With 2017 being the ‘Year of Risk’, the Contaminated Land Group proudly hosted this year’s Janet Watson meeting.

The conference explored emerging science, technologies and guidance in the contaminated land industry, told from the viewpoint of all the key stakeholders: the site owner, consultant, contractor and regulator.

Keynote talks were provided by accomplished industry leaders and the conference also provided a platform for scientific developments and innovative projects presented by the students, academics and early-career professionals working on them.

The varied programme included workshops, an expert panel discussion and presentations by speakers from a number of backgrounds. Whilst offering all delegates the opportunity to become up to date with many of the latest technologies and guidance, the conference also provided a great opportunity for networking particularly beneficial for early-career professionals interested in or are currently working towards chartership in contaminated land.
