How Old Is Lyman's Housing Stock?
With 66% 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.

Housing Age Profile
Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Lyman's median build year of 1959 reflects a housing stock where these older materials are a pervasive feature — not a rare legacy — of the residential plumbing landscape.
Over half of homes in Lyman were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Lyman: Remediation Cost in Perspective
Across Lyman, the equity share taken up by estimated remediation is small — a favorable ratio for most property owners.
Remediation costs in Lyman are relatively low compared to home values. The $800–$1,800 estimated range is a small fraction of median property value. Home values are 17% below the Washington average.
Protecting Children from Lead in Lyman
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 66% pre-rule share in Lyman keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

Climate-Related Water Risk for Lyman
Within the NFIP's national dataset, Lyman falls in moderate-exposure territory — 4 documented incidents spanning multiple decades, with 100% of local ZIP codes sitting inside FEMA flood boundaries. That combination warrants inclusion in any thorough local water quality review.
Lyman has a moderate flood history with 4 FEMA claims averaging $923 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>$1,200</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.
