Geomembrane Selection and Use in Evaporation Ponds

Part 1:  Evaporation Pond Operation and Containment Requirements

Since posting our first blog addressing the recent interest in exposed Geomembrane covers, discussion around the topic has continued throughout the industry. More specifically, the conversation often revolves around the same question: How can certain geomembranes be made to work for exposed applications? 

In October 2022, the U.S. Environmental Protection Agency (EPA) announced $2 million in research grant funding as part of their Lagoon Wastewater Treatment Plan. The grants are one component of the EPA’s Lagoon Wastewater Treatment Action Plan, a broad initiative to assist small, rural, and tribal communities with the utilization of lagoon wastewater systems.
