Pneumatic Slug Testing: An New Approach for Hydraulic Conductivity Monitoring?

Conventional slug testing offers some major advantages over pump tests in site investigations but there are some issues associated with projecting slug test permability values to larger aquifer volumes. Could pneumatic slug testing provide an alternative?

Slug testing using a known volume of water or an item that displaces a measured volume has become a standard tool in the hydrogeologist's or engineer's kit bag in recent years. The approach offers a number of advantages over standard pump-based tests because it is easy to implement in the field, offers large cost savings, and it will work in low flow environments.

Conventional slug testing has improved our ability to determine hydraulic conductivity, and consequently made a major positive difference to site characterisation across a range of applications. However there are some drawbacks, particularly related to the need for the insertion of a water sample or a solid slug. For instance;

• The pressure wave caused by insertion may impact data accuracy.


• Slugs may not manoeuvre around well or borehole casings


• It may be difficult to deploy a slug large enough to create sufficient displacement for measurement.

Pneumatic slug testing offers an interesting new option to overcome these issues because, as the name suggests, no physical slug is used. Instead the well or borehole is sealed and air is used to pressurise the water column. When equilibrium is reached between the pressure in the water head and the well then de-pressurisation takes place and a data logger can measure the resulting changes in water level.

Apart from removing or reducing the problems associated with physical slug insertion, pneumatic slug testing also provides near instantaneous slugging events, which is very important in achieving the best possible accuracy.

Waterra In-Situ Technical Director, Peter Dumble, believes that pneumatic slug testing will in time become a preferred mechanism for monitoring hydraulic conductivity in monitoring wells and boreholes.

"This method of hydraulic conductivity testing has some clear advantages over both pump testing and conventional physical testing. In the short term I can see some important niche applications for the approach and over time we are likely to see it become the method of choice in the industry"

Waterra In-Situ - For a full range of oil water interface level meters

Monitoring water and DNAPL levels in real-time

Monitoring DNAPL levels in real-time has always been a challenge. Now with the help of the In-Situ Level TROLL® 500 instrument there is an effective way of keeping track.

DNAPL (dense non-aqueous phase liquid) contaminants have the unpleasant property of sinking below the water table and creating the potential for long term environmental problems.The difficulty for organisations who are engaged in the monitoring or remediation of brown field sites is that DNAPL materials such as chlorinated solvents, creosote or oils are simultaneously very common but have a slow migration profile. As such the impact on aquifers may take some time to show through.

The Level TROLL® 500 instrument provides an accurate method of providing data on the thickness of DNAPL levels in real-time and, if required, over the long term. The installation requires two devices; one for the DNAPL layer and the second in the water column. This allows the thickness of the DNAPL layer to be calculated by comparing the difference in density between the two liquids.

The Level TROLL® 500 has some very important features that allows it to cope with hostile conditions and remain operational for an extended period ;

• Titanium casing


• TROLL® Shield antifouling system


• A battery pack with typical life expectancy of up to 10 years

Waterra In-Situ Technical Director, Peter Dumble, believes that this use of the Level TROLL® 500 could have some important benefits in the remediation sector:

"Without a clear understanding of a site's DNAPL profile it is very difficult to choose the most appropriate remediation technique. What we have here is a mechanism that maximises the chance of getting it right first time."

To find out more about the DNAPL measurement procedure and the layer calculation equation download our datasheet (PDF opens in new window), take a look at the Level TROLL® 500 page on our website or call the Waterra-In-Situ's technical support team today on +44 (0)121 733 7743.

Low Flow Sampling with Advanced Data Outputs

Waterra In-Situ's new Low Flow System combines advanced low flow groundwater sampling capability with accurate and timely reporting functionality.

Low Flow System in Action

The system comprises a TROLL® 9500 Water Quality Instrument, RuggedReader® Handheld PC, a flow-through vessel with baseplate, Flow-Sense Software, and other accessories.

The core benefits of low flow groundwater sampling are supplemented by sophisticated data collection, monitoring and reporting features. The ability to automatically collate well and pumping information, set stability limits on key water quality parameters, and automatiacally record calibration and sampling data simplifies quality control AND improves conformance to regulatory standards.

Peter Dumble, Waterra In-Situ's Technical Director and Hydrogeoloist, sees the system as a major step forward:

"The technical case for low flow purging prior to groundwater sampling is well established for use in short-screened monitoring wells and boreholes and has been given increased prominence in the recent update of BS10175:2011 for use in contaminated land investigations. 

This system provides an elegant operational tool for adopting and recording the whole low flow sampling process. Engineers, consultants and hydrogeologists will welcome both the reduction in the time it takes to create base reports and the improvement in quality control and accuracy of the process."

The system is easy to set-up and operate and is available to purchase or for rent. You can see just how easy it is to use by looking at the video below.

Easy Load II Peristaltic Pump - Now Available

Easy Troll II - Peristaltic pump

Waterra-In-Situ is delighted to announce the introduction of the Easy Load II peristaltic pump to its product portfolio.

The Easy Load II is ideal for low flow groundwater sampling at depths of up to 8 metres of ground surface. It is also designed for surface water and gas sampling applications.

The most striking feature of the Easy Load II is the simplicity with which sample tubing can be changed. It takes seconds to swap one set of tubing with another - a real time advantage when in the field compared to competitor models.

Easy Load II - Field set up

A key benefit of peristaltic pumps is that they offer highly consistent sampling integrity because samples are retained within the pump tubing while being moved by a mechanical squeezing action.


Waterra-In-Situ is offering the Easy Load II in a range of 3 kits - standalone, with/without a field case and with/without a rechargeable battery pack. High quality platinum cured silicone tubing ensures sample integrity - particularly for VOC's.


