The Environment Agency (EA) has created a new National Water Quality Instrumentation Service (NWQIS) to improve water quality monitoring in England and Wales.
The body is part of the National Laboratory Service and will fulfil the field monitoring requirements of the EA.
However, it will also be available to other Public and Private sector organisations.
Chris Hunter has been appointed to manage the NWQIS.
He says: 'The new service will centralise the Agency's water quality instrumentation activities to deliver several important benefits.
'For example, there will be greater commonality amongst both the instruments that we use and the procedures that we use for set up, calibration, operation and service.
'This will lower costs and improve data accuracy and repeatability,' he added.
Under the European Water Framework Directive, the EA is responsible for monitoring the quality of groundwater and surface waters such as rivers, streams, lakes, estuaries and coastal waters.
A wide range of instrumentation is employed for these purposes, including handheld water quality meters such as the YSI 556, logging multiparameter water quality 'sondes' such as the YSI 6600 and complete water-quality monitoring stations with communications capability to provide high-intensity, almost real-time data.
Prior to the establishment of the NWQIS, the Agency's water quality instrumentation was purchased and operated by local offices, but now, under the co-ordination of Frances Houston, all water quality monitoring equipment is purchased and managed centrally.
As Frances explained: 'This reduces the variety of instruments that we use, which helps in a number of ways.
'Firstly, it simplifies the stocking of spares and accessories.
'Secondly, it provides greater availability of spare or replacement monitors, so that we can quickly replace units that are damaged or lost.
'Thirdly, it helps us to build a closer partnership with suppliers, which means that we are able to influence future product development and finally, central control enables us to ensure that all staff utilise the most accurate and reliable instruments,' he added.
Before the NWQIS could be established it was first necessary to undertake a review of all of the EA's monitoring instrumentation, so most of it was sent to the EA's Reading offices for assessment before either reconditioning or disposal.
In recent years, the YSI 556 multiparameter water quality monitor from YSI Hydrodata (EA framework partner) has been the workhorse of the EA's water monitoring teams; Matt Loewenthal reports a typical operational lifetime of more than 10 years for the 556.
However, the agency is now moving to the newer MCERTS-approved YSI Pro Plus multiparameter water quality monitors and a full capital asset replacement programme is under way.
Matt said: 'This will ensure that our regional staff have access to the latest technology, which is provided with our own operating procedures so that we can ensure, for example, that pH is monitored in Penzance in exactly the same way as it is in Carlisle,' Matt said.
The creation of the NWQIS will also provide greater access to technology such as that which enables real-time web-enabled display of live water quality data and Matt's team has already installed monitoring systems of this nature at sites across the UK.
