Key Contaminants Detected in Foss
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Foss's Housing Stock?
With 70% 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
Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Foss's median build year of 1976 reflects a housing stock where these older materials are a pervasive feature — not a rare legacy — of the residential plumbing landscape.
Over half of homes in Foss were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Foss: Remediation Cost in Perspective
Given that Foss falls in the elevated cost-to-value tier, the equity impact of documented remediation is a real financial planning challenge for most homeowners.
At 2.6% of home value, remediation costs in Foss represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $2,950–$6,200. Home values here are 20% above the Oklahoma average.
Protecting Children from Lead in Foss
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.
Jointly, the 70% older-stock share in Foss alongside aggregate readings past the regulatory action threshold raises lead to a near-term homeowner attention point — sharper for families with young children.
<strong>1 ZIP code</strong> (100% of the city) exceeds the EPA lead action level of 0.015 mg/L.
