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.

Perchlorate dissolves easily, is relatively stable and is mobile in water. This can disrupt the normal function of the thyroid gland in both children and adults. In adults, the thyroid plays an important role in metabolism, making and storing hormones that help regulate the heart rate, blood pressure, body temperature, and the rate at which food is converted into energy. It is therefore fundamental to utilise our proficiency test to classify the quality of water. This ensures the safety of consumers’ health, as we are able to identify if the drinking water exceeds the maximum level of perchlorate.

Proficiency testing activities are important to ensure only high-quality testing measures are used to highlight any potentially unsafe levels of a range of indicator organisms within this bathing water matrix. This can allow you to highlight any potential areas of improvement within your testing solution, to maintain the high-quality testing abilities your regulators, currently enjoy.
