Housing & Infrastructure in Grand Portage
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In Grand Portage, the median build year of 1997 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
Most homes in Grand Portage were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Grand Portage Homeowners
Because property values in Grand Portage comfortably exceed estimated remediation costs, the equity impact here is proportionally small.

Lead Exposure Risk for Children in Grand Portage
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 39% pre-rule share in Grand Portage keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
