Explanation:
1. (*) Level of inspection:
a) Level I: Including parameters to be inspected prior to use and then inspected once every 6 months. These are parameters that can be affected by the weather; and the water supply units and the public health units in localities can carry out. The inspection of water quality basing on those parameters helps in the monitoring of the treatment process of the supply stations as well as in the change of water quality in individual households water supply in order to find measures to correct timely.
b) Level II: Including ‘parameters’ of requiring modern equipment for inspection and little fluctuation due to the change of weather. These parameters are inspected at these times:
- Before the use of the water source.
- Water sources exploited in areas with high pollution potential of relevant elements or elements already existed in nature.
- When the results of water cleanliness inspected or epidemiology survey shows that water might be contaminated.
- When an evironment crisis occurs affecting the cleanliness of the source of water.
- When there are doubts that water is contaminated due to the presence of the elements presented in the above table.
- Other special requirements.
2. (**) Specifically for the parameter of pH: the permissible range would be from 6,0 to 8,5.
