The quality of drinking water is highly regulated across the world with chemical contaminants such as heavy metals or pesticides thought to be responsible for long-term health implications. Some chemical contaminants can be indicators of environmental pollution at the source of drinking water, which can have large implications on both the safety of the water and the overall quality. 

Fapas Drinking Water proficiency tests provide whole volume drinking water samples with a wide range of routine and non-routine chemical components to challenge your testing practises to inform your quality control processes, maintain your testing accuracy and promote continuous improvement over a large number of analyte/matrix combinations.

Routine components can be seen in every day testing, and as such it is key to ensure effective quality processes to maintain accurate testing across the potential contaminants that are looked at the most.
