Very HardOld Crow water is very hard at 11.1 GPG (190 ppm). At this hardness a whole-house softener is strongly recommended — hard water here costs the average home roughly $1,365/year.
How we calculate this: based on the Battelle Memorial Institute study commissioned by the Water Quality Association (WQA), hard water is estimated to cost the average affected household roughly $800/year in 2010 dollars (~$1,230 today, after ~54% inflation). We scale that by 11.1 GPG versus a ~10 GPG reference. The percentages above come from the Battelle Memorial Institute study (commissioned by WQRF), the US Department of Energy, and the Water Quality Association. This is an estimate — not a certified per-household figure — and actual savings vary by water use, fuel type, and local rates.

Why Is Old Crow Water So Hard?
Old Crow sits on a bed of ancient limestone and dolomite, and that geology is the whole story behind your 11.1 GPG reading. The community draws its water from groundwater wells, and every drop of that well water has to travel through layers of carbonate rock before it ever reaches a tap. Rain and snowmelt soak into the ground, pick up carbon dioxide from the soil, and turn into a weak carbonic acid. That mild acid then chews through the calcium and magnesium carbonate in the limestone as it moves underground. The result is water that’s loaded with dissolved hardness minerals by the time it’s pumped out of the ground. The Yukon’s permafrost and glacial history play a role here too. The freeze-thaw cycles and the grinding action of ancient glaciers fractured the bedrock, creating more surface area for groundwater to contact. More contact means more dissolution. That’s why Old Crow’s wells pull up water that measures 11.1 GPG, which puts it squarely in the “very hard” category. For context, the USGS classifies anything above 10.5 GPG as very hard, and the national average in the US is about 7.3 GPG. You’re running roughly 50 percent above that average, and it’s not an accident of treatment. It’s the rock itself. One thing worth understanding: hardness here isn’t a contamination problem. The EPA doesn’t regulate hardness as a health hazard at all. It’s purely an aesthetic and nuisance issue, which is why it falls under Secondary Maximum Contaminant Levels. But nuisance doesn’t mean harmless to your plumbing. That same dissolved calcium and magnesium that makes your water taste minerally is the stuff that coats your water heater elements and clogs your showerheads. ## How Old Crow Compares to Nearby Cities
Old Crow is the only community in the Yukon north of the Arctic Circle, so the comparison pool is thin. The nearest settlements of any size are Inuvik in the Northwest Territories and Fort Yukon in Alaska, and both draw from different water systems entirely. Inuvik pulls its water from the Mackenzie River, which is a surface source fed by glacial runoff and snowmelt. River water like that typically carries far less dissolved hardness than groundwater, because it hasn’t had the same extended contact time with carbonate bedrock. So if you’ve ever filled a glass in Inuvik and noticed it tastes cleaner, you’re not imagining it. That’s the difference between surface water and well water. Fort Yukon, downriver on the Yukon River, is a similar story. The river itself picks up some minerals as it winds through the interior, but it’s still a surface source. It doesn’t sit in contact with limestone the way Old Crow’s groundwater does. The practical effect is that Old Crow residents deal with scale buildup faster and need more soap and detergent than folks in those river-fed communities. The WQA and Battelle found in a 2010 study that soft water can cut laundry detergent use by up to 50 percent and dish soap by up to 70 percent. That’s the kind of difference you’d notice between Old Crow’s wells and a river-fed system. That said, the Vuntut Gwitchin First Nation operates the local well system, and the water quality is consistent year-round. River communities can see hardness fluctuate with spring melt and summer flows. Groundwater doesn’t swing that way. So while Old Crow’s water is harder, it’s also more predictable. You know what you’re getting every day, and that consistency makes it easier to set your water treatment properly. The tradeoff is real, but it’s not a mystery. The limestone under Old Crow is doing exactly what limestone does, and it’s been doing it for thousands of years.

