Housing Age Profile

The median home in Colo was built in 1952 - a figure that places most of the city's residential stock in the era when lead solder was still standard in copper plumbing. Homes built before 1986 may have lead-soldered joints; those built before 1970 face the additional possibility of lead pipes in the service line itself.

Over half of homes in Colo were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Lead Exposure Risk for Children in Colo

82%
Homes Built Before 1986

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.

In recent monitoring under the Lead and Copper Rule, citywide samples for Colo have approached or crossed the regulatory action level on multiple occasions. Combined with 82% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.
