PFAS

Reducing per/poly fluoroalkyl substance (PFAS) discharges is becoming a priority for Wisconsin wastewater treatment facilities (WWTFs). Finding the source(s) of PFAS is the first step.

Leachate from most landfills, especially municipal solid waste (MSW) sites, contain significant amounts of PFAS. Actions taken by WWTFs to reduce PFAS concentrations in their effluent may range from limiting the number of loads accepted per week to completely banning leachate from the facility.

A proven approach for removal of PFAS is with a carbon filter.  Carbon filtration is particularly effective for PFOS and PFOA and other PFAS with six or more carbons.

Carbon filtration can effectively treat most landfill leachate to below surface water standards for PFOS and PFOA.  In addition, the majority of other PFAS as well as heavy metals and volatile organic chemicals (VOCs) will likewise be greatly reduced.

Sand County Environmental specializes in operations, maintenance, and monitoring (OMM) of closed landfills.  Since 2000, we have been working with carbon filtration of leachate.  We have the expertise and hands on experience needed to design, permit, and install cost effective leachate filtration systems.
