## Summary

The Department for Environment, Food & Rural Affairs (DEFRA) has issued a tender titled "Review of Radon and Tritium in Drinking Water in the UK" in the services category. The project involves updating hazard maps for radon and tritium levels in drinking water in the UK to inform regulatory positions. The tender deadline for submissions is 29th March 2023, with a contract period starting from 8th May 2023 to 8th February 2024.

This tender presents an opportunity for businesses providing research and experimental development services, specifically in the area of drinking water. Small and medium-sized enterprises (SMEs) and voluntary, community, and social enterprise (VCSE) organisations are encouraged to participate. By engaging in this tender, businesses can contribute to updating regulatory standards for radon and tritium in public water supplies, thus influencing water safety guidelines in the UK.

## Notice

The aim of this research project is to update the existing hazard maps, that were originally published in 2015, for the probability of exceeding specific radon levels in water. In addition, the project aims to collate and review existing knowledge, research and data on the areas of risk of tritium in England and Wales and develop a hazard map for the risk of exceeding specific tritium levels in water. The findings of this research project will be used to inform our regulatory position in relation to radon and tritium in public supplies and used to update our private water supplies guidance on radon and tritium. This project will provide an opportunity to update the evidence base from which to evaluate the regulatory standards in relation to radon and tritium.
