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.

  1. Why does a contaminated land practitioner need to know about contaminant chemistry?

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

    Armed with this information a risk assessor or regulator 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 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.

    We will next be running this course in Nottingham in February and again in June, 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/.

  2. LQM/ Brownfieldbriefing Executive Briefing Webinars 2017

    They’re back! After the very succesful 5 webinar series in 2016 the brand new set of webinar topics kicks off with ‘Using open source GIS’. It seemed only right and proper to make registration for this webinar free. Details and registration at www.brownfieldbriefing.com/executive_briefings2017

  3. NEW LQM Course: GIS for Contaminated Land

    LQM are pleased to announce our new one-day GIS for Contaminated Land course using free open source GIS software that is readily available which can help you and your clients get better value from expensive SI data.

    For further information see our short GIS promo video or http://www.lqm.co.uk/training/gisintro

    In addition, we have confirmed the dates for all our courses for Spring and Summer 2017.

    We have also resurrected the one-day Introduction to Contaminated Land which is ideally suited for those new to the area of contaminated land or time-short requiring only an overview of the process, details at http://www.lqm.co.uk/training/intro/

    Our usual courses (5-Day Series, Chemistry, CLEA and Hydrogeological Risk Assessment) are also available full details at: http://www.lqm.co.uk/training/
