Swift Current's water has Total Trihalomethanes (THMs) above the Health Canada legal limit. See the breakdown below and consider a filter rated for that contaminant.
What's in Swift Current's water
Detected contaminants reported for City of Swift Current Water Treatment.

Total Trihalomethanes (THMs) exceeds the Health Canada legal limit. This is worth investigating — a filter rated for that contaminant may be appropriate.
How to read this table: the legal limit (Health Canada's Maximum Acceptable Concentration (MAC)) is the enforceable safety line — it's what regulators actually require. A contaminant above its aesthetic guideline (like iron or sodium) affects taste or staining — not your health.
| Contaminant | Typical level | Health Canada limit | Status |
|---|---|---|---|
| Arsenic | 0.0005 mg/L | 0.01 mg/L | Below limit |
| Barium | 0.037 mg/L | 1 mg/L | Below limit |
| Boron | 0.04 mg/L | 5 mg/L | Below limit |
| Cadmium | — mg/L | 0.005 mg/L | Below limit |
| Chromium | — mg/L | 0.05 mg/L | Below limit |
| Fluoride | 0.53 mg/L | 1.5 mg/L | Below limit |
| Lead | — mg/L | 0.01 mg/L | Below limit |
| Nitrate | — mg/L | 45 mg/L | Below limit |
| Selenium | 0.0004 mg/L | 0.01 mg/L | Below limit |
| Uranium | — mg/L | 0.02 mg/L | Below limit |
| Total Trihalomethanes (THMs) | 0.11 mg/L | 0.1 mg/L | Above limit |
| Sodium | 83 mg/L | 200 mg/L | Below limit |
| Sulphate | 327 mg/L | 500 mg/L | Below limit |
Levels are typical (median) municipal test results. The legal limit is Health Canada's Maximum Acceptable Concentration (MAC).

What actually matters in Swift Current's water
Most of the numbers in the table are below the legal limit and aren't worth your worry. Here's the honest read on the ones people actually ask about in Swift Current:
Why the limit exists: There is no safe level of lead. It is a developmental neurotoxin — even low exposure is linked to delays in children's physical and mental development and attention deficits, and to kidney problems and high blood pressure in adults.
Who it matters most for: Children (especially under 6) and pregnant women.
Source: EPA AL / HC MAC
Why the limit exists: Arsenic is a Group 1 human carcinogen (IARC). The limit is based on increased risk of bladder, lung, and skin cancer, plus skin damage and circulatory problems at elevated long-term exposure.
Source: EPA MCL / HC MAC
Why the limit exists: The limit protects infants from "blue baby syndrome" (methemoglobinemia). Infants under six months convert nitrate to nitrite and lack the enzyme to reverse it, so their blood can't carry oxygen. Cases occur above 10 mg/L, not at or below.
Who it matters most for: Infants under 6 months (especially formula-fed).
Source: EPA MCL / HC MAC
Why the limit exists: Trihalomethanes are disinfection byproducts. Long-term exposure above the limit is associated with liver, kidney, and central nervous system problems plus an increased risk of cancer (most consistently bladder). The limit is a deliberate trade-off: you can't remove them without abandoning disinfection, which would risk far worse microbial disease.
Source: EPA MCL / HC MAC
Why the limit exists: Chromium-6 (the hexavalent form) is a known carcinogen when inhaled and is associated with stomach and intestinal tumors in drinking-water studies; the total-chromium MCL covers all forms. The basis is allergic dermatitis plus the cancer concern from the hexavalent form.
Source: EPA MCL
Why the limit exists: Uranium is both a kidney toxin and a weak alpha-emitter (radioactive); the limit is set for kidney toxicity and the associated increased cancer risk from long-term exposure.
Source: EPA MCL / HC MAC
Why the limit exists: Barium at elevated levels can increase blood pressure and affect the cardiovascular system; the limit is set for those effects from long-term exposure.
Source: EPA MCL / HC MAC
Why the limit exists: Fluoride is added to protect teeth, but above the limit it can cause bone disease (pain and tenderness) and mottled teeth in children. This is a "protecting from excess" limit, not a "removing a poison" limit.
Who it matters most for: Children (tooth mottling at high exposure).
Source: EPA MCL / HC MAC
Why the limit exists: Boron at elevated levels is associated with reproductive and developmental effects in animal studies; the advisory is precautionary. It is rarely near concern in treated municipal water.
Source: EPA HRL / HC
Why the limit exists: Cadmium is linked to kidney damage and is a probable carcinogen; the limit is set for kidney toxicity from long-term exposure.
Source: EPA MCL / HC MAC
Why the limit exists: Selenium at elevated levels can cause hair and fingernail loss, numbness in fingers or toes, and circulatory problems.
Source: EPA MCL / HC MAC
Why the limit exists: Sodium above the objective affects TASTE (salty) — it is not a health hazard for most people. The limit exists for palatability and as a signal for people on very low-sodium diets.
This is an aesthetic measure — not a health hazard.
Source: HC AO / EPA SMCL
Why the limit exists: Sulphate above the objective can cause a bitter/medicinal taste and a laxative effect in some people; it is an aesthetic/palatability limit, not a health limit.
This is an aesthetic measure — not a health hazard.

Where Swift Current's water comes from — and how it's treated
Duncairn Dam (Swift Current Creek)
Like every Canadian municipal supply, Swift Current's water is disinfected (typically chlorine or chloramine) and monitored against Health Canada's Guidelines for Canadian Drinking Water Quality, enforced provincially. If you want to read the raw report for yourself, our how to read your water quality report guide walks you through it line by line.
Water quality vs. water hardness — don't confuse the two
"Water quality" (is it safe to drink) and "water hardness" (how much scale it leaves) are entirely different things — and confusing them leads to bad purchases. Swift Current's water is very hard (21.7 GPG), which has no bearing on its safety — hardness is a cosmetic and appliance concern, not a health one. For what that hardness costs you in scale, appliance wear, and water-heater efficiency, see the Swift Current water hardness page.
If contaminants concern you — add a drinking-water filter
Should you filter Swift Current's water?
The softener handles hardness; a drinking-water filter removes Arsenic and removes Lead — if Swift Current's reported levels concern you. EPA: Arsenic is a known human carcinogen (skin, lung, bladder cancer) and, at exposure, is also linked to cardiovascular disease and developmental effects. EPA MCL: 10 ppb. EPA / CDC: There is no safe level of lead, and it is especially harmful to children (developmental and neurological damage). EPA action level: 15 ppb at the tap. For a full breakdown of what each filter type removes, see best whole-house water filters.

When to call a professional
Swift Current's water has Total Trihalomethanes (THMs) above the legal limit, so this is the one case where having a professional look at your tap — not just the city-wide average — is genuinely worth it. A licensed water-treatment specialist can test your home's water specifically, confirm whether your plumbing is contributing anything extra, and recommend a correctly-rated filter (for PFAS, a point-of-use reverse-osmosis or granular-activated-carbon system, for example).
Certified, independent results come from a state/province-licensed lab, not a company with a sales incentive — ask for a lab that reports to Health Canada or your province.

Where does Swift Current drinking water come from?
Duncairn Dam (Swift Current Creek)
Should I filter Swift Current's tap water?
Yes — a filter rated for the specific contaminant(s) above the limit is worth considering. See the full breakdown for which one matters.
Is Swift Current water hard?
Swift Current water is very hard at 21.7 GPG (371 ppm). Hardness is separate from safety — it affects scale and appliances, not health. See the Swift Current water hardness page for the full picture.
