Housing Age Profile
Pre-1986 plumbing is not a rare legacy case in Big Piney — it's the dominant profile. The median build year of 1985 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Big Piney were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Big Piney Homeowners
Given current Big Piney valuations, the remediation-to-property-value ratio is low — most homeowners are looking at a proportionally modest share that fits within routine financial planning.
Remediation costs in Big Piney are relatively low compared to home values. The $950–$2,100 estimated range is a small fraction of median property value. Home values are 26% below the Wyoming average.
Lead Exposure Risk for Children in Big Piney
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.
Older interior plumbing shapes the local picture: 53% of Big Piney homes predate the federal solder ban, and aggregate sampling either approaches or crosses the action benchmark. That mix makes a single-home draw a standard pre-purchase or pre-occupancy step.
