Key Contaminants Detected in Barnsdall
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Barnsdall's Housing Stock?
With 65% 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. Barnsdall's median build year of 1975 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 Barnsdall were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Barnsdall: Remediation Cost in Perspective
Because estimated remediation claims a substantial fraction of typical Barnsdall property equity, the household financial perspective here requires serious advance planning — the cost-to-value ratio is in the elevated tier and warrants structured preparation.
At 2.1% of home value, remediation costs in Barnsdall represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,400–$4,100. Home values here are 23% below the Oklahoma average.
Protecting Children from Lead in Barnsdall
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 65% pre-rule share in Barnsdall keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

Climate-Related Water Risk for Barnsdall
The National Flood Insurance Program captures decades of claims at the local level, building a record of cumulative community flood exposure. For Barnsdall, that record documents 3 claims and 100% of ZIP codes inside FEMA-designated flood zones. What makes those numbers relevant to water quality is the set of mechanisms flooding activates: heavy precipitation that floods treatment intake zones can introduce contaminants upstream of normal filtration; well casings in low-lying areas can be infiltrated by floodwaters carrying bacteria, sediment, and chemical residue; and distribution system pressure changes during flooding can create backflow conditions. These effects become more probable as flood frequency and magnitude increase — and the NFIP record indicates both are meaningful factors locally.
Barnsdall has a moderate flood history with 3 FEMA claims averaging $1,683 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$2,300</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
