|Contexte de l'analyse||I want to verify that my installation (piping, taps) preserves the quality of the water.I want to measure the efficiency of my water treatment equipment (softener, filters, coals, etc.) and make sure that they do not 'bring no bacterial contamination.|
|Règlementation||Order of January 11, 2007 relating to the program of sampling and analysis of sanitary control for water supplied by a distribution networkOrder of January 11, 2007 relating to the limits and quality references of raw water and water intended for human consumptionInovalys performs the tap water analysis in accordance with these regulatory texts: D1 type analysis.See "Downloads" section below.|
|Liste des analyses réalisées||Appearance, color, odor, pH, ammoniacal nitrogen (NH4), nitrates (NO3, Aluminum, iron, conductivity, turbidity, anaerobic sulphite-reducing bacteria (spores), coliform bacteria, Escherichia coli, intestinal enterococci (= fecal streptococci), micro - aerobic organisms revivable at 22 ° C and 36 ° C|
Description of the analyzes carried out by the laboratory
-Micro-organisms revivable at 22 ° C and 36 ° C :
Their presence is normal but a high number is undesirable
-Coliform bacteria and anaerobic sulfite-reducing bacteria :
Witnesses of contamination by runoff and therefore poor protection of a well; no direct health consequences
-Escherichia coli and intestinal enterococci :
These germs are of strictly faecal origin and testify to pollution by sewage, liquid manure, animals ... They can be accompanied by pathogenic germs causing gastric disorders or sometimes more serious diseases.If present, it is advisable to disinfect the well.
The presence of enterococci alone, without E.coli, suggests an old, non-active contamination.
-Appearance, color, odor : A change is abnormal
-pH : Express the acidity or alkalinity of water. A very low pH (acid) induces risks of corrosion of metallic elements.
-Conductivity : Evaluation of the overall mineralization of water; conductivity increases with mineralization
-Turbidity : Assessment of water disorder; often linked to the presence of iron or poor filtration by the soil (poor protection in the event of various types of pollution)
-Ammoniacal nitrogen (NH4) : A high content can come from fertilizers or sewage, liquid manure, liquid manure ...
-Nitrates : come from fertilizers or the evolution of animal or human excrement. Between 50 and 100 mg / l, the risk exists especially for pregnant women and infants (methemoglobinemia).
-Iron : Too much content causes color and taste as well as fouling problems (linen, dishes, pipes ...) or corrosion.
-Aluminium : Its presence in tap water can be linked to the use of aluminum salts during a stage of water treatment.
