The Environment Agency’s Remedial Targets Methodology (RTM) and Worksheet provide a framework for assessing the risks to controlled waters from land contamination, and for deriving site-specific remedial targets for contaminated soils and groundwater where those risks are unacceptable.

The course is delivered over two half days (mornings); most likely 18/19 June. However, a 3rd half-day is reserved because an update to the methodology is expected but the date of the update is unknown. (It has been in the pipeline for a couple of years!) In the event the update is released very close to the course, LQM may adjust the dates to 19/20 June to give time to update the course. Please ensure you are available for all 3 dates - 18/19/20 June.

This course is a unique blend of learning the basics of hydrogeological risk assessment and doing practicals using RTM.

Come away with renewed confidence in how to tackle hydrogeological risk assessment for potentially contaminated sites in the UK.

This course can be delivered face to face or live online - if no date is shown, or is not in the format you are interested in email That will help us when planning future courses.

The course will teach delegates

  • The importance of the conceptual site model (CSM) for assessing risks to controlled waters from land contamination
  • The tiered framework for assessing risks of pollution of controlled waters from land contamination
  • Methodology for deriving remedial targets for soils to protect water resources
  • When to use the remedial targets worksheet – applicability of the models to the CSM
  • How to use the remedial targets worksheet – parameterisation; prediction; and sensitivity
Delegates will need computers (large display screens recommended) capable of running Excel with the Remedial Targets Worksheet v3.2 already loaded and ready to use.  All instructions are for using the spreadsheet on a computer running Windows.    In previous courses, mac users with Excel installed have had varying degrees of success but using a mac for this course is not recommended. 


By the end of the course you should be:
• Familiar with the sources of information available to develop an initial CSM for assessing risks to controlled waters from land contamination
• Aware of the tiered framework for assessing risks to controlled waters from land contamination and deriving remedial targets
• Aware of the types of solute fate and transport models used in each tier of the remedial targets worksheet, along with their assumptions and limitations
• Aware of the input parameters required by the remedial targets worksheet

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 is an introductory course equally suited for those without any hydrogeology background or those who require a refresher course relevant to their current job activities.

The courses will be of relevance to:

  • Regulatory and local authority staff involved with contaminated land issues
  • Consultants
  • Problem holders and developers needing a more in-depth understanding of contaminated land issues
  • Anyone producing contaminated land reports
  • Anyone reviewing third party reports

"Very informative and suitable for all levels.  A clear step-by-step approach with plenty of opportunity to ask questions which Judith spent time to answer.(Consultant)

"I learned a lot in this course, and feel like I'm now ready to apply this to real site data. The worked examples were very detailed and extremely useful. I was really pleased with how well it worked as a webinar rather than a face-to-face event, and would welcome more webinar events in the future!" (Consultant)

May 2018

"Practicals using RTM worksheets" were the best part (Consultant)   "Well presented with great patience and a sense of humour" (Consultant)   "It gave me a renewed appreciation to a number of factors. As well as understanding the pore water and how the water flow works within an aquifer, although common sense, is helpfully insightful." (Consultant)   "It was thoroughly enjoyed." (Consultant)   "Everything was well explained with enough time for questions to be answered. The practicals were pitched just at the right level and were representative of 'real life' usage." (Consultant)   "Very useful course for those wanting to get to grips with the RTM and how to use the worksheet. Thanks." (Consultant)  

November 2017

"Very happy with the course as a whole. It demystifiyed the RT spreadsheet and the thinking behind it. Links to up-to-date sources of EQS values also very useful. Judith covered everything with the right level of detail and made sure that the entire group was up to speed before moving on, making sure that no one was left behind. The material covered in the course will definitely be of use in our project work." (Consultant)

"The course was very well structured, presented and delivered. Judith is a fantastic orator!, I will be certainly registering to future LQM sessions. Many thanks" (Consultant)

"The course leader knew what we (well, at least, I) required from the course and knew how to teach it." (Consultant)

November 2016

"Learning about how the remedial targets work. The way the course was structured meant you could easily pay attention throughout the day (i.e.. theory interlaced with practical sessions)."  (Local Authority)

“The course was generally fantastic. Helpful practical's. Appropriate breaks to ask questions. The quality of the handouts were great and will be a very useful resource in the future. The course was well paced and easy to follow.” (Consultant)

"Course delivery by the trainer and one to one help offered when working through the practical's." (Local Authority)

"The practical sections were very worth while" (Consultant)

“The course being interactive, actually using the model in the course helps to retain the information much more effectively.” (Local Authority)

"The course was very well broken down and because of that it was easy to follow and motivational throughout the day. The trainer did a very good job in explaining everything even when it got complicated." (Consultant)

“The legislation/ regulatory framework was covered in sufficient detail and it was useful to know where to find the relevant standards e.g. priority substances directive and the EQS directive, etc” (Local Authority)

May 2016

“The practical sessions were very useful, and helped to further cement the application of the RTM and spreadsheets.” (Consultant)

"Enjoyed the hands-on aspects, with this sort of subject the best way to learn is to do it." (Local Authority)

“Good to spend a bit more time on the workings and information sources used in the assessment.” (Consultant)

"The amount of information covered - I feel much better informed about the whole groundwater DQRA process." (Consultant)

“The whole course was very enlightening, as I usually read the results of such assessment. It was great to see and understand the process of reaching those results. I loved the practical’s, as it felt like you could put into practice the theory.” (Local Authority)

March 2016

"A good all-round introduction to hydrogeological risk assessment. I left the course feeling confident in using RTM." (Consultant)

“I liked how we pushed through and got all the information covered.” (Consultant)

“Detailed, provided confidence in the approach to complete risk assessments.” (Consultant)

"I found the structure and presentation style of the course very good. The systematic way in which we were guided through the P20 / Hydrogeological Risk Assessment meant that I left the course having gained all the outcomes which i had hoped for. LQM trainer gave plenty of opportunities to us ask questions and was very helpful in answering as many as possible. Lunch was also very nice!" (Consultant)

November 2015

“Background to the equations used - i knew the 'how' but not necessarily the 'why'...” (Consultant)

"Overall excellent. Practicals very useful." (Consultant)

“Overview of legislation, working through of practical examples.” (Consultant)

"It was hands on, there was space for discussion and everything was explained from base principles" (Consultant)
