Key Contaminants Detected in Dewey
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Dewey's Housing Stock?
With 73% 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
For residents trying to assess tap water risk in Dewey, the median build year of 1950 is the starting context. It signals that a majority of homes were constructed before 1986 - the year federal rules prohibited lead solder in new plumbing - and that a significant share likely predates 1970, when lead pipes were still a common choice for residential service connections. Neither risk tier is rare in this housing inventory.
Over half of homes in Dewey were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Dewey: Remediation Cost in Perspective
The equity share of documented remediation in Dewey is high - a cost-to-value ratio that places this market in the elevated tier and means most homeowners are weighing a financial decision where scoping by urgency, mapping costs against household budget, and knowing what assistance options exist are practical steps that can materially improve outcomes.
At 2.1% of home value, remediation costs in Dewey represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,800–$4,800. Home values here are 4% below the Oklahoma average.
Protecting Children from Lead in Dewey
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 73% of the Dewey inventory was built in that earlier era - a share large enough to move household-level reads onto the standard list.

Historical Flood-Claim Evidence for Dewey
Historical NFIP data for Dewey contains 33 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $27,439. Among ZIP codes with claim records, 100% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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. The <strong>$2,900</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
