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 2: Solving & Visualising Contaminated Land Problems using QGIS

BS ISO 18400‑104:2018 'Sampling Strategies' (and other members of the BS ISO 18400 series) is guidance intended to be used in conjunction with and take precedence over BS 10175:2011+A2:2017 'Investigation of potentially contaminated sites'.

Part 104 provides guidance on the development of site investigation and sampling strategies taking into account the need to obtain representative samples and to have regard to relevant statistical principles. Therefore, 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.
QGIS is one such tool that can help visualise and analyse contaminant data and investigate relationships with other spatial information, such as buildings and features shown on historic mapping. 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, which are acceptable to regulators.
Using QGIS, a free and open source GIS, this one day hands on course will provide ways to more effectively utilise your site investigation and monitoring data through a series of contaminated land problems to inform your conceptual site model, site investigation design, help to interrogate your SI data and produce informative spatial infographics and not just meaningless pages of data. In so doing you can more effectively understand and communicate the sources and risks at a site to provide more cost effective solutions - getting full value from the data for you and your clients.

The course will involve hands-on experience with the QGIS 3+ software to include some or all of the following:
  • how to extract AGS data and import it into QGIS;
  • using Query Builder to query your SI data;
  • selecting features from a map;
  • selecting features by attributes or spatial relationships;
  • using the Field Calculator to create new features (e.g. hazard quotients) or update datasets;
  • join meta data with no spatial attribute (e.g. risk assessment criteria or remedial targets);
  • merging and splitting vector layers;
  • help define your sample strategy (locations) using vector geoprocessing tools; 
  • ways to symbolise your SI data to create interpretative risk assessment maps;
  • efficient ways to style and interrogate separate contaminant specific maps;
  • undertake your exploratory data analysis using graphical tools (e.g. scattergraphs, box plots, histograms, pie charts)
  • undertake statistical analysis of contaminant datasets;
  • create informative map infographics for your reports (e.g. maps, graphs and statistical summaries);
  • display 3D datasets (e.g. LiDAR and DEMs);
  • simple interpolation techniques (e.g. TIN, nearest neighbour) for groundwater contouring.

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 use QGIS to help solve and present contaminated land problems;
  • undertake exploratory data analysis;
  • produce map infograhics showing spatial contaminant distributions and statistical analysis;
  • understand the risks to relevant receptors at your sites;
  • make more effective use of your SI data and streamline your data analysis;
  • utilise open and other spatial data sets and sources for your site investigations;
  • more efficiently present your outputs in 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 QGIS 1 course. Taken on its own it presumes some familiarity of and experience with QGIS so beginners would benefit from also taking the QGIS 1 course.

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

"A really useful day, thanks" (Consultant)

"Useful handouts, good for future reference, appreciated willingness to stay on to demonstrate features" (Consultant)

"Lots of relevant information and good pieces of information" (Consultant)

"The coordination and style of presentation was good" (PostDoc Researcher)

February 2019

*** LQM response based on QGIS2 feedback (below): NEW course QGIS3 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)
