The procurement process led by the Environment Agency, headquartered at Seacole Building, 2 Marsham Street, London, focuses on conducting supplementary investigations into PFAS problem sites, titled "PFAS Problem Sites Supplementary Investigations". Classified under the CPV code 73110000 for research services, it involves delivering addendums to desk studies by WSP for the Barrow and Beck Row sites.

Businesses offering research services in environmental and sustainability sectors, particularly those with established infrastructures for addressing contamination issues and producing comprehensive reports, have opportunities for growth by engaging in similar projects with public agencies.
