Purisoft offers free professional water testing in our service area. Outside this region, contact your local municipality or a certified water testing laboratory.
Unlike municipal water, which is treated and tested before it reaches your tap, well water comes directly from the groundwater beneath your property. That means your water quality depends on your local geology, the depth of your well, how it was constructed, and what's happening on the land around you.
Two neighbours on the same road can have completely different water. One can have crystal-clear, soft water. The next door over can have iron staining, sulphur smell, and hardness off the chart — all from wells drilled 100 feet apart. This is why a lab test is essential before you invest in treatment equipment.
Groundwater in most of Ontario, the Prairies, Quebec's St. Lawrence valley, and PEI passes through limestone and dolomite bedrock — which dissolves calcium and magnesium into your water. Well water hardness is often higher than nearby city water.
Very common in Canadian wells. Iron above 0.3 mg/L causes orange/brown staining on fixtures, toilets, laundry, and dishes. Manganese above 0.05 mg/L causes dark grey or black staining. Both cause metallic taste and can damage appliances.
Hydrogen sulphide gas occurs naturally in groundwater, especially in deeper wells. Even at very low concentrations it creates a strong rotten-egg smell. Treatment is chemical-free with an air injection iron/sulphur filter.
Health Canada guideline: zero detectable coliform bacteria in drinking water. Well water can become contaminated through surface water intrusion, cracked well caps, or nearby septic systems. Any detection means UV sterilization is critical.
A serious concern in agricultural areas. The Health Canada limit is 45 mg/L as NO3 (or 10 mg/L as NO3-N). High nitrates are especially dangerous for infants. Only reverse osmosis or specialized filtration removes nitrates.
Common in areas with granite or sandstone bedrock. Acidic water (pH below 6.5) corrodes copper pipes, causing blue-green staining and eventually pinhole leaks. A neutralizing filter raises pH to protect your plumbing.
Yellow or brown tinted water, typically in wells near wetlands, peat bogs, or forested areas. Tannins come from decaying organic matter. A specialty tannin filter removes them.
Health Canada recommends testing well water for bacteria at least twice a year — spring and fall — and for chemistry (hardness, iron, pH, nitrates, minerals) at least once a year. Test any time you notice a change in taste, smell, or appearance, after well work or plumbing changes, and before buying a home with a well.
Your lab report will list each parameter with a measured value and typically a flag for anything outside acceptable ranges. Upload your report to our tool and we'll do the analysis for you — explaining in plain English what each number means for your home, whether treatment is needed, and what equipment is sized correctly for your household.
Your uploaded water test report is analyzed instantly and never stored on our servers. We don't require a signup to use the tool. If you choose to email yourself a detailed report, your email is used only to send that report — never shared or sold.
