Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Washington Infrastructure Age
With 42% 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
Two regulatory milestones define plumbing-era risk in residential housing: 1970, when lead pipes were still commonly installed for service lines, and 1986, when lead solder was banned from new copper plumbing. A median build year of 1980 places Washington in the middle zone between those thresholds - with a meaningful share of housing predating both cutoffs. The distribution shown above breaks out those eras explicitly, clarifying where concentrated risk sits across the residential inventory.
Most homes in Washington were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Washington
How much of a Washington home's value does documented remediation represent? A small fraction - the equity share here is in the low tier, and from a household financial perspective, most property owners are considering a commitment that fits comfortably within standard planning rather than a decision that rises to the level of a material budget event or significant equity consideration.
Remediation costs in Washington are relatively low compared to home values. The $1,250–$3,200 estimated range is a small fraction of median property value. Home values are 93% above the Oklahoma 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.
Throughout the multi-year monitoring window under Lead and Copper Rule sampling, citywide samples for Washington have moved past the regulatory action mark, and 42% of local stock comes from the pre-rule era. Both the housing inventory and the system data support active household-level reads as a practical step.
<strong>1 ZIP code</strong> (100% of the city) exceeds the EPA lead action level of 0.015 mg/L.

Washington: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Washington contains 5 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $13,383. Among ZIP codes with claim records, 100% 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>$2,000</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.
