Is Fremont, NE Tap Water Safe to Drink?
Yes, Fremont tap water is safe to drink. No contaminants exceed health guidelines. However, Fremont has very hard water at 265 PPM, which will cause scale buildup in plumbing and appliances over time. A water softener is worth considering.

How Fremont Compares
Fremont's water is 92% harder than the national average of 138 PPM. It ranks #138 out of 1000 cities in our database (harder than 86% of US cities we track). Within Nebraska, it ranks #5 of 10 cities (7% above the state average of 248 PPM). Among smaller cities, Fremont ranks #46 of 288 for hardness. At this hardness level, water heaters run an estimated 49% less efficiently due to scale insulation, and major water-using appliances typically last 4 years less than the national average lifespan.
What Fremont's Water Means for Your Home
Hardness: 265 PPM - Treatment Recommended
Fremont has some extremely hard water. At 265 PPM (15.5 grains per gallon), your tap is loaded with dissolved calcium and magnesium picked up from underground limestone and dolomite formations. 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 265 PPM increases household costs through scale-coated water heaters that use more energy, extra soap and detergent, and appliances that wear out faster. Most Fremont homeowners don't realize it until the plumber shows up. That's 7% harder than the Nebraska average.
Contaminants & Safety
Disinfection byproducts are the notable finding here. Fremont's water has TTHMs at 20.6 ppb and HAA5 at 12.6 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
Even though Fremont draws from groundwater, the treatment process still generates disinfection byproducts: TTHMs at 20.6 ppb and HAA5 at 12.6 ppb. Groundwater typically needs less treatment than surface water, but when organic compounds are present in the aquifer, chlorination creates the same byproducts. All levels are within legal limits, though above the stricter EWG health guidelines.
Chromium-6 is naturally present in Fremont's aquifer geology at 0.0535 ppb — 2.7x the EWG health guideline. There's no federal legal limit for chromium-6 specifically (only total chromium), which is why EWG tracks it separately. All measurements are within federal legal limits. The EWG guidelines represent a more conservative, health-based standard.
How Hard Water Affects Your Home
At 265 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 Fremont's Water Supply
Water Utility: City of Fremont Water
Water Source: Platte River alluvial wells (Groundwater)
Population Served: 27,230
Hardness: 265 PPM (15.5 grains per gallon)
Fremont draws its drinking water from groundwater sources — Platte River alluvial wells. Groundwater typically requires less treatment than surface water because the earth acts as a natural filter. The tradeoff: dissolved minerals from underground rock formations, which is why hardness is elevated here. Calcium and magnesium dissolve into the water as it moves through limestone and dolomite. The system serves 27,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request City of Fremont Water's Consumer Confidence Report (CCR) or test your own tap.

Water Softener Sizing for Fremont
At 265 PPM (15.5 GPG), here is how to size a softener for your Fremont home. Multiply hardness in GPG (15.5) by daily water usage (roughly 50 gallons per person). A family of four uses about 200 gallons/day: 15.5 GPG × 200 gal = 3100 grains/day. Over a 7-day regeneration cycle, that is 21,700 grains - a 32,000-grain softener is the right fit for most Fremont households.
