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.

mg/L Avg Lead (Limit: 0.015)

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.
