| Definitions |
- Desired Maximum Value (DMV). |
- Extinction of the Desired Maximum Value (DMV) and replacement by the Maximum Allowable Value (MAV). |
- It improves definitions of drinking water, control and surveillance of water quality for human consumption.
- Adds definition of alternative supply solution, cyanobacteria/ cyanotoxins. |
- They are maintained. |
- Definition of drinking water and water for human consumption, potability standard, organoleptic standard, treated water, individual, collective alternative solution. |
| Parameters |
- Total of 36 microbiological, physical, chemical and organoleptic parameters: 12 organic substances, 10 inorganic substances and 14 organoleptic substances. |
- Potability standard divided into 3 categories: physical, organoleptic and chemical characteristics (4 physical categories, 10 components affecting organoleptic quality, 31 chemicals, 11 inorganic and 20 organic substances, including disinfection by-products); bacteriological characteristics (tolerant to thermotolerant coliforms) and radioactive characteristics. |
- Distinct microbiological standard for drinking water, at the treatment station outlet and distribution system.
