How Old Is Mount Alto's Housing Stock?
With 55% 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
Reading the housing age data for Mount Alto — median build year 1971 — the overriding implication is that the plumbing materials inside a typical home here reflect pre-1986 construction standards. In practical terms, that means lead-soldered copper joints are common across much of the housing stock. Where those materials are present, water can leach lead as it moves through joints — a pathway that corrosion control treatment under federal rules is designed to reduce, though it cannot eliminate lead risk where the plumbing materials themselves contain lead.
Over half of homes in Mount Alto were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Mount Alto: Remediation Cost in Perspective
In Mount Alto, property values comfortably outpace what documented remediation typically costs — the equity share is proportionally low.
Remediation costs in Mount Alto are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 40% above the West Virginia average.
Protecting Children from Lead in Mount Alto
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 55% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Mount Alto.

What You Can Do in Mount Alto
- 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.
- Install a certified water filter. An NSF-certified pitcher or under-sink filter removes most common contaminants.
- Check your home's plumbing. With 55% of homes built before 1986, lead solder is a real possibility.
- Review your water system's CCR. Your utility publishes an annual Consumer Confidence Report with detailed test results. Request it or find it online.
