Key Contaminants Detected in Viola
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Viola's Housing Stock?
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
Prohibited from residential plumbing since 1986, lead solder divides Viola's housing stock along a timeline that the median build year of 1994 straddles. A meaningful share of homes predates the ban - a configuration that places moderate aggregate pressure on plumbing-related lead risk, distributed unevenly across neighborhoods.
Most homes in Viola were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Viola: Remediation Cost in Perspective
Low proportionality - that's the Viola picture when remediation costs are placed against typical home equity.
Remediation costs in Viola are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 44% above the Idaho average.
Protecting Children from Lead in Viola
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 38% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Viola.
