Housing Age Profile
The story of Caulfield's housing stock is one of layered development — neighborhoods built in different decades, each carrying the plumbing standards of their era. The median build year of 1982 reflects that layered character. Before 1986, lead solder was standard in copper plumbing; before 1970, lead pipes were commonly used for service lines. A substantial portion of the pre-1986 homes visible in the distribution above still carry the plumbing materials of those earlier standards — creating a risk environment that the city-wide aggregate water data doesn't fully capture.
Most homes in Caulfield were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Caulfield
In Caulfield, the equity impact of remediation is proportionally small — not the kind of financial commitment that rises to the level of a genuine planning constraint, but a minor share of what most properties here are worth.
Remediation costs in Caulfield are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 9% above the Missouri average.
Caulfield: Lead Risk & Vulnerable Populations
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 49% pre-rule share in Caulfield keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
