How Old Is Adak's Housing Stock?
With 70% 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
Because the majority of Adak's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1988 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Adak were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Adak: Remediation Cost in Perspective
While no remediation project is entirely without cost, the relationship between estimated remediation and property values in Adak is notably favorable - the equity share is small enough that the household financial perspective is one of proportionality rather than pressure, and most homeowners can treat it as routine planning rather than a significant financial event.
Remediation costs in Adak are relatively low compared to home values. The $300–$1,500 estimated range is a small fraction of median property value. Home values are 61% below the Alaska average.
Protecting Children from Lead in Adak
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 70% of the Adak 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.
