LQM is a specialist environmental consultancy based in Nottingham (UK) with an international reputation for assessing and managing the risks posed to human health and the environment by contaminants in soil. Increasingly this is being done within a context of sustainable development and specifically sustainable brownfield regeneration.

We provide consultancy, peer review and expert witness services, contract research and training courses on all aspects of the management of land contamination to problem holders, developers and local government.

Webinar Recording: Innovations in ground gas and vapour sampling and analysis, groundwater sampling and analysis

Only £60 (excl VAT) with online card payment discount.

Our ability to measure hazardous ground gases and vapours or detect low levels of dissolved phase contaminants in ground water rather than relying on conservative and poorly constrained modelling has improved in recent years. New technologies are enabling real time data to be collected. New analytical techniques are providing greater insights in the composition and potential origins of hazardous gas, vapour or dissolved phase contaminants.

This webinar will explore the role innovative sampling and analytical techniques have in better managing land contamination on post industrial brownfield sites or, the rare, Part 2A sites.

This ~120min recording of the Professional Practice Webinar was originally delivered on 13th February 2019 (NOTE: only access to the recording will be provided, original handouts are not included). The webinar was delivered by Paul Nathanail as part of LQM's continued commitment to raising standards among practitioners and regulators on topics of timely relevance.

Prices and discounts: Prices exclude VAT. Please note purchase is via online card payment only - a 20% discount will automatically be applied.

Invoice purchases will be declined

Recording link: provided by email once payment has been received.

  • Content
  • Citation

This webinar covered:

  • examples of recent innovations in sampling and analyse
  • understanding of their capabilities and limitations
  • understanding of how these techniques can improve your risk assessments
  • outline sources of the relevant guidance and sources of information

By the end of the webinar, you will:

  • Understand the limitations of conventional methods of sampling and analysing ground gas, vapour and water
  • Understand how more representative sampling can improve risk assessments and minimise unnecessary remediation
  • Understand how the outcomes can be used in risk assessments that move us beyond over simplistic concentration or detection based triggers for remediation
  • Be familiar with sources of further guidance on the sampling and analysis of ground gas, vapour and water
