        "description": "The overarching PFAS Risk Screening Project, now in its fourth phase, aims to assess and tackle the risks arising from a group of \"forever chemicals\" which are contaminating soil, groundwater and surface waters and pose a risk to human health. In order to ensure effective mitigation actions are appropriately targeted, we need to better understand the sources of PFAS, and the pathways by which these chemicals can impact key receptors. Previous phases of the project have led to the development of a high-level risk screening model. This layered GIS model helps to identify potential problem zones across England using a multi-criteria analytical approach to evaluate risk. The model allocates scores based on respective weightings applied to key criteria - all designed around the source-pathway-receptor type strategy. Based on the outputs of the model, and our growing understanding of the nature and extent of the PFAS problem, under Phase 4 we intend to focus in on specific facilities and zones of concern to both validate the model and target resource. Phase 4 will be divided into five Lots and suppliers are invited to bid for one, several or all of the Lots. A single contract will be awarded for each Lot and each Lot will be evaluated independently from each other. The Environment Agency has secured funding to deliver this work over the next three financial years. It is anticipated that some of the Lots will have a clear start and end date, whilst others will be dependent on findings, which may lead to additional tasks being required. We will therefore be requesting a fixed cost to deliver the Year 1 work defined in the Specification for each Lot and fixed rates which will be used to deliver subsequent work should it be required. It is anticipated that work under Phase 4 Contracts will begin at the end of August 2022. Each Lot has an estimated timeline for completion as indicated below. Lot 1 - 12 months Lot 2 - 12 months with option to extend into Years 2 and 3 depending on outputs and recommendations Lot 3 - 12 months with option to extend into Year 2 Lot 4 - 12 months with option to extend into Years 2 and 3 depending on outputs and recommendations Lot 5 - 12 months with option to extend into Year 2",

Providing background to the problem, the nature and characteristics of these chemicals, and the tailored approach necessary to best assess the risk, apply regulatory controls and ultimately implement mitigation measures (if necessary).

Aiming to deliver a comprehensive independent desk study report for each the highlighted sites providing background context, assessment of the evidence base, development of a robust conceptual site model, and recommendations for further, potentially more in-depth or site-based investigation. It is likely that any subsequent site evaluation will be conducted under Part 2A of the Environmental Protection Act 1990, and so the approach adopted for site evaluation should follow Part 2A procedures. In addition to desk-based site assessment activities mentioned above, we have already built-up sufficient evidence on a number of particular sites to justify on-site investigation works. Under Lot 2 we are seeking a specialist consultancy to deliver an intrusive site investigation on one of these highlighted sites, to further refine the conceptual site model and deliver conclusions under the Part 2A regulatory regime. Whilst PFAS are the primary contaminants of concern, in accordance with Part 2A, all potential contaminant linkages should be thoroughly evaluated.

                "description": "Lot 4: Phase 3 included an extensive monitoring exercise for water and leachate from a wide variety of landfill facilities. This ran in parallel with a DEFRA initiated landfill study. The aim was to assess PFAS and wider POPs generation and potential release into the environment. Lot 4 aims to build on this work and focus in on specific emissions from landfills to ascertain key release mechanisms for this family of chemicals. The sub tasks under Lot 4 include: * Assessment of pre and post treated leachate to evaluate PFAS component o Some studies have shown that on-site treatment can have little or no effect on PFAS substances within leachate. These leachates are then discharged to either sewage or wastewater treatment works either by direct sewer connection or tanker transfer. This study aims to assess pre and post treatment concentrations and what levels are making their way to treatment works. It will involve sampling from key locations at a pre-selected number of landfill facilities and the receiving water treatment works. * Assessment of sludges produced and POPs component o Whilst PFAS can remain largely untreated by on-site treatment facilities, many POPs are removed and most likely end up in the resulting sludges. The relative proportion is unknown. And the risk from this contaminant loading to environmental media from disposal of these sludges is also unknown. This study aims to provide additional detail by sampling the sludges from a number of landfill treatment plants and at either the point of disposal or at other intermediate treatment facilities to quantify the mass of particular POPs being released to the environment (e.g. via land spreading) and/or being destroyed at other treatment facilities. * Assessment of POPs release into GW from older unlined facilities o This task aims to assess whether PFAS and/or other POPs are being released to the environment via contaminant migration from unlined older (dilute and disperse) landfills into the underlying and surrounding groundwaters (and/or surface waters). The task would involve sampling of the raw leachate and groundwater both up and down hydraulic gradient of the landfill site. * Study of PFAS in gaseous emissions o This sub task aims to qualify / quantify the potential release of PFAS in trace gases released at landfills from the combustion gas treatment systems (landfill engines and flares) and gasses passively venting from the landfill itself. The task will involve sampling from various key locations likely to include: Raw gas at the well head or manifold; sampling the gas condensate within the gas collection pipework; sampling the soils downwind of the combustion treatment plant and beyond the landfill site boundary; and, sampling of the waste oils and slippage combustion products from the gas engine.

In order to assess the scale of the problem, to develop a countrywide picture, and to help evaluate risk, a comprehensive study of background concentrations is considered necessary. This would be conducted in collaboration with the British Geological Society (BGS) as a sub-contractor to the main Contractor, who would help facilitate mapping, provide geological context and potentially access to archived soil samples. It is currently anticipated that this task would include widespread soil sampling from a representative range of environments.
