Interpretation of Water Quality Samples

Lindsay McMillan, PhD researcher at Birmingham University, will be presenting the findings of her research at two of Waterra In-Situ's groundwater sampling courses in May.


You may remember that Waterra In-Situ, along with the Environment Agency, provided support funding to a NERC PhD case studentship study. Our researcher, Lindsay McMillan, has studied advances in the improved accuracy and reliability of methodologies and equipment for groundwater sampling from long-screen monitoring wells and boreholes.

Lindsay will be presenting insights into her research under the title "Interpretation of Water Quality Samples from Long Screened Wells" as part of Waterra In-Situ's "Groundwater Sampling - Methodology and Equipment" training courses being held in Birmingham on the 16th and 17th May 2012.

The training course looks in detail at the equipment and methodologies available for effective sampling and includes hands-on demonstrations of a wide range of pumps, bailers and passive sampling devices.

Optical Dissolved Oxygen Probe For DO Monitoring

Waterra In-Situ announces the launch of the RDO^® PRO Optical (DO) Dissolved Oxygen sensor into the UK and Irish marketplace!

The In-Situ RDO ^® Optical Dissolved Oxygen sensor offers superior performance over traditional membrane-style DO sensors (based on a rigorous US Environmental Protection Agency ATP process) across a range of factors including:

• Speed of response


• Sensitivity


• Accuracy in low DO conditions

The RDO ^® PRO sensor features a highly robust design that allows it to be deployed in conditions of high salinity and harsh process monitoring environments such as dam discharges and wastewater treatment plants.

The probe can be supplied in single parameter DO probe format ready for connection to existing process control or logging systems, and as an option in our TROLL ^® 9500 multiparameter water quality instrument.

Peter Dumble, Waterra In-Situ's Technical Director, believes that the sensor is an excellent addition to the company's water quality monitoring range.

"The new sensor offers extremely stable measurement capability, which makes it ideal for long-term deployment.

I am impressed by its ability to hold and maintain calibration. Compared to traditional DO probes, te RDO is a real pleasure to work with in field conditions providing cosnistently reliable results for extended monitoring prgrammes."

James Sorensen - Guest Speaker

We are delighted to have James Sorensen of the British Geological Survey as a guest speaker on our NEW data logging CPD course.

In-Situ Rugged TROLL
Water Level Loggers

James Sorensen from the British Geological Survey will be a guest speaker at our 1 day CPD course on "Water Level Measurement using Data Loggers" in Birmingham on 28th March 2012.

James will be giving us an insight into "Logger Accuracy and the Need for Industry Standards" based on research he recently conducted for a recently published paper in Groundwater Monitoring Review (Sorensen & Butcher 2011). His findings showed the inconsistency in results across a sample of device from 14 leading brands and highlighted poor calibration and drift as being key problems.

The Waterra In-Situ CPD course provides a practical guide to using data loggers inb the field, stressing the importance of good field practice and with some useful insights on how to improve data accuracy. Delegates will discover how both vented (gauge) and non-vented (absolute) pressure loggers work, understand how to set them up and use them most effectively and find out how to overcome common problems.
