PFAS Treatment
Per- and polyfluoroalkyl substances (PFAS), commonly known as "forever chemicals," are a group of synthetic chemicals widely used in consumer and industrial products. Solid waste landfills, which act as passive receivers of PFAS-containing wastes, are designed to capture all liquids from the waste stream as well as infiltration of rain and snow, aggregating the leachate within containment areas. The leachate is then treated either on-site or off-site at a wastewater facility.
With an eye toward potential regulation of PFAS substances, we invested approximately $1 million per year over a five-year period toward research on innovative leachate treatment solutions. Additionally, we have partnered with several environmental firms to deploy foam fractionation technology at a number of our landfills to capture these substances and remove them from the environment. In aggregate, we possess capacity to process and remove PFAS from over over 90 million gallons of leachate across three new facilities, with additional systems planned for several landfills.
Improving PFAS Treatment
SKB Environmental, a Waste Connections subsidiary, installed the first nonpilot PFAS treatment plant for landfill leachates in the United States, reducing the risks associated with containing and transporting "forever chemicals." Read more here.
