Test Description

The drinking water industry is highly regulated across the world. There is a related responsibility to ensure that the source of the water has a low environmental pollution. Fapas surface water proficiency test samples replicate those used to test for potential environmental contamination, covering a wide range of determinants. These include routine components and trace metals.

This proficiency test evaluates at your testing ability for major inorganic components, from which to critique your training methods from which to ensure high quality testing measures are offered to your customers.

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.

Surface water is taken to mean water sourced from rivers, lakes or reservoirs.     

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
