Housing Age Profile
For Gilbert, the median build year stands at 2002; the figures below show the share of homes from each era.
Most homes in Gilbert were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Gilbert: Lead Risk & Vulnerable Populations
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.
For families with young children in Gilbert, two area figures are available: pre-1986 construction at about 10%, and a mean of the ZIP codes' 90th-percentile lead results under 0.010 mg/L. Testing water from the tap a child drinks from gives a home-specific result.
Sources: EPA Lead and Copper Rule, U.S. Census Bureau ACS, CDC childhood lead poisoning prevention guidelines.
Gilbert: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Gilbert contains 21 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $10,116. Among ZIP codes with claim records, 17% 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 $629 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.
Source: historical FEMA National Flood Insurance Program (NFIP) claim records. No current FEMA property-map designation is asserted.
What You Can Do in Gilbert
- 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. For Arsenic, listed in the water-quality records for Gilbert: 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.
- 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.
