Source: Groundwater from two wells and one spring, listed in the report as Icy Spring, Hoytsville Well, and Lewis Hollow Well.. Public water system ID UTAH22002.
Coalville's official report does not list a hardness number, but the higher dissolved-mineral readings across its sources suggest noticeably mineralized water, which often shows up as scale and spotting.
What stands out
Dissolved minerals (TDS)
Coalville's 2025 report shows total dissolved solids ranging from 248 to 888 ppm (mg/L) across its sources. That is still under the 2000 ppm secondary limit, though the higher end reflects more mineralized groundwater you may taste.
Nitrate and fluoride
Nitrate ranged from 0 to 2.262 mg/L against a 10 mg/L limit, and fluoride from 0.139 to 0.237 ppm against a 4 ppm limit. Both are within federal limits.
Lead and copper
The 90th-percentile lead result was 2.1 ppb (limit 15) and copper 0.622 ppm (limit 1.3), with zero sample sites over the action level.
