Microbiological analysis of well water or drilling after desinfection

When should you retest the microbiological quality of your well water ?

When the water is intended for human consumption, for domestic purposes or if the water is in contact with food, it is advisable to carry out a regular potability analysis.

Water of poor microbiological quality can be responsible for digestive disorders but also for infections of the skin and mucous membranes, especially in the case of lesions or particular sensitivities. Microbiological contamination can come from a pile of manure, from defective non-collective sanitation (septic tank), etc.

Following a non-compliant microbiological result, it is necessary to carry out a disinfection of your well and to control the microbiological quality of your water again.

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.
