How Old Is Powell's Housing Stock?
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
Remodels change the picture: a 1993 median in Powell says nothing about pipes swapped out or repaired since construction.
Most homes in Powell were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Powell: Remediation Cost in Perspective
Relative to home values, Powell remediation estimates run low.
Estimated remediation costs in Powell can be compared with local home values. The $300–$800 estimated range can be set against the median property value; actual costs vary by home. Home values are 146% above the Ohio average.
Protecting Children from Lead in Powell
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
No safe blood lead level in children has been identified, according to CDC, so an area average under 0.010 mg/L does not rule out exposure at home. In Powell, 25% of homes were built before 1986.
Sources: EPA Lead and Copper Rule, U.S. Census Bureau ACS, CDC childhood lead poisoning prevention guidelines.
Historical Flood-Claim Evidence for Powell
Historical NFIP data for Powell contains 32 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $14,636. Among ZIP codes with claim records, 100% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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. The $500 remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.

What You Can Do in Powell
- Test your water at home. City-level data shows averages - your tap may differ. Check the certification, price and turnaround time of any water test kit or lab service.
- Install a certified water filter. Choose a pitcher or under-sink filter certified to reduce the specific contaminants of concern.
- 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. If you use a community water system, request its annual Consumer Confidence Report for system-level test results or find it online.
