How Old Is Normandy's Housing Stock?
With 60% 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
Federal plumbing rules changed in two stages — lead pipes were phased out before 1970, and lead solder was banned in 1986 — but in Normandy, where the median build year is 1988, most of the housing was already in place before those rules took effect. The materials installed under older standards remain embedded in a substantial portion of the residential inventory today.
Over half of homes in Normandy were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Normandy: Remediation Cost in Perspective
In Normandy, property values comfortably outpace what documented remediation typically costs — the equity share is proportionally low.
Remediation costs in Normandy are relatively low compared to home values. The $400–$1,600 estimated range is a small fraction of median property value. Home values are 8% above the Tennessee average.
Protecting Children from Lead in Normandy
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.
Wherever 60% of local housing was built before solder rules changed — as is the case in Normandy — a faucet-level sample closes the gap that aggregate utility data cannot.

What You Can Do in Normandy
- 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 60% 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.
