Ross River Water Is Very Hard — Here's What It Costs You Each Year

Why Is Ross River Water So Hard?

Ross River sits on the Canadian Shield, one of the oldest rock formations on the planet. That sounds like it should mean soft water, but it’s the opposite. The town’s water comes from groundwater wells, and that’s the whole story. Rain and snowmelt soak down through the soil and into the fractured bedrock below. Along the way, the water picks up carbon dioxide from the organic matter in the ground, which turns it slightly acidic. That weak acid then dissolves the calcium and magnesium carbonate minerals in the rock. It’s a slow process, but the water here has had thousands of years to work on it. By the time it reaches the well pumps, it’s carrying a heavy load of dissolved minerals. The result is water measuring 16.6 GPG, or 283 parts per million. That puts Ross River firmly in the “very hard” category, which the USGS defines as anything above 10.5 GPG. For context, the USGS says the national average is around 7.3 GPG, and roughly 85% of American households already have hard water. Ross River is running at more than double the national average. You’re not imagining it if your soap doesn’t lather and your kettle furs up fast. That’s the geology talking. The Yukon’s permafrost and thin soil layer don’t help either. With less soil to filter and buffer the water, the groundwater stays in direct contact with the bedrock longer. Every well in the area taps into this same mineral-rich source. The water doesn’t get a chance to soften before it reaches your tap. It comes out of the ground already loaded with hardness, and nothing in the treatment process removes it because hardness isn’t a regulated contaminant. The EPA treats it as an aesthetic issue only, governed by a Secondary Maximum Contaminant Level rather than a health standard. ## How Ross River Compares to Nearby Cities

Ross River Dena operates the local well system, and that’s the key to understanding how the town compares to its neighbors. The water here comes from groundwater, not from the Pelly River that runs alongside the community. That distinction matters. Communities that draw from the river itself are pulling surface water, which typically has lower mineral content because it hasn’t spent years dissolving bedrock. Ross River’s wells, by contrast, pull from the same fractured shield geology that makes the local groundwater consistently hard. Nearby communities in the Yukon that rely on surface water sources, like those drawing from the Yukon River system, generally see softer water. That’s not a guess about their specific numbers; it’s just the basic difference between surface and groundwater. Rivers carry suspended sediment but far fewer dissolved calcium and magnesium ions. Wells drilled into carbonate-bearing rock, like the ones serving Ross River, are a different animal entirely. The practical comparison for residents is this: if you’ve lived in a river-supplied community and moved to Ross River, the difference in your shower and your laundry will be obvious. Research from the WQA and Battelle Memorial Institute found that soft water can cut laundry detergent use by up to 50% and dish soap by up to 70%. That’s the kind of gap you’d notice between a surface-water town and a hard-rock well town like this one. The costs add up too. Based on the WQA-commissioned Battelle Memorial Institute study, hard water is estimated to cost the average affected household more each year in extra energy, premature appliance wear, and additional cleaning products — see the cost calculator on this page for the number scaled to this city’s actual hardness. Battelle’s 2009 research found roughly 4% efficiency loss in gas water heaters for every 5 GPG of hardness at a 50-gallon-per-day household. At 16.6 GPG, that’s a serious drag on your energy bill. The DOE adds that just a quarter inch of scale can cut water heater efficiency by up to 40%. And the WQRF notes hard water shortens water heater service life by roughly 30-50%. Ross River’s water is on the high end of what you’ll find in the territory, and it’s the wells, not the river, that make it that way.

How does Ross River stack up against the rest of Yukon? It's very hard at 16.6 GPG — Haines Junction, Mayo, and Burwash Landing sit nearby with different numbers. See the full hardest-water ranking for context.
