The realization of periodic analyses is necessary to certificate the good functioning of the system and the compliance of the sanitary quality criteria in water. These analyses are carried out in the laboratory and measure chemical, physical and biological parameters of the tap water to be suitable for the human consumption. The analysed parameters are:
- Microbiological parameters ( Escherichia filters, Enterococ, Clostridium perfringens ...)
- Chemical parameters (benzene, cadmium, mercury, cyanide...)
- Indicatory parameters (chlorine, conductivity, smell, pH...)
The citizenship can consult the quality of their home’s water in two ways:
1. Asking for an analytic of control to the Agency of Public Health.
2. Or making contact with the supplying company, Waters of Barcelona.
