Test Description

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.

Within this proficiency test your testing ability for major inorganic components within drinking water will be evaluated. This can allow your testing methods to be critiqued and evaluated, from which to inform strategies to maintain the high quality test results required by your customers and regulators alike.

Major inorganic compounds are found within our everyday drinking water supplies. This can be as a result of plumbing materials used within pipes, as well as the treatment process. As such it is important to highlight any high levels as this can have dramatic effects on taste and colour of drinking water, as well as the product safety.

Drinking water is integral to our everyday lives, as such it is vitally important to ensure high quality testing is used to highlight any potentially unsafe drinking water that may be exposed to consumers to cause potential harm. These testing methods must be rigorously scrutinised to ensure they are fit for purpose. Fapas proficiency tests can form the benchmark of these activities.

Fapas proficiency testing measures can highlight any improvements that may be required, as well as informing any subsequent quality assurance activities. Fapas proficiency testing measures can challenge your testing activities in much the same as routine analysis, therefore providing direct comparisons from which to ensure your results are highly credible and repeatable
