Saint Francis Infrastructure Age
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.

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. Saint Francis's median build year of 1982 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 Saint Francis were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Saint Francis
The equity impact of remediation in Saint Francis sits at a moderate level — real enough to plan for, within reach for most.
Remediation costs are moderate relative to home values in Saint Francis. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 24% below the Kentucky average.
Saint Francis: 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 42% pre-rule share in Saint Francis keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
