Wyoming's Landfill Pollution Legacy

The state of Wyoming is not alone in the need to evaluate and potentially remediate old, unlined landfills. The American waste management sector has continually scored the highest grades in the American Society of Civil Engineers (ASCE) infrastructure “report cards.” This is largely due to the geosynthetic liners required in modern landfills. But old landfills, pre-code, are another matter. Wyoming estimates it may need $225 million over 20 years to address problems. A new facility in Casper is helping ease waste management needs.
