## Summary

The procurement process, awarded on 7th July 2025, involves the UK government department, the Environment Agency, contracting the UK Centre for Ecology & Hydrology (UKCEH) for a feasibility study focused on passive sampling biota replacement in freshwater environments. This initiative falls under the category of Research and Development Consultancy Services and is a call-off from a framework agreement, with the procurement method being selective. The project, titled "RDE811 - F6a. Passive sampling biota replacement feasibility study (freshwater)", is valued at £50,000 and spans from 10th July 2025 to 28th February 2026. The work areas include the United Kingdom, British Overseas Territories, Channel Islands, Europe, Isle of Man, and the rest of the world.

This contract presents significant growth opportunities for businesses involved in environmental consultancy and research, particularly those that specialise in hydrophobic persistent, bioaccumulative, and toxic (PBT) chemical monitoring. While the current supplier, UKCEH, secured the contract, similar organisations with expertise in ecology and hydrology can explore future opportunities in this domain. Businesses with a large operational scale may find it particularly advantageous to pursue similar tenders to expand their market presence and expertise in environmental monitoring solutions.

## Notice

This project is the first work package of a wider work to explore the opportunities for using PSDs to monitor hydrophobic PBT chemicals in the environment. Contract awarded by Defra.
