Housing & Infrastructure in Dewar
With 63% 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, Dewar's housing stock carries a median build year of 1975. That profile puts a majority of homes in the era when lead-soldered copper plumbing was standard practice.
Over half of homes in Dewar were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Dewar Homeowners
In Dewar, the remediation-to-property-value ratio is elevated enough that homeowners who identify documented issues early have an advantage - understanding the scope, sequencing by urgency, and phasing the work against household budget capacity are the practical levers that determine whether remediation feels manageable or overwhelming at this equity tier.
At 2.1% of home value, remediation costs in Dewar represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,100–$3,300. Home values here are 41% below the Oklahoma average.
Lead Exposure Risk for Children in Dewar
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.
When older housing represents 63% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Dewar address.

Historical NFIP Claim Context in Dewar
Historical NFIP data for Dewar contains 6 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $19,729. 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>$1,800</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.
