PFAS Risk Screening Project Phase 4, Work Package 5 - Landfill Emissions Assessment

• Value: £555K

This task focuses on sampling, analysis and assessment of raw and treated non-hazardous landfill leachates, gas condensates and biosolids (sludges) from a variety of on-site landfill leachate treatment plants (LTP).

• Value: £240K

This task aims to assess the proportional loading of PFAS and POPs from raw and treated non-hazardous landfill leachates against those reported at wastewater/sewage treatment works.

• Value: £460K

This task aims to gather additional non-hazardous landfill leachate and groundwater/ surface water samples and evaluate PFAS and POPs emissions to the environment via contaminant migration from unlined and lined landfills to the underlying and surrounding groundwaters and/or surface waters.

• Value: £450K

This task aims to: • identify PFAS and qualify and quantify the potential release from non-hazardous landfills involving the sampling from key gas emission locations around targeted landfills, including where possible: o gas condensates o raw gas (wellheads) from the gas field o raw gas inlet to either landfill gas engine and/or flare o combustion gas treatment systems (landfill engines and flares stacks) • sample and analyses landfill trace gases as described in Appendices 2 and 3 in the EA report, The Quantification of trace components in landfill gas (P1-491 TR) to update our existing records.
