Water Testing in North Bay
Water testing in North Bay is a diagnostic service from Poly-B Plumbing for homes and cottages on private wells, lake intakes and municipal water in North Bay, Callander, Sturgeon Falls, Powassan and the surrounding communities. A water test is a set of measurements, hardness, iron, sulfur, pH and dissolved solids done on site in minutes, plus bacteria and full chemistry sent to an accredited lab, that tells you what is in the water before anyone sells you a system to treat it. Poly-B explains the results in plain language and recommends treatment, or nothing, based on the numbers. Call 705-345-6616.

What Poly-B tests for, and what each result means
| Test | Where it is done | What a bad result looks like at home | Health or nuisance |
|---|---|---|---|
| Total hardness (grains per gallon) | On site, minutes | Scale in the kettle, spots on glasses, stiff laundry | Nuisance; hard on water heaters and fixtures |
| Iron and manganese | On site | Orange or black staining, metallic taste | Nuisance at typical levels |
| Hydrogen sulfide | On site | Rotten-egg smell, worse from the hot tap | Nuisance; corrodes fittings |
| pH | On site | Blue-green stains, pinholes in copper | Nuisance that becomes a repipe |
| Total dissolved solids | On site | Taste, cloudiness, film | Sizing input for treatment |
| Coliform and E. coli | Accredited lab, sterile sample | Nothing you can see or taste | Health; treat before drinking |
| Nitrates and nitrites | Lab | Nothing visible; shallow wells near fields or septic | Health, especially for infants |
| Sodium, chloride, and other chemistry | Lab | Salty taste near roads; relevant on sodium-restricted diets | Health for some households |
Who should test their water, and how often
- Every private well, once a year for bacteria, and after any flooding, well work or a change in taste, smell or colour. Spring, after the melt, is the sensible time around North Bay.
- Anyone buying a rural property. A water test is routinely required for financing on a well, and the results are negotiating information.
- Cottages on Lake Nipissing or Trout Lake drawing from a lake intake or a shallow well, every season.
- Any home with staining, smell, scale or pinhole leaks, because the fix is different for each cause and the test is what tells them apart.
- Before buying any treatment equipment. A softener bought for an iron problem treats nothing.
The free bacteria test, and what Poly-B adds to it
Ontario tests private well water for coliform and E. coli at no charge through Public Health Ontario’s laboratory; sample bottles and drop-off are handled through the North Bay Parry Sound District Health Unit. Poly-B Plumbing recommends every well owner use it, every year. What the free test does not do is measure hardness, iron, sulfur, pH, dissolved solids, nitrates or the chemistry that decides what treatment a house needs, and it does not sit at your kitchen table and explain what the numbers mean. Poly-B does the on-site mineral testing, collects the sterile sample properly when a full lab panel is wanted, and interprets everything together, because a licensed plumber who also installs the treatment is the person who can tell you when you need none.
What water testing costs in North Bay
Poly-B Plumbing quotes water testing flat-rate, in writing. The price depends on:
- On-site only or with lab. On-site mineral results are same-day; lab bacteria and chemistry take about five to seven business days and carry the lab’s fee.
- How many points. A raw-water sample at the well and a treated sample at the tap tell you whether an existing system is working.
- Combined visits. A test done during an annual inspection, a well pump service or a pre-purchase inspection is priced with it.
Members of the $49-per-month plan get annual water test reminders and 10 percent off any treatment system the results call for.
What the water is like around North Bay
Inside the city, the Trout Lake supply is membrane-filtered, disinfected with UV and chlorine, and dosed with caustic for pH adjustment and corrosion control before it reaches the mains; the City publishes annual water quality reports. Outside the city there is no plant. Wells around Corbeil, Astorville, Bonfield, Nipissing and Redbridge are drilled into Canadian Shield bedrock and typically produce soft, slightly acidic water that carries iron, sometimes sulfur and manganese, and that dissolves copper plumbing from the inside over the decades. Shallow and dug wells, and lake intakes, can carry tannins and bacteria after a wet spring. That range is why the test comes before the equipment.

Where Poly-B tests water
Water testing questions from homeowners around North Bay
Is this different from the health unit’s water test?
Yes. The health unit route is a free lab test for coliform and E. coli, which Poly-B Plumbing recommends every well owner use annually. Poly-B adds on-site testing for hardness, iron, sulfur, pH and dissolved solids, full chemistry at the lab where wanted, and a plain-language explanation of what to do.
Can Poly-B help if the results are bad?
Yes. Poly-B Plumbing installs softeners, iron and sulfur filters, sediment filters, neutralizers and UV systems, sized to the results, and says so when the results call for nothing.
How fast are the results?
On-site mineral testing is same-day. Lab bacteria and chemistry results usually take five to seven business days.
Is water testing part of the membership?
Yes. $49-per-month members receive annual water testing reminders and 10 percent off any related treatment.
How often should a well be tested?
Bacteria once a year and after any flood, well work or change in the water. A full mineral and chemistry test when you buy the property, when you notice staining, smell or scale, and before choosing any treatment equipment.
