Welcome to the September 2026 edition of AGS Magazine. As the summer draws to a close and we look ahead to the final quarter of the year, our industry continues to demonstrate its ability to adapt, collaborate and respond to the evolving challenges facing the built environment.

Across the geotechnical and geoenvironmental sectors, the importance of robust guidance, shared learning and practical innovation remains clear. Whether addressing emerging contaminants, improving investigation and monitoring practices, supporting safer working environments, or helping clients understand good practice, the work of the AGS continues to play a vital role in raising standards across the industry.

This issue brings together a wide range of insight, guidance and updates that reflect the breadth of our sector. Articles explore topics including pesticide use on agricultural land and human health risk assessment, horizontal directional drilling, good gas monitoring, SPT reporting, health and safety, sustainability, standards, and the role of storytelling in inspiring the future of ground engineering. We also highlight recent and upcoming AGS events, webinar replays, and opportunities for early careers professionals to get involved, including the latest AGS Early Careers Poster Competition.

As ever, I encourage you to take the time to read the articles, share them with colleagues, and consider how the guidance and ideas presented here may support your own work. Your contributions, whether through technical articles, event participation, committee involvement or feedback, are central to the strength and relevance of the AGS.
