Key Contaminants Detected in Big Lake
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Big Lake's Housing Stock?
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
Median build year in Big Lake: 1993; a tap test shows what your own water delivers.
Most homes in Big Lake were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Big Lake: Remediation Cost in Perspective
The remediation-to-value ratio for Big Lake sits at the bottom of the scale.
Estimated remediation costs in Big Lake can be compared with local home values. The $300–$800 estimated range can be set against the median property value; actual costs vary by home. Home values are 40% above the Minnesota average.
Protecting Children from Lead in Big Lake
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.
For families with young children in Big Lake, two area figures are available: pre-1986 construction at about 27%, and a mean of the ZIP codes' 90th-percentile lead results under 0.010 mg/L. Testing water from the tap a child drinks from gives a home-specific result.

Historical Flood-Claim Evidence for Big Lake
Historical NFIP data for Big Lake contains 2 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $2,049. 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 $500 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.
