical panels (nitrates near agriculture, arsenic and uranium in known geology, sodium for treated-road areas, lead from plumbing) run less often but matter more where they matter. For transactions, lenders and insurers commonly require recent potability results — we arrange the full protocol with proper sterile technique, which is where DIY samples fail.
The well itself
Compliance items owners inherit: a sanitary well cap, casing height and sealed annulus, surface grading away from the wellhead, setbacks from septic and fuel storage, and the provincial well record documenting construction. Missing records complicate sales and grant applications; we retrieve them from provincial registries or arrange assessments that reconstruct what exists.
Treatment and abandoned wells
Where results demand treatment — UV for bacteria, RO for arsenic/uranium, softening — certified equipment with maintenance verification is the standard insurers and buyers accept. Abandoned wells on the property must be decommissioned by licensed well technicians under provincial rules; an old dug well under a shed is both a legal liability and a child-safety one.
How the process works
- Tell us the property, well type if known, and the purpose — routine, transaction, or concern.
- Sampling runs with proper protocol to accredited/public-health labs.
- Results are interpreted against Canadian drinking water guidelines.
- Treatment or well repairs are arranged where indicated.
- Well records, decommissioning and transaction documentation complete the file.

Frequently asked questions
Is well testing free?
Bacteriological testing through public health is free or nominal in most provinces (Ontario, the Maritimes notably). Chemical panels are paid lab work — worth it on purchase and every few years thereafter.
My water tastes fine — why test?
E. coli, arsenic, nitrates and uranium are tasteless. Taste tells you about minerals and aesthetics, not safety — the entire reason testing programs exist.
What if coliform comes back positive?
Resample to confirm, inspect the wellhead for entry points, disinfect (shock chlorination), retest — and if positives persist, continuous treatment (UV) plus finding the cause. E. coli positives mean stop drinking it now, treat, and investigate.
The property has an old unused well — can we just leave it?
Provincial rules generally require proper abandonment by licensed technicians (sealed with approved materials, documented). It is commonly flagged in rural transactions now, and grants sometimes offset the cost.
