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.

Chemistry is part of the mix for contaminated land …

We frequently get looks of horror when we tell delegates that risk assessors, consultants and reviewers need to understand the chemistry of each contaminant of concern.  But this does not mean risk assessors, consultants and local authority regulators need degree-level chemistry, simply an outline understand of the chemical properties of each contaminant.

Armed with this information you can start to address important questions about the potential risks each contaminant may pose because these chemical properties dictate how it will behave in the environment.  Will it be mobile or will it bind to organic matter within the soil? Is is soluble and likely to leach towards the groundwater? Will it behave as a NAPL?  And if so will it form a floating layer on top of the groundwater (an LNAPL) or sink to the base of the aquifer (a DNAPL)?  Will it form a vapour that could impact nearby properties?  Is it likely to be bioaccumulatory and persistent? Without the answers to these types of questions a risk assessor cannot be sure that their conceptual site model includes all the relevant pathways and receptors for that contaminant, and so cannot guarantee that the resulting risk assessment is suitable, sufficient and robust.

LQM’s Introduction to Chemistry for Contaminated Land course is designed to assist delegates of any level to understand the likely behaviour of contaminants in the environment and help them to translate the names in a analytical certificate into concepts relating to potential risks.  But chemistry does not need to be boring and, although the day covers a lot of information, it is designed to be fun and interactive – most people particularly enjoy building models of their favorite organic contaminants so that they can put a “face” to the names.

Our next course will be running in Nottingham 27 June 2017, so if you think you or a colleague may benefit from a better understanding of contaminant chemistry, please check out the course content and book via our webiste http://www.lqm.co.uk/training/introchem/.

I feel like I got a lot out of today and will definitely help understanding lab certificates! The run-through the common chemical contaminants and lab analytical techniques were perhaps the most useful. The handouts will no doubt be used as a reference resource when back at the office. The introduction module served as a timely reminder / refresh of the basics.” (Consultant, May 2016)

Practical’s & handouts comprehensive” (Consultant, May 2016)

Very wide ranging in both organic & inorganic chemistry & how they relate to contaminated land” (Consultant, May 2016)

Good course – helped me process the basics whilst keeping it related to contaminated land aspects” (Consultant, May 2016)
