Housing Age Profile
Tap water lead levels are shaped by two factors: what the utility delivers, and what the household plumbing adds to it. Older homes contribute disproportionately to that second variable because lead solder was standard in copper plumbing before 1986, and lead pipes were common before 1970. In Hakalau, where the median build year is 1994, a substantial share of the housing stock falls into these older categories. The bar chart above breaks out the pre-1970, 1970-to-1986, and post-1986 segments - the key ages for understanding where plumbing-era risk concentrates across the city.
Most homes in Hakalau were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Hakalau: Lead Risk & Vulnerable Populations
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 41% of the Hakalau inventory was built in that earlier era - a share large enough to move household-level reads onto the standard list.
