What's in Tolleson's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Tolleson Infrastructure Age
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
Congress banned lead solder in residential plumbing in 1986, drawing a clear line in housing risk by era. Tolleson's median build year of 2005 puts most of its residential stock on the newer side of that boundary — a profile that generally correlates with lower plumbing-sourced lead exposure across the city.
Most homes in Tolleson were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Tolleson
At current valuations, Tolleson sits in the low remediation-share tier — the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Tolleson are relatively low compared to home values. The $1,200–$3,400 estimated range is a small fraction of median property value. Home values are 13% above the Arizona average.
Tolleson: 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.
Confirming what flows from a specific faucet still requires a one-home draw, even where Tolleson averages stay clean and the pre-rule housing share holds at 14%.

Tolleson: Flood History & Water Damage Risk
100% of ZIP codes in Tolleson are mapped into FEMA-designated flood zones, and the NFIP records 240 claims reflecting a multi-event flood history. That combination places local flood exposure in the range where water-quality implications deserve at least periodic attention.
Tolleson has a moderate flood history with 240 FEMA claims averaging $7,933 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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. Flood damage can add significantly to the estimated <strong>$2,200</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
