Key Contaminants Detected in Avondale
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Avondale'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
Whether your home in Avondale was built before or after 1986 matters more than the citywide median of 2008, because the 1986 federal lead restrictions cover plumbing installed after that point.
Most homes in Avondale were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Avondale: Remediation Cost in Perspective
Because the median home value in Avondale is large relative to the estimated cost of remediation, the ratio between them stays at or below 1%; that is a statement about two area-level numbers, not a quote for a particular house or a judgment about what an owner can pay.
Estimated remediation costs in Avondale can be compared with local home values. The $475–$1,100 estimated range can be set against the median property value; actual costs vary by home. Home values are 19% above the Arizona average.
Protecting Children from Lead in Avondale
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.
Pre-1986 construction accounts for about 16% of Avondale homes; older plumbing in any of them can still add lead at the tap.

Historical Flood-Claim Evidence for Avondale
Historical NFIP data for Avondale contains 12 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $9,577. 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 $750 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 Avondale
- 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 Chlorine, listed in the water-quality records for Avondale: 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.
