Roswell vs Clovis Water Quality

Side-by-side water quality comparison for two New Mexico cities.

If you are comparing Roswell and Clovis water quality - whether moving, choosing between the two, or curious about a relative's water - here is what the data shows.

Hardness comparison

Roswell has somewhat harder water at 310 PPM versus Clovis at 300 PPM, a difference of 10 PPM. At 310 PPM, Roswell residents should budget for a water softener ($600-$1,500 installed). Without one, expect scale buildup on fixtures, reduced water heater efficiency, and $800-$1,200/year in hidden costs. Clovis also has hard water but to a lesser degree.

Both cities have hard water, but Roswell's higher hardness means more aggressive scale buildup and higher household impact.

Water sources and why they differ

Water sources differ: Roswell draws from Roswell Artesian Basin wells, while Clovis uses Ogallala Aquifer. Both use similar source types, but local geology creates the hardness variation.

Contaminant concerns

PFAS contamination is a concern in Clovis (4.3 ppt, above the EPA limit of 4 ppt). A reverse osmosis system or NSF P473-certified filter is recommended for drinking water.

What this means for you

If you are moving from Clovis to Roswell, you will notice the water difference. Budget for a water softener and expect to use more soap and detergent until you install one.
