Analyzed by an outside accredited laboratory.
At the exit of water treatment plant.
Not detected, lower than the detection limit method.
Detected, but cannot determine quantity.
Notes:
1:
Esthetical or organoleptic reasons.
2:
Turbidity must be equal or under 5 NTU and must not overpass 1.0 NTU for more than 5 % of total measures
taken within 30 days.
3:
The annual mean concentration of total THM (chloroform, bromodichloromethane, chlorodibromomethane and
bromoform) must not exceed 80 µg/L (samples taken at the end of drinking water distribution network).
4:
ABS: absence.
5:
Health reasons objectives.
6:
Maximum obtained for a sampling site.
7:
Lead and copper level at the center of water distribution network. When water samples are taken from old
pipes (before 1970) results are shown below.
