Key Contaminants Detected in Lynnwood
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Lynnwood's Housing Stock?
With 46% 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
What does a median build year of 1994 mean for water safety in Lynnwood? It means the housing stock straddles two key plumbing thresholds: the 1986 federal ban on lead solder in copper plumbing, and the pre-1970 era when lead pipes were commonly installed for service lines. A meaningful share of homes predates one or both of those cutoffs, creating varied risk levels across the city's housing inventory.
Most homes in Lynnwood were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.
Source: U.S. Census Bureau ACS B25034.
Lynnwood: Remediation Cost in Perspective
How much of a Lynnwood 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 Lynnwood are relatively low compared to home values. The $933–$2,033 estimated range is a small fraction of median property value. Home values are 46% above the Washington average.
Protecting Children from Lead in Lynnwood
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.
Reading the local data together points toward a structural gap that matters more here than in low-exposure communities. 46% of Lynnwood stock comes from the pre-rule era, and citywide monitoring either approaches or sits beyond the federal benchmark under Lead and Copper Rule sampling. A baseline kit fits the routine-diligence category, with certified filtration available via retailer networks where confirmed faucet results warrant additional measures.

Historical Flood-Claim Evidence for Lynnwood
Historical NFIP data for Lynnwood contains 52 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $39,740. Among ZIP codes with claim records, 0% 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>$1,400</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.
