Denver Water Quality: What You're Dealing With
Denver and Denver County water is known for high hardness — typically 6–14 grains per gallon. Water source: Denver Water, supplied by mountain snowmelt through the South Platte River watershed and multiple high-elevation reservoirs.
Denver Water is one of the most tested water utilities in Colorado, but its water still contains chloramines, disinfection byproducts, and — in older neighborhoods — potential lead leaching from aging service lines. A reverse osmosis system under the kitchen sink combined with a whole-house carbon filter gives Denver homes the most comprehensive protection.
Common Denver Water Problems
- Variable hardness (6–14 gpg) depending on neighborhood and season
- Chloramine disinfection producing a noticeable chemical taste
- Older Denver infrastructure introducing lead and copper at the tap
- Sediment and particulate matter in aging distribution pipes
- Chlorine disinfection byproducts (THMs and HAAs)
- PFAS compounds detected in some Denver Water samples
