Housing Age Profile
If your home in Tolleson predates 1986, testing the tap is the direct way to learn about lead; the median build year of 2005 cannot answer that for you.
Most homes in Tolleson were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Tolleson: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Tolleson contains 241 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $8,815. 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 $900 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 Tolleson
- 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 Surface Water Treatment Rule, listed in the water-quality records for Tolleson: 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.
