How Old Is Kirby's Housing Stock?
With 95% 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.

Housing Age Profile
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Kirby's median build year of 1979 places it squarely in that category.
Over half of homes in Kirby were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Kirby: Remediation Cost in Perspective
Within the Kirby property market, documented remediation claims a moderate slice of typical equity — real but budgetable.
Remediation costs are moderate relative to home values in Kirby. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 75% below the Wyoming average.
Protecting Children from Lead in Kirby
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 95% pre-rule share in Kirby keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
