Potability testing of network water

Potability is defined by the European Union and WHO and currently covers 63 parameters (since 1980).
In 2003, certain parameters were lowered (nitrates, lead, etc.) while approximately twenty more disappeared from the standards…
Furthermore, in the most common analyses (those displayed in town halls), only about ten parameters are generally measured…
More than 3,000 pollutants are currently identified…

It is practically impossible to look for all polluants !

More than 900 molecules are registered in the agricultural sector! This is why the findings of the analyses are nearly always identical, i.e. : The water is compliant, in relation to the parameters measured…
It is impossible to measure something you are not looking for !

Water analyses

There are 3 types of analysis :

Bacteriological analyses

These are classified according to the nature and number of bacteria or strains sought : B1, B2, B3, etc.


Physico-chemical analyses

These measure the organoleptic characteristics (taste, odour, temperature, transparency) as well as the physico-chemical composition of water. As with bacteriological analyses, they are classified according to the number of parameters measured : C1, C2, C3, etc.


Chemical analyses

The most complex as they require exact knowledge of what is being sought to perform the measurement. Simply speaking, research generally focuses on families of pollutants.


In general, there is no single device which provides complete water analysis.

Each search for pollutants is associated with an analysis involving a specific process.
