What this means for your home

Denver is inside Lincoln County WTP's service area on the state's water-system map.

Lincoln County WTP's report doesn't list hardness. Most reservoir-fed systems in this region are soft, but a quick hardness test at your tap is the only way to know before anyone recommends a softener.
Lincoln County Water System (Lincoln County WTP) disinfects with free chlorine. If you notice the taste or smell, NSF/ANSI 42 certified carbon reduces it.
Disinfection byproducts (TTHM) were 60 ppb against an 80 ppb limit. That's compliant; some households still prefer a margin, which NSF/ANSI 53 carbon or reverse osmosis provides.
39.5% of homes in Denver were built before 1980. EPA notes homes built before 1986 are more likely to have lead in their plumbing, so a certified-lab lead test at the tap is a sensible first step in an older home.
