Key Contaminants Detected in Wellton
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Wellton'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
Why does housing age matter for water safety? Homes built before 1986 may have lead-soldered copper plumbing joints — a practice banned that year. Wellton's median build year of 1991 places much of the city's housing in the post-ban era, reducing that specific risk pathway for most residents.
Most homes in Wellton were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Wellton: Remediation Cost in Perspective
Homeowners in Wellton are working with a moderate equity share for documented remediation — the commitment deserves a line in the household budget, not dismissal.
Remediation costs are moderate relative to home values in Wellton. The estimated $1,100–$4,100 range is manageable for most homeowners but still worth budgeting for. Home values are 62% below the Arizona average.
Protecting Children from Lead in Wellton
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.
Generally, the structural picture for Wellton runs in a quiet direction. Aggregate sampling rests under the federal action benchmark, and 25% of housing comes from the pre-rule era — a contained local footprint. That dual signal keeps lead in the background of local concerns, while a one-faucet measurement still answers a different question than any system average can: what is actually flowing from one specific tap on a given morning.

Climate-Related Water Risk for Wellton
FEMA data shows 100% of Wellton's ZIP codes mapped into designated flood zones, paired with an NFIP record of 19 claims. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Wellton has a moderate flood history with 19 FEMA claims averaging $17,354 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.
