Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Evansdale's Housing Stock?
With 72% 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
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Evansdale's median build year of 1968 places it squarely in that category.
Over half of homes in Evansdale were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Evansdale: Remediation Cost in Perspective
Given current Evansdale property values, the remediation-to-equity ratio falls in the elevated tier — deliberate financial planning is a meaningful factor in how homeowners approach the documented water and safety issues on record here.
At 2.1% of home value, remediation costs in Evansdale represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $2,000–$4,100. Home values here are 13% below the Iowa average.
Protecting Children from Lead in Evansdale
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.
Routinely in Evansdale, where 72% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.

Climate-Related Water Risk for Evansdale
Measured across the NFIP's multi-decade tracking period, Evansdale shows a moderate flood record — 43 claims and 100% of ZIP codes carrying FEMA flood zone status. For water quality, that combination matters because flood events at this frequency can periodically stress infrastructure: treatment plants, private wells, and distribution systems all face elevated risk during significant flooding.
Evansdale has a moderate flood history with 43 FEMA claims averaging $6,201 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>$3,000</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.
