Key Contaminants Detected in Yamhill
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Yamhill's Housing Stock?
With 41% 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
Plumbing risk in residential housing tracks directly to construction era: pre-1986 homes may have lead-soldered copper joints; pre-1970 homes may have lead pipes outright. Yamhill's median build year of 1999 places the city in a moderate risk zone where neither era dominates the housing inventory. Understanding which side of the 1986 threshold a specific property falls on - and whether it predates 1970 - is the most actionable starting point for a homeowner trying to assess their own tap water exposure.
Most homes in Yamhill were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Yamhill: Remediation Cost in Perspective
In Yamhill, 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 Yamhill are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 31% above the Oregon average.
Protecting Children from Lead in Yamhill
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.
After the federal action removing lead-bearing solder from new plumbing took effect, building practice shifted - but 41% of the Yamhill inventory predates that line. With aggregate samples near or beyond 0.015 mg/L, an in-home check moves out of the optional column into the standard list.
