08:25 AM EDT, 07/23/2024 (MT Newswires) -- Waste Connections ( WCN ) on Tuesday said it will use Montrose Environmental Group's per- and polyfluoroalkyl substances (PFAS) treatment system to address impacted landfill leachate at Waste Connections' ( WCN ) Champ Landfill in Missouri.

Landfill leachate forms when rainwater passes through wastes in a landfill. Unlike municipal water, it increases treatment challenges as it varies in composition and contains dissolved and suspended materials.

Montrose subsidiary ECT2's Foam-X treatment system is effective at treating PFAS in liquid waste with high levels of co-contaminants, including landfill leachate, according to a statement.

"Air is injected in the form of tiny bubbles, which attracts PFAS to the air-water interface, removing it from the water column. Removing PFAS from landfill leachate breaks the cycle of PFAS from discarded consumer products entering our waterways and dispersing through the environment," said Vijay Manthripragada, President and Chief Executive Officer of Montrose Environmental Group.

In January 2023, the Environmental Protection Agency released Effluent Guidelines Program Plan 15 which announced plans to develop new effluent limitation guidelines and pretreatment standards to reduce the presence of PFAS in landfill leachate.
