Because the median home value in Calumet is large relative to the estimated cost of remediation, the ratio between them stays at or below 1%; that is a statement about two area-level numbers, not a quote for a particular house or a judgment about what an owner can pay.
Estimated remediation costs in Calumet can be compared with local home values. The $150–$600 estimated range can be set against the median property value; actual costs vary by home. Home values are 55% below the Michigan average.
Lead Exposure Risk for Children in Calumet
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.
