What's in Kaltag's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Kaltag Infrastructure Age
With 55% 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
What does a median build year of 1985 mean for water safety in Kaltag? It means the majority of the city's residential plumbing was installed before 1986, when lead solder was federally banned, and a large share may predate 1970, when lead pipes were commonly used — making plumbing age a central variable in household-level lead risk across much of the city.
Over half of homes in Kaltag were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Kaltag
Placing remediation in the context of Kaltag's property market, the equity share is low — most homeowners here are weighing a financial commitment that fits comfortably within routine property planning, far from the threshold where remediation becomes a material equity decision rather than a standard upkeep consideration.
Remediation costs in Kaltag are relatively low compared to home values. The $300–$1,500 estimated range is a small fraction of median property value. Home values are 53% below the Alaska average.
Kaltag: 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 55% of the Kaltag inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.
