Key Contaminants Detected in Selawik
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Selawik's Housing Stock?
With 44% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
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 Selawik, where the median build year is 1982, 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 Selawik were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Selawik: Remediation Cost in Perspective
Within the Selawik market, documented remediation claims a significant slice of typical equity — the financial weight here is material.
At 2.5% of home value, remediation costs in Selawik represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,100–$3,300. Home values here are 63% below the Alaska average.
Protecting Children from Lead in Selawik
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 44% of the Selawik inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.

Climate-Related Water Risk for Selawik
Multiple flood events have been recorded for Selawik through the NFIP — 3 claims in total, with 100% of ZIP codes in FEMA-designated zones — pointing to a flood exposure profile that merits inclusion in a water quality assessment without reaching high-severity planning territory.
Selawik has a moderate flood history with 3 FEMA claims averaging $2,566 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>$1,800</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.
