Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Nondalton Infrastructure Age
With 50% 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
Because the majority of Nondalton's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1984 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Nondalton 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 Nondalton
Because property values in Nondalton comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Nondalton are relatively low compared to home values. The $300–$1,500 estimated range is a small fraction of median property value. Home values are 30% below the Alaska average.
Nondalton: 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.
Routinely in Nondalton, where 50% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.