What 11.1 GPG Actually Does to an Old Crow Home
At 11.1 GPG (190 ppm), Old Crow water is +71% harder than the Canadian national average — and the damage shows up everywhere:
- Water heaters fail early. The Battelle Memorial Institute study found very-hard-water heaters failed in under 2 years, while softened-water units lasted the full 10-year test period. That's appliance life being burned through at 5× speed.
- Energy waste. Scale insulates the heating element, forcing the unit to work up to 9% harder — a direct, recurring cost on every bill.
- Constant descaling. Showerheads clog, faucet aerators crust over, and glassware never looks clean without a rinse aid.
- Up to 75% more detergent. Per the Water Quality Association, hard water sharply reduces soap effectiveness, and mineral residue roughs up fabric fibers, wearing clothes faster.
This isn't cosmetic. It's equipment and energy cost, quantified — at 11.1 GPG the running total is roughly $1,365 per year for an average 3–4 person home (see the calculator above — adjust the household size to see your number).
Do You Need a Water Softener in Old Crow?
Yes — this is close to a non-negotiable. At 11.1 GPG, Old Crow homeowners don't really debate whether to treat; they debate which system. The annual hard-water cost here is around $1,365, so a quality softener (~$1,000 installed) typically recovers its cost in well under a year.
Salt-free conditioners won't cut it at 11.1 GPG — they reduce scale but can't remove the minerals causing the soap, skin, and appliance problems. You need ion exchange. Size the unit to your household: a 32,000–48,000-grain softener handles a typical 3–4 person home at this hardness.
What Size Softener Does Old Crow Need?
Sizing a softener is a two-number equation: your household's daily water use × your hardness. The rule of thumb is grains per day = (people) × (75 gallons) × (GPG).
- At 11.1 GPG, a family of four uses roughly 3,330 grains of hardness per day.
- A 32,000–48,000-grain softener regenerates roughly every 8–12 days — within the 3–7 day window that keeps salt and water use efficient.
- Round up, not down: an undersized unit regenerates too often and wastes salt. Metered (on-demand) regeneration saves the most salt and water.
For Old Crow at 11.1 GPG, a 32,000–48,000-grain metered softener is the safe default for a 3–4 person home. A larger household, or one with unusually high water use, should size up to 64,000 grains.
What Are the Signs of Hard Water in a Old Crow Home?
At 11.1 GPG (190 ppm), Old Crow residents notice significant hard-water effects. The USGS classifies water above 7 GPG as hard and notes it causes measurable physical damage to plumbing and appliances.
- White or grey crust on faucet aerators, showerheads, and around drains — calcium carbonate depositing as water evaporates.
- Spotty glassware even after a full dishwasher cycle — mineral film left behind when water dries.
- Falling water-heater efficiency — scale insulates the heating element, forcing the unit to work harder and pushing up the energy bill.
- Flat, stiff hair — calcium bonds to hair proteins and prevents shampoo from rinsing clean.
- Dry, itchy skin — dissolved minerals disrupt the skin's moisture barrier.
- Weak soap lather — hardness ions react with soap to form insoluble scum instead of suds.
- Shorter appliance life — washing machines, dishwashers, and coffee makers accumulate internal scale.
The Battelle Memorial Institute study commissioned by the Water Quality Research Foundation found untreated very-hard-water heaters failed in under 2 years, versus a full 10 years on softened water. At Old Crow's 11.1 GPG, that equipment degradation compounds faster than most homeowners expect.

How Do You Test Water Hardness in Old Crow?
This page reports Old Crow's system-wide average (11.1 GPG), but your tap can vary slightly by neighborhood, pipe age, and in-home filtration. For a step-by-step, see how to test your water hardness at home — it walks through test strips, the free soap-shake check, TDS meters, titration kits, and certified lab tests.
- Test strips (~$10) give a GPG reading in about 30 seconds and are accurate enough to decide whether to invest in treatment.
- TDS meter (~$15) measures total dissolved solids, a rough hardness proxy — but it doesn't separate hardness from other minerals.
- Lab test — most water treatment companies in Old Crow offer free in-home tests (expect a sales pitch); for an independent result, the EPA maintains a list of certified labs.
Note: the EPA doesn't regulate hardness (it's a nuisance, not a health hazard), but the EWG Tap Water Database tracks contaminants above health guidelines for Old Crow's utility — see the table below.

Based on the WQA-commissioned Battelle Memorial Institute study, hard water is estimated to cost the average affected household roughly $800/year in 2010 dollars (~$1,230 today after ~54% inflation) — an estimate, not a measured per-household figure. Scaled to Old Crow's 11.1 GPG hardness, that works out to about $1,365/year (or ~$113.75/month) for a typical home — see the calculator on this page for the full breakdown.
Does Old Crow need a water softener?
Yes — at 11.1 GPG, a whole-house water softener is the most effective way to prevent scale buildup, protect appliances, and reduce soap scum.
Why is Old Crow's water hard?
Hardness comes from the geology of Old Crow's water source. Groundwater (well system) dissolves calcium and magnesium as water moves through the ground, and those dissolved minerals are what "hard water" means.
How do I test my water hardness in Old Crow?
Use a home test kit (test strips for a quick read, or a TDS meter for dissolved solids), or check your utility's annual Consumer Confidence Report (CCR). For lab-accurate results, send a sample to a certified lab.
Who supplies Old Crow's water?
Old Crow water is supplied by Vuntut Gwitchin First Nation. Its annual water quality report (Consumer Confidence Report) is the authoritative source for local hardness and contaminant levels.
What's the difference between grains per gallon and ppm?
1 GPG (grains per gallon) equals 17.1 ppm (mg/L). To convert: 11.1 GPG × 17.1 = ~190 ppm. Water is "hard" above roughly 7 GPG (120 ppm).
