Water is vital in sustaining all natural systems, and each source requires regular analysis to determine the safety and suitability of use. Potable water must be good in quality and quantity and free from harmful chemicals and microorganisms. Discharged water from local wastewater treatment plants and industries must comply with environmental guidelines. Process waters must be kept clean to ensure product quality. As water sources can change, regular testing is advised. 

AXIO Proficiency Testing offers the industry-leading AQUACHECK scheme that has been in continuous operation since 1985. Test materials are provided for the analysis of major inorganic/organics, metals, phenols, organochlorine pesticides, and many others. Participation in the AXIO AQUACHECK scheme allows laboratories to identify problems before they affect the quality and safety of waters. Participants will be able to demonstrate independently that they are producing accurate and meaningful results to laboratory management and customers.
