What's in Concho's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Concho Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
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 Concho, the median build year of 1996 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
Most homes in Concho were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Concho
While no remediation project is entirely without cost, the relationship between estimated remediation and property values in Concho is notably favorable — the equity share is small enough that the household financial perspective is one of proportionality rather than pressure, and most homeowners can treat it as routine planning rather than a significant financial event.
Remediation costs in Concho are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 66% below the Arizona average.
Concho: 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.
Older stock in Concho represents 34% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.
