How Old Is Colorado City's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Housing age matters for water quality because lead solder was widely used in plumbing until the 1986 federal ban. Colorado City's median build year of 1995 suggests a majority of homes were constructed under the newer standard — a meaningful factor when assessing household-level lead risk from tap water.
Most homes in Colorado City were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Colorado City: Remediation Cost in Perspective
For most homeowners in Colorado City, the estimated cost of water and safety remediation represents a proportionally modest share of what properties are worth — placing this area in the lower tier of the remediation share scale.
Remediation costs in Colorado City are relatively low compared to home values. The $400–$1,600 estimated range is a small fraction of median property value. Home values are 22% below the Arizona average.
Protecting Children from Lead in Colorado City
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Since the federal solder ban took effect, new plumbing has been built without that pathway, and Colorado City's pre-rule stock at 23% reflects a contained footprint.

What You Can Do in Colorado City
- Test your water at home. City-level data shows averages — your tap may differ. Lead testing is especially recommended given the area's lead levels.
- Install a certified water filter. Filters rated for Total Coliform can reduce the most common contaminant found in Colorado City's water.
- Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
- Review your water system's CCR. Your utility publishes an annual Consumer Confidence Report with detailed test results. Request it or find it online.
