Mapleton City supplies drinking water from a blend of wells and Maple Canyon springs. The city's 2025 Annual Drinking Water Quality Report shows no violations and states the water meets federal and state requirements. The figures below are pulled from that report.
Your water system
Mapleton City
Source: A mix of groundwater wells and springs in Maple Canyon. The city's report notes these sources have a low susceptibility to contamination.. Public water system ID UTAH25018.
Mapleton's official report does not publish a hardness number, but groundwater in the Hobble Creek and Maple Canyon area is generally on the hard side, which is why scale and spotting are common.
What stands out
Dissolved minerals (TDS)
Mapleton's 2025 report lists total dissolved solids ranging from 180 to 304 ppm (mg/L) across its sources, well under the 2000 ppm secondary limit.
Nitrate and arsenic
Nitrate ranged from 0 to 2.395 mg/L against a 10 mg/L limit, and arsenic from non-detect to 1.2 ppb against a 10 ppb limit. Both stay within federal limits.
Lead and copper
The 90th-percentile lead result was 2.4 ppb (limit 15) and copper 0.15 ppm (limit 1.3), with zero sample sites over the action level.

What helps
What we would do about it.
If you would like smoother, better-tasting drinking water plus less scale on fixtures and appliances, a drinking-water ionizer with whole-home salt-free conditioning is a no-salt path to both. Bring a sample to The Well in Heber City for a free water test and we will recommend what fits your home.
