Oakdale Infrastructure Age
With 50% 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
Renovation history matters as much as age: in Oakdale, with a median build year of 1984, some older homes have been replumbed and some have not.
Over half of homes in Oakdale were built before 1986, when federal law began restricting lead solder in drinking-water plumbing. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Oakdale: Lead Risk & Vulnerable Populations
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.
Two pieces of area data frame lead for Oakdale families. First, the average of ZIP-level 90th-percentile lead results is 0.010 mg/L or higher. Second, census figures put homes built before 1986, which are more likely to contain lead pipes, fixtures or solder, at about 50% of the housing stock. Neither figure measures a particular home, so a certified lab test of the tap water is the step that shows the lead level there.

Oakdale: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Oakdale contains 2 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $4,879. Among ZIP codes with claim records, 0% 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 $300 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.
