How Old Is Kanawha's Housing Stock?
With 92% 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 a city's housing median build year is 1954, as in Kanawha, the implication for water quality research is straightforward: municipal-level data captures what leaves the treatment plant, but household plumbing from before 1986 determines what actually arrives at the tap. In cities where older housing predominates, that gap between system-level and household-level data is widest.
Over half of homes in Kanawha were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Kanawha: Remediation Cost in Perspective
Viewed from a financial planning lens, Kanawha sits in the moderate remediation-share tier — the equity impact of addressing documented issues is real, and deliberate preparation separates smooth outcomes from disruptive ones for most homeowners.
Remediation costs are moderate relative to home values in Kanawha. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 50% below the Iowa average.
Protecting Children from Lead in Kanawha
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.
When older housing represents 92% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Kanawha address.

What You Can Do in Kanawha
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
