Housing Age Profile
The story of Denali National Park's housing stock is one of layered development - neighborhoods built in different decades, each carrying the plumbing standards of their era. The median build year of 1981 reflects that layered character. Before 1986, lead solder was standard in copper plumbing; before 1970, lead pipes were commonly used for service lines. A substantial portion of the pre-1986 homes visible in the distribution above still carry the plumbing materials of those earlier standards - creating a risk environment that the city-wide aggregate water data doesn't fully capture.
Most homes in Denali National Park were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Denali National Park
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 43% pre-rule share in Denali National Park keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
