The procurement falls under the service category of research consultancy services. It involves conducting a Rapid Evidence Assessment to develop guidance on how to undertake detailed quantitative risk assessments for PFAS contaminated groundwater. The value of the contract is set at £60,000, with a submission deadline for quotations on 3rd October 2025. The contract period is slated to begin on 20th October 2025 and conclude on 31st March 2026. The procurement method is open competition, which is below the threshold, and requires quotations to be submitted in response to a Request for Quotation (RFQ). This tender presents considerable opportunities for businesses specialising in environmental research consultancy, particularly those with expertise in chemical assessments and risk modelling. Small and medium enterprises (SMEs) and voluntary, community, and social enterprises (VCSEs) may find this project particularly attractive, given the emphasis on research and data analysis for emergent environmental contaminants. Companies experienced in dealing with synthetically fluorinated chemicals, such as PFAS, and possessing the capability to provide robust, physio-chemical data assessments and modelling software inputs will be well-positioned to thrive in this project, potentially aiding in significant business growth within the environmental consultancy industry. ## Notice This project will commission a Rapid Evidence Assessment (REA) of published literature to identify evidence-backed robust physio-chemical data sources for 20 per- and poly-fluoroalkyl substances (PFAS) that could be used as inputs into a groundwater detailed quantitative risk assessment (DQRA) modelling software (e.g. ConSim and RTM). PFAS are a broad group of synthetic fluorinated chemicals which are persistent in the environment. Some are bio-accumulative and toxic, and/or highly mobile. PFAS are used in a wide variety of consumer products and industrial applications because of their unique chemical and physical properties, including oil, water and stain repellence, temperature and chemical resistance, and surfactant properties. Due to their widespread historical and current use, PFAS are prevalent within the water environment because of the direct and indirect pathways into groundwater and surface water from various applications and activities. The need for a consistent approach to assessing the risk of PFAS compounds to groundwater receptors is growing substantially due to increasing year on year attention to PFAS as an emerging contaminant, from the public, media, regulators, and industry. It is becoming more vital that we, as regulators, and industry, are able to understand the risks associated with PFAS, and can provide robust and consistent regulation in this emerging field. Alongside the REA, there is a requirement to produce a summary table of the required physio-chemical parameters, the data sources, and the justification for the inclusion of the data for the 20 PFAS. This REA and data summary table will be used to develop guidance on how to undertake a DQRA for PFAS contaminated groundwater. ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/060554-2025 | | Notice type | UK4 - Tender Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Open | | Procurement method details | Below threshold - open competition | | Tender suitability | SME, VCSE | | Awardee scale | Not specified | | All stages | Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 29 Sep 2025 | | Submission deadline | 3 Oct 2025 | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 19 Oct 2025 - 31 Mar 2026 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £50,000 | | Lots value | £50,000 | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Active | | Lots status | Active | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | ENVIRONMENT AGENCY | | Locality | LONDON | | Post town | South West London | | Postcode | SW1P 4DF | | Country | England | | ITL 1 | TLI London | | ITL 2 | TLI3 Inner London - West | | ITL 3 | TLI35 Westminster and City of London | | Local authority | Westminster | | Electoral ward | St James's | | Westminster constituency | Cities of London and Westminster | | Delivery location | Not specified | ## CPV Codes ### Divisions - 73 - Research and development services and related consultancy services ### Codes - 73210000 - Research consultancy services ## Release History - 29 Sep 2025 at 13:56 - TenderUpdate - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/060554-2025 - 16 Sep 2025 at 08:27 - Tender - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/056791-2025 ## Documents - https://www.find-tender.service.gov.uk/Notice/060554-2025 29th September 2025 - Tender notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/056791-2025 16th September 2025 - Tender notice on Find a Tender - https://www.find-tender.service.gov.uk/Notice/Attachment/A-5250 - https://www.find-tender.service.gov.uk/Notice/Attachment/A-5251 - https://www.find-tender.service.gov.uk/Notice/Attachment/A-5656 - https://www.find-tender.service.gov.uk/Notice/Attachment/A-5657 ## Notice URLs - https://www.legislation.gov.uk/ukpga/2023/54/contents ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
