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.

QGIS 3: Creating Efficient Workflows for Contaminated Land Problems using QGIS

Contaminated land or environmental specialists need tools that enable them to effectively interrogate, interpret, evaluate, present and report the large amounts of data produced during site investigations and remediation projects. This is important to provide timely and productive outcomes for clients, regulators and wider stakeholders. Well evaluated data can ensure data gaps or deficiencies, which often delay projects, are identified earlier and can be more cost effectively remedied. Such a joined up approach can also help mitigate against the risk of litigation proceedings or lengthy regulatory intervention later down the line. Therefore, data analytical skills can help raise productivity, provide innovative solutions 'on-the-fly' and lead to better investment decisions.

Utilising suitable tools such as Geographic Information Systems (GIS) are vital to ensure you meet the current standards for data collection, visualisation, data analysis and dissemination of information as required by key standards such as BS ISO 18400‑104:2018 'Sampling Strategies' (and other members of the BS ISO 18400 series) and BS 10175:2011+A2:2017 'Investigation of potentially contaminated sites'.

QGIS is a tool that can help visualise and analyse contaminant data, investigate relationships with other spatial information, such as buildings, features shown on historic mapping. It can also investigate temporal changes in key parameters such as groundwater levels, ground gas and air monitoring datasets. Where remediation is required, if GIS analysis can show that the contamination is localised, and particularly when a credible source can be identified, then more sustainable, cost effective and targeted solutions can often be designed and communicated to clients and regulators.

Using QGIS 3+, a free and open source GIS, this one day hands on course will focus on creating a GIS workflow (model) using one (or more if time allows!) of the contaminated land problems investigated and geoprocessing skills you develop on the QGIS2 course. You will primarily be using the built-in Graphical Modeler which allows you to automate complex GIS workflows rather than manually running through individual repetitive or difficult to remember steps. Therefore, this course is ideally suited to QGIS contaminated land and environmental practitioners who have attended the QGIS2 course and/or those with the neccessary QGIS experience who wish to more efficiently design their site investigations, process, interrogate, evaluate, report and their site investigation or monitoring data and effectively communicate project specific constraints to their clients.
For example, learn how to generate and style the temporally varying raster and vector layers displayed in the video below in a matter of minutes rather than hours using a reproducible GIS workflow that you can reuse on other projects and sites. Extrapolate your skills to other time-consuming problems.

The course will involve hands-on experience with the QGIS 3+ software to include some or all of the following:
  • understand the GIS steps needed for a specific problem (break down the problem);
  • specify a GIS workflow with the required inputs and algorithms (design a solution);
  • create a working GIS model using generic inputs (provide a reproducible solution);
  • simple interpolation techniques (e.g. TIN, IDW) for groundwater contouring;
  • display 3D datasets (e.g. LiDAR and DEMs) and overlay some of your datasets;
  • create informative map infographics for your reports (e.g. maps, graphs and statistical summaries);
  • efficiently create infographics by using your own templates (Print Layout);
  • display and interrogate time-series data from within your GIS (e.g. continuous ground gas concentrations);
  • create an animated graphic or video (e.g. ground gas concentrations, groundwater levels, groundwater plume).

Delegates will need to bring their own laptops (large display screens recommended) with the QGIS 3+ software installed and ready to use (if this is a problem, please give us a call on 0115 7484080). Full joining instructions including details of which QGIS install version we will be using will be sent to each delegate prior to the course.

By the end of the course you should be better able to:
  • to create reproducible GIS workflows across sites and for colleagues;
  • solve contaminated land problems more efficiently;
  • extrapolate learning outcomes to your site specific problems;
  • streamline your data analysis, evaluation and creation of outputs for your reports;
  • inform your clients and regulator about the results of your site investigations.
  • communicate information - not just meaningless data!
All delegates will be issued with a Certificate of Attendance – which should be retained and used to provide evidence of CPD activity when required by employers or professional bodies.

This course follows on from and builds on the learning outcomes of the QGIS2 course, so attendance on that course is also recommended. Not suitable for QGIS1 level delegates.

The course will be of relevance to:

  • Consultants & SI Contractors
  • Regulatory and local authority staff involved with contaminated land issues
  • Anyone producing contaminated land reports
  • Anyone reviewing third party reports
  • Problem holders and developers seeking to improve information and sustainability from their costly SI works

June 2019

"A really useful 2 days. Thanks very much!" (Consultant)

"Useful to see the ideas for how to use Graphical Modeler" (Consultant)

"The presentation and coordination of structured practicals and thorough details was good" (PostDoc Researcher)


February 2019 (QGIS2)

*** LQM response based on QGIS2 feedback: HENCE THIS NEW has been added ***

"The course really is good with some great content that is very applicable and will change the way we design SI’s, interpret, store, and present data" (Consultant)

"With so much quality content and some not-so-simple concepts and tasks it really would have been great to have had it spread over at least two days!" (Consultant)

"Really great content, very applicable and useful. Would love to come back and spend a full day on the second half of the day!" (Consultant)

"Topics covered and detailed demos" (Consultant)

"Expanded existing knowledge of QGIS" (Consultant)

"Good overview of what QGIS can do, but too much for 1 day really, training could easily be spread over 2 days" (Consultant)

"Excellent practicals and demonstrations. A lot of information and topics to cover in one day" (Consultant)

"A QGIS3 course may help spread the content and give time for experimentation before moving on to the more difficult topics" (Consultant)

"On hand help and advice, but needs a 3rd day!" (Consultant)

"Very relevant information, learnt a lot" (Consultant)
