Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Housing & Infrastructure in Friendsville
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
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In Friendsville, the median build year of 1997 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
Most homes in Friendsville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Friendsville Homeowners
At current valuations, Friendsville sits in the low remediation-share tier — the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Friendsville are relatively low compared to home values. The $1,600–$3,300 estimated range is a small fraction of median property value. Home values are 31% above the Tennessee average.
Lead Exposure Risk for Children in Friendsville
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 41% pre-rule share in Friendsville keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

Flood & Climate Risk in Friendsville
Flood risk in Friendsville occupies the middle ground: 1 NFIP claim and 100% of local ZIP codes within FEMA flood zones. At that level, the risk pathways connecting flooding to water quality — treatment system stress, well infiltration, distribution backflow — become relevant considerations during significant flood events, even if day-to-day water quality is unaffected by flood history.
Friendsville has a moderate flood history with 1 FEMA claims averaging $476 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>$2,400</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.
