Housing & Infrastructure in Noble
With 44% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Over the decades, Noble accumulated housing from multiple construction periods. The median build year of 1982 can be read against 1986, when lead solder in plumbing became federally prohibited - a regulatory line, not a safety line, and individual homes on either side of it can have different plumbing.
Most homes in Noble were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Noble Homeowners
Relative to home values, Noble remediation estimates run low.
Estimated remediation costs in Noble can be compared with local home values. The $600–$2,300 estimated range can be set against the median property value; actual costs vary by home. Home values are 30% above the Oklahoma average.
Lead Exposure Risk for Children in Noble
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.

Historical NFIP Claim Context in Noble
Historical NFIP data for Noble contains 4 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $4,438. 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 $1,100 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.
