What's in Franklin's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Franklin Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Congress banned lead solder in residential plumbing in 1986, drawing a clear line in housing risk by era. Franklin's median build year of 1999 puts most of its residential stock on the newer side of that boundary — a profile that generally correlates with lower plumbing-sourced lead exposure across the city.
Most homes in Franklin were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Franklin
In Franklin, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.
Remediation costs in Franklin are relatively low compared to home values. The $2,160–$5,340 estimated range is a small fraction of median property value. Home values are 207% above the Tennessee average.
Franklin: Lead Risk & Vulnerable Populations
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.
Confirming what flows from a specific faucet still requires a one-home draw, even where Franklin averages stay clean and the pre-rule housing share holds at 27%.

Franklin: Flood History & Water Damage Risk
Substantially more flood exposure than most communities appears in Franklin's NFIP record — 585 documented claims and 80% of ZIP codes in FEMA flood zones. That exposure level makes the water-quality implications of flooding an active planning consideration rather than a background one.
Franklin has a significant flood history with 585 FEMA flood insurance claims on record, averaging $22,828 per claim. With 80% of ZIP codes in FEMA-designated flood zones, flood risk is a major concern for homeowners and water quality.
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>$3,420</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.

What You Can Do in Franklin
- 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. Filters rated for Haloacetic Acids (HAA5) can reduce the most common contaminant found in Franklin's water.
- Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
- Review your water system's CCR. Your utility publishes an annual Consumer Confidence Report with detailed test results. Request it or find it online.
