Water Chemistry (AQUACHECK)

"In continuous operation since 1985, and still the industry-leading water chemistry proficiency testing scheme…" The LGC AXIO AQUACHECK scheme is an industry-leading, global water chemistry proficiency testing programme that has been in continuous operation since 1985 – providing an extensive range of test materials for the analysis of major inorganic and organic analytes, metals, phenols, organochlorine pesticides, and many other chemical compounds found in water.

Each water source requires regular analysis to determine its safety and suitability for use, and more than 8,000 laboratories around the world choose AQUACHECK because of the extremely broad choice of water types, samples and analytes it provides. Encompassing potable, surface, ground, waste, effluent sludge, recreational, and marine waters – as well as around 100 samples and approximately 1,000 analytes – AQUACHECK can provide any laboratory that analyses water with a sample to meet its needs. Participation in AQUACHECK not only enables laboratories to identify problems before they affect water safety and quality: it also gives independent confirmation that they are producing accurate and meaningful results.
