How Old Is Hermitage's Housing Stock?
With 41% 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
Over the decades, Hermitage accumulated housing from multiple construction periods. The median build year of 1998 places the midpoint of that stock near the 1986 threshold when lead solder in plumbing became federally prohibited — leaving a sizable share of homes on each side of that safety line.
Most homes in Hermitage were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Hermitage: Remediation Cost in Perspective
How much of a Hermitage home's value does documented remediation represent? A small fraction — the equity share here is in the low tier, and from a household financial perspective, most property owners are considering a commitment that fits comfortably within standard planning rather than a decision that rises to the level of a material budget event or significant equity consideration.
Remediation costs in Hermitage are relatively low compared to home values. The $2,000–$4,000 estimated range is a small fraction of median property value. Home values are 56% above the Tennessee average.
Protecting Children from Lead in Hermitage
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 41% of the Hermitage inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.

Climate-Related Water Risk for Hermitage
FEMA data shows 100% of Hermitage's ZIP codes mapped into designated flood zones, paired with an NFIP record of 101 claims. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Hermitage has a moderate flood history with 101 FEMA claims averaging $23,997 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$3,000</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
