Lead Exposure Risk for Children in Florence

0.0022
mg/L average of reported water-system 90th-percentile lead results (the 0.015 action level applies to each system's result, not to this average)

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.

Available area-level lead records for Florence do not determine the lead level at an individual tap. Testing is the only way to confirm your water's lead content.

A/V Share of Claim-Record ZIPs

Historical NFIP data for Florence contains 4 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $23,768. Among ZIP codes with claim records, 0% 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 $1,200 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 Florence

  1. 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.
  2. Install a certified water filter. For Revised Total Coliform Rule, listed in the water-quality records for Florence: if it is a rule or reporting requirement rather than a contaminant, ask your utility what the record involved; for bacteria, follow any boil-water notice from your utility; for a specific chemical contaminant, check whether a filter is certified to reduce it. Not every contaminant has a consumer filter certification.
  3. Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
  4. 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.
