What's in Scottsdale's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Scottsdale Infrastructure Age
With 41% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
With a median build year of 1987, Scottsdale's housing stock reflects a city built across multiple eras. A substantial share of homes predate 1986 - the year lead solder in plumbing was federally banned - meaning the risk from plumbing materials is unevenly distributed across the city's neighborhoods and property types.
Most homes in Scottsdale were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Scottsdale
Because property values in Scottsdale comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Scottsdale are relatively low compared to home values. The $1,073–$3,573 estimated range is a small fraction of median property value. Home values are 130% above the Arizona average.
Scottsdale: Lead Risk & Vulnerable Populations
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Older stock in Scottsdale represents 41% of the inventory, and citywide monitoring runs at or above the federal action level - making an in-home read a standard household-level step.
Sources: EPA Lead and Copper Rule, U.S. Census Bureau ACS, CDC childhood lead poisoning prevention guidelines.
Scottsdale: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Scottsdale contains 360 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $16,040. Among ZIP codes with claim records, 18% 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 <strong>$2,113</strong> 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.
