Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Garvin's Housing Stock?
With 69% 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
Heavily weighted toward older construction, Garvin's housing stock carries a median build year of 1972. That profile puts a majority of homes in the era when lead-soldered copper plumbing was standard practice.
Over half of homes in Garvin were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Garvin: Remediation Cost in Perspective
Equity impact data for Garvin lands in the favorable tier — remediation claims a small slice of what properties here are worth.
Remediation costs in Garvin are relatively low compared to home values. The $300–$1,500 estimated range is a small fraction of median property value. Home values are 4% below the Oklahoma average.
Protecting Children from Lead in Garvin
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 69% of the Garvin 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.