For more details of the Easy Load II and our wide range of groundwater monitoring pumps call our technical support team today on +44 (0)121 733 7743.

Successful Groundwater Sampling Training

Tim Davies shows off
the Powerpack PP1
actuator

We have had some very good feedback from the CPD accredited groundwater sampling training courses that we ran at the end of March.

In purely quantitative terms the overall average score given by delegates was 1.5 where 1 = Excellent and 5 = Poor.

Qualitative feedback was very encouraging too. Here are just a couple of comments that we received;


’Very informative, broad and answered all questions fully. Given me a lot to think about in terms of QC – thank you’.


‘Very worthwhile, learned a lot about sampling methods and pleased with certificate!’


The Waterra team really enjoyed the opportunity to interact with such a diverse group of clients from the groundwater monitoring sector. Amongst others we had representatives from the water supply industry, nuclear energy, environmental consultancy and landfill monitoring. There was an interesting interchange of ideas between delegates and, for the presenters, some challenging questions too.

Kayleigh Smith
demonstrates
the TROLL 9500

We had the opportunity to show off the TROLL 9500 water quality instrument for the first time, and the delegates were very impressed with its multi sensor, low flow sampling and reporting capability.

Providing hands-on demonstrations in the training room is a powerful way of showing off different sampling techniques. However at the Beckett's Farm training centre we also have the benefit of an on-site borehole where we can demonstrate pumps and other downhole equipment in a field environment (hardly realistic as it's sited in the car park - so no mud!).

Our next groundwater sampling training session is set for September 7th 2011 - check out the training page on the website for more details or call our technical support team today on +44 (0)121 733 7743.

Groundwater Quality Research Project

A strong start has been made by Lindsay MacMillan, the University of Birmingham PhD student, on her research project "Groundwater Quality: Rigorous sampling and interpretation of long screen wells."

Research into technologies and techniques

Waterra, along with the Environment Agency, are providing industrial support funding to this NERC PhD case studentship sstudy because it promises to explore how advances in methodologies and equipment can enhance the accuracy and reliability of groundwater sampling from long-screen monitoring wells and boreholes

Lindsay has been busy putting in place her PhD plan and developing the literature review that underpins all research of this kind. She has also started work on a set of activities that should help to answer the fundamental question of "how can existing data acquisition and interpretation be improved".

Academic and hands-on

Activities include developing and validating a conceptual model to test sampling methods and investigating new data collection techniques. The research phase has seen Lindsay go on field sampling trips with various local authorities as well as attending Waterra's groundwater sampling and groundwater dataloggers training courses.

Peter Dumble, MD of Waterra UK, commented that: "It's great to have an objective review of the issues surrounding both long screen monitoring and new sampling techniques. Lindsay's work is forming the basis of new guidance for this area and I am delighted that she is combining both academic rigour and field sampling experience to set out her project."

Water Framework Directive

The importance of this research is underpinned by the continued roll-out of the Water Framework Directive, which is increasing the need for operator self-monitoring. The costs of the monitoring process could be markedly reduced if long screen wells, in conjunction with techniques such as passive or low-flow sampling, can be shown to provide reliable results.

For more information on new groundwater sampling technology Waterra website or call our technical support team today on +44 (0)121 733 7743.

Dry land rowing - £1,000 raised

Elaine and Peter Dumble -
not getting their feet wet

Further to our recent post about a charity indoor row we are delighted to announce a very successful result!

Peter Dumble (Waterra UK MD) and his wife Elaine both completed 10km in under an hour.  This means that they raised just under £1,000, which was way beyond anything they had expected to achieve.

Peter and Elaine want to thank to everyone who made pledges and donations to their charity effort.  All proceeds are going to The Stroke Association (stroke.org.uk).

Why Multilevel Monitoring?

Multilevel monitoring, in our experience, doesn't always get the attention it deserves in the industry.

It isn't as if the UK doesn't have examples of sub-surface structures that encourage a variety of groundwater flows. We also have plenty of examples of cross-contamination because of complex site conditions. Perhaps it is lack of familiarity with the equipment available?

You can imagine that we were pleased to see that several of the speakers at the recent Solinst Symposium 2010 provided insights into the role and practice of multilevel monitoring. The importance of getting detailed site characterisations to support effective decision making was an on-going theme, and there were a number of examples of how limited investigations failed to identify contamination sources accurately. Beth Parker, of the University of Guelph, provided an insight into her detailed research into groundwater flows in fractured substrates: the highlight being that contamination plumes expand more slowly where fracturing is densest

As you can tell Waterra is enthusiastic about the benefits of multilevel monitoring and we have many years experience in supporting our customers with products and training to back it up. For more information on how we can help you choose the right approach call us today on 44 (0)121 733 7743.

Dry land rowing - for a good cause

Peter and Elaine Dumble.
The next challenge is a 10 km row

As a highly qualified and extremely experienced hydro-geologist and MD of a groundwater sampling equipment company you'd expect Peter Dumble to be something of an enthusiast for all things water related.

So it it might come as a surprise that Peter, and his wife Elaine, are taking part in a 10 km row for charity...on dry land!

Peter and Elaine are fundraising, as part of the Solihull Goldies, for The Stroke Association (stroke.org.uk) and are hoping that public generosity will be sufficient incentive for them to achieve 10 km each.

The Waterra UK team have their own explanation for the non-aquatic nature of the event.  An unknown commentator suggested, "Peter couldn't complete 10 km on water because he wouldn't be able to resist testing out the Telescoop water samplers and stream flow meters."

Donations are gratefully received and can be made online at the Justgiving website.

Peter and Elaine would like to remind you that if you suspect a stroke - ACT FAST.
