Key Contaminants Detected in Black Canyon City
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Black Canyon City's Housing Stock?
With 47% 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
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In Black Canyon City, the median build year of 1982 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
Most homes in Black Canyon City were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Black Canyon City: Remediation Cost in Perspective
In Black Canyon City, the equity impact of remediation is proportionally small — not the kind of financial commitment that rises to the level of a genuine planning constraint, but a minor share of what most properties here are worth.
Remediation costs in Black Canyon City are relatively low compared to home values. The $1,500–$4,800 estimated range is a small fraction of median property value. Home values are 6% below the Arizona average.
Protecting Children from Lead in Black Canyon City
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 Black Canyon City, where 47% 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.

Climate-Related Water Risk for Black Canyon City
Within the NFIP's national dataset, Black Canyon City falls in moderate-exposure territory — 5 documented incidents spanning multiple decades, with 100% of local ZIP codes sitting inside FEMA flood boundaries. That combination warrants inclusion in any thorough local water quality review.

How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies.

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.
