Tim Deveaux is a retired independent environmental health practitioner with over 36 years of public sector experience in a wide range of areas in environmental health and sustainability. His experience includes housing, drainage, food safety, health and safety, air pollution and noise, infectious disease control, developing and implementing strategies to change behaviour and protecting the environment and human health, particularly in planning for, and implementing, climate change and sustainability solutions. Bill Bassett authored the first seven editions of Environmental Health Procedures, the first of which appeared in 1983. His dedication to navigating and clarifying the relevant regulations and laws in this book has aided countless environmental health practitioners in the UK and beyond.

Bill sadly died in 2017, and his legacy remains a testament to a leading, visionary and dedicated environmental health practitioner.
