Key Contaminants Detected in Williams
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Williams'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
With a median build year of 1994, Williams'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 Williams were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Williams: Remediation Cost in Perspective
At current valuations, Williams sits in the low remediation-share tier - the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Williams are relatively low compared to home values. The $1,100–$4,100 estimated range is a small fraction of median property value. Home values are 20% above the Arizona average.
Protecting Children from Lead in Williams
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.
When older housing represents 36% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Williams address.

Historical Flood-Claim Evidence for Williams
Historical NFIP data for Williams contains 4 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $13,777. Among ZIP codes with claim records, 0% 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>$2,200</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.
