Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Stillwater Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
A citywide median of 1993 for construction says little about any single address in Stillwater. Homes built before 1986, when federal amendments restricted the lead content allowed in new pipe, solder and flux, may contain plumbing materials with more lead, and later renovations may have replaced them. An inspection of the plumbing can identify the materials, and sending a tap water sample to an accredited laboratory measures lead.
Most homes in Stillwater were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Stillwater: 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.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.

Stillwater: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Stillwater contains 87 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $14,226. Among ZIP codes with claim records, 67% 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 $850 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.
