Washington Infrastructure Age
With 68% 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. Washington's median build year of 1964 places it squarely in that category.
Over half of homes in Washington were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Washington
At current Washington valuations, the remediation share sits in the elevated tier — a level where deliberate financial planning becomes a practical prerequisite rather than a convenience for most homeowners.
At 2.1% of home value, remediation costs in Washington represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,950–$5,400. Home values here are 13% below the Indiana average.
Washington: 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 Washington represents 68% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.

Washington: Flood History & Water Damage Risk
Measured across the NFIP's multi-decade tracking period, Washington shows a moderate flood record — 2 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.
Washington has a moderate flood history with 2 FEMA claims averaging $62,264 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>$3,200</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.

What You Can Do in Washington
- Test your water at home. City-level data shows averages — your tap may differ. Lead testing is especially recommended given the area's lead levels.
- Install a certified water filter. Filters rated for Surface Water Treatment Rule can reduce the most common contaminant found in Washington's water.
- Check your home's plumbing. With 68% of homes built before 1986, lead solder is a real possibility.
