The WHO guideline values are of worldwide application. The EC Directive applies only to member states of the European Community. The Directive sets numerical standards for health related chemical parameters, along with standards for a number of indicator parameters. The unit of measurement and the notation for a particular parameter can vary between the above standards. The WHO Guidelines and the European standards use a mixture of mg/l and μg/l, while the USEPA standards are mainly in mg/1. The levels of monitoring and analysis required for chemical parameters are described. It examines the microbiology of water and the most common waterborne diseases; the requirements for the bacteriological quality of drinking water; and the testing of water for pathogenic organisms
