How hard is the water in Baca County, CO?
15.8 grains per gallon
A softener will pay its way here.
The median hardness measured in Baca County, CO is 270 mg/L as calcium carbonate, which is 15.8 gpg. That is very hard on the USGS scale. It comes from 84 samples at 23 sites between 1993 and 2026, drawn from every sampling site in the county, wells and surface water together.
How much it varies here
Half the sites came in between 12.4 and 20.7 gpg. The whole middle of that range gives the same answer, so a test of your own tap is unlikely to change it. Confidence in the county figure: high (how it is measured).
What to do next
At 15.8 gpg a softener pays its way here. Before you buy, check the quoted unit's grain capacity against the sizing table below, and ask whether it regenerates on demand, which uses less salt than a timer. Call your utility for its own report if you are on city water.

From 4.7 to 57.2 gpg
The softest single sample on record in Baca County was 80 mg/L and the hardest 980 mg/L, a 12-fold gap. The top quarter of sites read above 20.7 gpg and the bottom quarter below 12.4 gpg.
Wells 11.9 gpg, rivers and lakes 15.8 gpg
3 groundwater samples from 3 wells put the median at 204 mg/L. 81 surface samples from 20 sites put it at 270 mg/L. In Baca County the rivers and lakes come out 3.9 gpg harder. Here the surface water reads harder than the wells, which often points to streams fed by limestone springs or irrigation return flow. A utility here that draws from the aquifer can deliver noticeably different water from a private well next door.
What a softener would cost to run
For a household of 3, a 24,000-grain unit covers a week between regenerations. Expect about 344 lb of salt a year (9 bags of 40 lb, about $62), and roughly 2,346 gallons of regeneration water. Installed, most units run $1,000 to $4,500; spread over 15 years with salt, that is about $162 a year.
