Traditionally, water chemistry has been measured by taking spot samples, either manually or using autosamplers, transporting to a laboratory where the samples are then analysed. In situ analysis removes the logistical problem of transporting samples, meaning larger data sets can be obtained. The quality of data can be higher by removing the risk of sample deterioration or contamination. Furthermore, it raises the possibility of large scale networks of sensors deployed on moorings and auton...

Affinity Water's 36 Ml/d output karstic groundwater site in Hertfordshire abstracts from four boreholes which are then blended and treated at the works. All four sources contain metaldehyde, some at a constant low level and others at highly variable and rapidly changing concentrations. Affinity Water and Anatune Ltd have developed an application of an Agilent Technologies Triple Quadrupole GCMS instrument with GERSTEL automated sample preparation and sampling to take quasi real-time sample...

The UKAS perspective including special reference to the SCA Inorganics and Metals working group

This presentation will aim to summarise the recent work carried out across three distinct working groups covering the organics subcommittee as well as the ad hoc groups responsible for production of guidance documents on both sample stability and uncertainty of measurement estimations for regulatory drinking water analysis. The work of the organics subcommittee has been at the core of SCA since its inception in 1972 and it's fair to say that the technological advances made in this area in...

Mechanisation, industrialisation and more recently automation and remote operation have been transforming manufacturing and food production for the overall benefit of societies for a long time. Industrialisation through innovation and in particular the conception and application of new technologies has improved life significantly for centuries. The production of drinking water has similarly been transformed from a general philosophy of treatment facilities being locally managed and operated t...

The SCA story: - Past, present and potential future

Defining the SCA's priorities

Chemical analysis of soils and associated materials

The Data Science Revolution Data comes from many sources: from the results of water analysis to the time, date and location of a customer complaint. The ability to turn data into information is determined by: the skill of wrangling data (also making sure the data is in an appropriate electronic format that can be used in the first place!) checking the data is not random and maximising its value; and delivering the findings in a format that is accessible and can be clearly underst...

Increasingly stringent legislation in the European Union has driven down SO2 emissions on many processes from the 100's mg.m-3 to the 10's mg.m-3, or in some cases even lower. Consequently, the measurement challenge to accredited providers of compliance measurements and EN 14181 QAL2 calibrations has become increasingly difficult, and meeting legislative uncertainty requirements far from a trivial matter. We take stock of current capability for measuring this important pollutant and present s...
