How Provo South Compares
Provo South's water is 96% harder than the national average of 138 PPM. It ranks #129 out of 1000 cities in our database (harder than 87% of US cities we track). Within Utah, Provo South has the 2nd hardest water out of 19 cities - 12% above the state average of 241 PPM. Among mid-size cities (100k-200k), Provo South ranks #18 of 189 for hardness. At this hardness level, water heaters run an estimated 50% less efficiently due to scale insulation, and major water-using appliances typically last 4 years less than the national average lifespan.
What Provo South's Water Means for Your Home
Hardness: 270 PPM - Treatment Recommended
Provo South has some extremely hard water. At 270 PPM (15.8 grains per gallon), your tap is loaded with mineral content carried in from the watershed geology. Here's the thing: it's perfectly safe to drink. The minerals won't hurt you. But they will hurt your wallet. That adds up. Hard water at 270 PPM increases household costs through scale-coated water heaters that use more energy, extra soap and detergent, and appliances that wear out faster. Most Provo South homeowners don't realize it until the plumber shows up. That's 12% harder than the Utah average.
Contaminants & Safety
Disinfection byproducts are the notable finding here. Provo South's water has TTHMs at 5.46 ppb and HAA5 at 1.25 ppb — both within legal limits, but the EWG health guidelines are far stricter. These byproducts form when chlorine reacts with organic matter during treatment. A whole-house activated carbon filter reduces both chlorine and its byproducts. Want the full picture? Request your utility's annual Consumer Confidence Report.
What's in the Treatment Process
Chromium-6 was detected at 0.342 ppb, which is 17x the EWG health guideline. There's no separate federal limit for chromium-6, only total chromium. A reverse osmosis system is the most effective removal method. All measurements are within federal legal limits. The EWG guidelines represent a more conservative, health-based standard.
How Hard Water Affects Your Home
At 270 PPM, untreated hard water has measurable effects on household costs and appliance life:
- Water heater inefficiency: Scale insulation forces the heater to work harder (DOE estimates up to 22% more energy for heavily scaled units)
- Soap and detergent: Hard water reduces lathering, requiring significantly more product
- Appliance replacement: Water heaters, dishwashers, and washing machines fail 2-4 years earlier due to scale buildup
- Plumbing maintenance: Scale buildup in pipes reduces flow and requires more frequent service
Note: Impact varies by household size, water usage, and local energy costs. A home water test provides the most accurate assessment for your specific situation.

About Provo South's Water Supply
Water Utility: Provo City Water
Water Source: Provo River + wells (Surface Water)
Population Served: 116,288
Hardness: 270 PPM (15.8 grains per gallon)
Provo South's drinking water comes from surface sources — Provo River + wells. Surface water requires more extensive treatment than groundwater, including coagulation, filtration, and disinfection. This heavier chlorination is why disinfection byproducts tend to be higher in surface-supplied systems. Despite the treatment process, mineral hardness from the watershed carries through. The system serves 116,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Provo City Water's Consumer Confidence Report (CCR) or test your own tap.

Water Softener Sizing for Provo South
At 270 PPM (15.8 GPG), here is how to size a softener for your Provo South home. Multiply hardness in GPG (15.8) by daily water usage (roughly 50 gallons per person). A family of four uses about 200 gallons/day: 15.8 GPG × 200 gal = 3160 grains/day. Over a 7-day regeneration cycle, that is 22,120 grains - a 32,000-grain softener is the right fit for most Provo South households.
