Every environmental consultant involved in assessing the risk to controlled waters will be familiar with the Environment Agency’s preferred assessment tool, Remedial Targets Methodology Worksheet or RTM for short.
It’s always been our opinion that you would have to try hard to design a less user-friendly piece of software. It is, frankly, a stinker. You might say that we shouldn’t complain since it is provided by the Environment Agency free of charge. But we believe that we can, and should, do better. So we have taken the methodology/models used in RTM and we have built them into a modern, user-friendly application. Key improvements include
– Input parameters read/calculated directly from the project database;
– Runs parametric/sensitivity studies for each model;
– Assesses variation in receptor concentration v time for each model for multiple contaminants;
– Assesses variation in receptor concentration v distance from site for steady state conditions for multiple contaminants;
– Automatically exports results to individual spreadsheets for each contaminant and each set of parameters;
– Automatically creates a detailed pdf report for each model.

Something is stirring deep in the Cotswolds….
It may not be quite as lucrative as hitting black gold, but it’s still mighty satisfying to ‘strike’ water as we successfully carry out another water well installation for a private client.
Our Comacchio rig drilled through nearly 40m of clay and limestone in around 4 hours before reaching a productive aquifer. Once we’ve finished installing the well casing and pump, the high quality water it produces will be used to supply an ‘eco-house’ being constructed on the site.
If you are interested in having your own water well installed then please contact Duncan Eastland – 01296 739431 – for more information.
Following on from our best year in a decade and with a burgeoning portfolio of future orders, we are looking to recruit. We’d love to hear from anyone (well, anyone except recruitment agencies) that would like to join us. Specifically, we would like to hear from you if you fit the following:
Staff Consultant – You will probably have 3-5 years experience working in the geotechnical or environmental consultancy sector and will be looking to broaden your experience and take on more responsibility. You will relish a flexible working environment and will want to work for an organisation where you efforts are recognised and rewarded.
Graduate Consultant – You will have a degree in Earth Sciences or similar and be looking to apply your knowledge in a highly practical, pragmatic consultancy environment.
Lead Driller/Second Man – We are looking for either a lead driller or a second man to work with our Comacchio rotary drill rigs. You will have an NVQ in Land Drilling plus a minimum of 3 years relevant experience (Lead Driller role).
All the positions are based at our Stoke Mandeville office but will involve working away from base from time to time. For further information, please email your CV together with a covering letter to Duncan Eastland.
Note to Agencies: It is our company policy to not use recruitment agents. You do not have our permission to re-advertise these roles and you should not contact us offering your services.
Clegg Impact Hammer
Let’s face it, sometimes you just need CBR results fast. Really fast. Maybe you need to identify any soft spots in a piling mat or in a road sub-base before the compaction plant leaves site. Or – be honest – maybe you just forgot to get the required testing done in time. Either way, we have a solution for you. We can test your sub-base using our Clegg Impact Hammer, typically completing 80+ tests in a day with results available immediately. Although the CBR value measurements aren’t as accurate as those obtained from a conventional test, we reckon they are acceptable for about 90% of the enquories we receive.
For further information please contact Steven Partridge – 01296 739413

Well, in our case the answer is very safe indeed. We’ve just completed our annual HSE audit, carried out by an independent auditor on our clients’ behalf, and scored a record 93%.
The auditors praised PrismERP, the IT system we have developed over the last decade for both managing HSE and integrating it into every aspect of our operations. With further upgrades to PrismERP planned for the coming year, we are determined to get an even higher score next time round.
PrismERP is commercially available. If you’d like to know more about how it might help your organisation please contact Duncan Eastland.
Another post discussing the joys of working at a busy airport. This time we were asked to advise on the allowable bearing capacity for a foundation to be installed at 2m depth, without either excavating a trial pit of drilling a borehole.
We opted to carry out a series of dynamic probes, using our lightweight terrier drill rig, along the line of excavation, using the data to calculate an equivalent SPT ‘N’value and thence an allowable bearing capacity. We were able to provide our client with results in real time, ensuuring there were no delays to the construction programme.
Maybe we are cynical but we usually reckon we can rely on the weather to be cold and raining, or even snowing, anytime we are asked to carry out sitework at night. So it made a pleasant change to find ourselves at the end of Runway 27R at Heathrow on a warm summer’s night last week. As a Heathrow Approved Contractor we’d been asked to carry out some urgent groundwater assessment work and because our staff and vehicles hold ‘access all areas’ passes for Heathrow, we were able to be on site quickly and with the minimum of fuss.

The latest prosecution by the Environment Agency of a filling station operator has resulted in a record fine of £8 million. The Environment Agency’s investigation found the leak resulted from the operator’s failure to address a known issue with the fuel delivery system and an inadequate alarm system. It was compounded by “poor” emergency procedures. The leak affected local residents and local watercourses, with leaked fuel entering the Langwood Brook resulting in fish kill. County councillor Albert Atkinson, deputy leader of Lancashire County Council, said: “The fact the leak was allowed to continue for more than 24 hours undoubtedly contributed to a risk of harm to people living and working nearby, as well as emergency services attending the incident.”
We believe that this case marks a change in approach from the Environment Agency, with a focus on prosecution under health and safety legislation rather than the available environmental regulations. The resulting fine of £8 million was significantly higher than fines levied for similar incidents prosecuted for polluting controlled waters.

Terminal Four at Night
Working ‘airside’ at Heathrow Airport is always a challenge, but when our client contacted us requesting plate bearing testing of the ground prior to them lifting a new chiller refrigeration unit using a mobile crane at Terminal Four we were happy to help.
The only kind of chilling our engineer enjoyed was the cool breeze while he worked through the night to ensure our testing was completed safely, on time and on budget, allowing the aircraft stand to open in time for the first plane arrival.
Pile Probing – London
We were contacted by one of our regular clients with an urgent request to carry out pile probing at one of their sites in London. We were able to be on site the next day, using our Geoprobe rig to clear 55 pile locations to a depth of 4m, all before 3pm. To make matters even better, the sun shone all day.
For more information about our pile probing service please contact Duncan Eastland – 01296 739431
