How Old Is Crystal City's Housing Stock?
With 72% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
The median home in Crystal City was built in 1963 - 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 Crystal City were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Crystal City: Remediation Cost in Perspective
Within the Crystal City property market, documented remediation claims a moderate slice of typical equity - real but budgetable.
Remediation costs are moderate relative to home values in Crystal City. The estimated $1,400–$4,900 range is manageable for most homeowners but still worth budgeting for. Home values are 3% below the Missouri average.
Protecting Children from Lead in Crystal 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.
Confirming what arrives at a specific faucet is something utility-side averages cannot do. With 72% of Crystal City stock built before the lead-solder ban and citywide monitoring at or beyond the regulatory mark, a tap-level kit fits the standard diligence picture.
