Hobbs vs Roswell Water Quality
Side-by-side water quality comparison for two New Mexico cities.
If you are comparing Hobbs and Roswell water quality - whether moving, choosing between the two, or curious about a relative's water - here is what the data shows.
Hardness comparison
Hobbs has somewhat harder water at 320 PPM versus Roswell at 310 PPM, a difference of 10 PPM. At 320 PPM, Hobbs 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. Roswell also has hard water but to a lesser degree.
Both cities have hard water, but Hobbs's higher hardness means more aggressive scale buildup and higher household impact.
Water sources and why they differ
Water sources differ: Hobbs draws from Ogallala Aquifer, while Roswell uses Roswell Artesian Basin wells. Both use similar source types, but local geology creates the hardness variation.
Contaminant concerns
PFAS contamination is a concern in Hobbs (35.03 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 Roswell to Hobbs, you will notice the water difference. Budget for a water softener and expect to use more soap and detergent until you install one.
