Riverdale water
Riverdale City provides a blend of its own well water and treated surface water from Weber Basin Water Conservancy District. The city's 2025 report shows no violations across the constituents it tested. Here is what that report lists.
Your water system
Riverdale City Water System
Source: A city well blended with treated surface water purchased from Weber Basin Water Conservancy District (Central system).. Public water system ID UTAH29015.
Riverdale's report does not print a hardness number, but its Weber Basin supply is described district-wide as 10 to 18 grains per gallon.
What stands out
Where it comes from
The report lists Riverdale's sources as the city's #1 Well and Weber Basin Central, so what comes out of your tap is a mix of local groundwater and treated surface water.
Minerals
Total dissolved solids ranged from 324 to 400 ppm, with sodium 25.3 to 39.8 ppm and sulfate 30.0 to 38.3 ppm, all within state limits.
What was tested
Nitrate ranged from 0.40 to 3.05 ppm, under the 10 ppm limit. Disinfection byproducts (total trihalomethanes up to 78.5 ppb against an 80 ppb limit) were reported in compliance on a running-average basis.
This is a plain-language summary, not a substitute for your utility's official report. Riverdale City Water System reports meeting federal drinking-water standards. For the full, current numbers, read the official report linked above.
What helps
What we would do about it.
Given the harder Weber Basin water and a well blend, a salt-free whole-home conditioner plus a drinking-water ionizer is a common choice for Riverdale homes. Stop by The Well for a free water test so you can see your own results before picking anything.
