Within this proficiency test your testing ability for organophosphorus pesticides in waste water will be evaluated. As a result your wider quality assurance activities can be informed, from which to ensure only high quality test results are achieved as part of your testing arrangement.  

The quality of drinking water is highly regulated across the world. Chemical contaminants such as heavy metals or pesticides might have long-term health implications. Other chemical contaminants are indicators of environmental pollution at source. Fapas drinking water proficiency tests provide whole volume drinking water samples with a wide range of routine and non-routine chemical components.

Organophosphorus pesticides are used extensively within agricultural practices to ensure produce is of high quality, while maintaining a large yield. This can lead to potentially high levels of these pesticides running off into water treatment systems. This can potentially affect the quality of the treated drinking water that is passed to consumers. Hence effective testing measures are required to highlight these high levels and inform water treatment strategies.

Proficiency testing measures from Fapas make use of real food matrices, from which to highlight areas of improvement within your current testing arrangement. This is in addition to safeguarding your current analysis accuracy, from which to satisfy regulatory bodies of your current testing ability.
