Housing Age Profile
Heavily weighted toward older construction, Seal Rock's housing stock carries a median build year of 1985. That profile puts a majority of homes in the era when lead-soldered copper plumbing was standard practice.
Over half of homes in Seal Rock were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Seal Rock Homeowners
The household financial picture for Seal Rock homeowners is proportionally favorable — addressing documented issues claims a small slice of equity, and the cost-to-value ratio puts this area well within the manageable tier.
Remediation costs in Seal Rock are relatively low compared to home values. The $1,200–$2,500 estimated range is a small fraction of median property value. Home values are 2% above the Oregon average.
Lead Exposure Risk for Children in Seal Rock
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.
After the federal action removing lead-bearing solder from new plumbing took effect, building practice shifted — but 52% of the Seal Rock inventory predates that line. With aggregate samples near or beyond 0.015 mg/L, an in-home check moves out of the optional column into the standard list.

How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies.

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.
