Lead Exposure Risk for Children in Farmington

28%
Homes Built Before 1986

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.

While lead results averaged over Farmington ZIP codes come in under 10 micrograms per liter, that figure combines many 90th-percentile values and cannot describe one building, including the 28% of housing that predates 1986.

A/V Share of Claim-Record ZIPs

Historical NFIP data for Farmington contains 14 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $4,762. 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 Farmington

  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. Choose a pitcher or under-sink filter certified to reduce the specific contaminants of concern.
  3. Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
