How Old Is Diana's Housing Stock?
With 42% 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
Plumbing risk in residential housing tracks directly to construction era: pre-1986 homes may have lead-soldered copper joints; pre-1970 homes may have lead pipes outright. Diana's median build year of 1993 places the city in a moderate risk zone where neither era dominates the housing inventory. Understanding which side of the 1986 threshold a specific property falls on — and whether it predates 1970 — is the most actionable starting point for a homeowner trying to assess their own tap water exposure.
Most homes in Diana were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Diana: Remediation Cost in Perspective
Across Diana, the equity share taken up by estimated remediation is small — a favorable ratio for most property owners.
Remediation costs in Diana are relatively low compared to home values. The $300–$800 estimated range is a small fraction of median property value. Home values are 15% above the Texas average.
Protecting Children from Lead in Diana
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.
After the federal action removing lead-bearing solder from new plumbing took effect, building practice shifted — but 42% of the Diana inventory predates that line. With aggregate samples near or beyond 0.015 mg/L, an in-home check moves out of the optional column into the standard list.
