Apart from monitoring studies and scientific research, most water withdrawals result from the application of legislative and regulatory texts aimed at public hygiene, pollution control, the monitoring of classified installations and treatment plants, water policing, etc.

The taking of a water sample is a delicate operation to which the greatest care must be given; it conditions the analytical results and the interpretation that will be given. The sample must be homogeneous, representative and obtained without modifying the physico-chemical characteristics of water (dissolved gases, suspended solids, etc.). Since in most cases the analyst is not responsible for the sample, it is appropriate that the sampler has an accurate knowledge of the conditions of the sample and its importance for the quality of the analytical results. 

Overall, it is therefore necessary to set up a structured organization, have qualified staff, develop a methodology adapted to each case, proceed with a judicious choice of sampling points and use the appropriate equipment. In any case, the results of the analysis will only be usable if the sample is representative.
