CP051   Quality of Water Treatment Chemicals Water Treatment
Over 80 European standards (BS ENs) for water treatment chemicals and filter media have been adopted, based largely on the requirements for "toxic substances" in the 1980 Drinking Water Directive. Revisions of standards in line with the Directive are being considered within Europe.

Unnecessarily stringent product specifications could cause costs to increase with no benefit to public health. In addition to having adequate product specifications, quality assurance systems need to be in place to ensure the quality of products used to treat public drinking water supplies and avoid possible contamination or delivery of the "wrong" product.

This project undertaken by WRc for a group of nine water utilities and manufacturers examined the quality of products currently used and the implications of possible changes to BS ENs. It identified best quality assurance practice and developed a Quality Assured (QA) audit system to demonstrate that effective quality control is practised - from point of manufacture to point of use.
