Bacteria in your water?
We'll take care of it.
The presence of bacteria in water is not always visible, nor can it be detected by taste or smell. An analysis allows you to check the bacteriological quality of your water and identify appropriate solutions.
With over 70 years of expertise, Culligan supports Quebec households in analyzing and protecting their drinking water, with complete transparency.
Why might there be bacteria in the water?
The presence of bacteria in water is not always linked to a visible problem or a bad smell. Even clear, odorless water can contain microorganisms that affect its microbiological quality. These bacteria can come from natural sources, the environment, or the infrastructure that transports water to your home.
The consequences of having bacteria in water

Non-potable water
The presence of bacteria such as E. coli or coliforms indicates that the water does not meet recommended drinking water standards. Even if the water is clear, odorless, and appears normal to the eye, it may contain invisible microorganisms that make it unsafe to drink.
Water that has been declared unsafe for consumption should not be used for drinking, cooking, or food preparation without proper treatment. This situation is common in homes supplied by wells, particularly after heavy rains, infiltration, or problems with well protection.

Gastrointestinal problems
Ingesting water contaminated with bacteria can cause gastrointestinal disorders, such as stomach ache, abdominal cramps, diarrhea, or nausea. These symptoms may appear quickly after consumption or occur repeatedly when exposure persists.
Children, the elderly, and people with weaker immune systems are generally at greater risk of experiencing these effects. Even mild symptoms can indicate a water quality issue that requires immediate attention.

Limited water use
When bacterial contamination is detected, water use becomes severely restricted. Water must often be boiled before consumption and avoided for certain uses such as brushing teeth or preparing meals.
These constraints quickly complicate daily life and create uncertainty about the safety of the water used in the home. Without a reliable disinfection solution, the problem may persist and require temporary measures in the long term.

Property inspection
A water test that fails due to the presence of bacteria is often a deal breaker during a pre-purchase inspection, particularly for properties served by a private well.
In several cases, corrective measures are required before the transaction can be completed in order to make the water drinkable. This can lead to delays, unexpected costs, or downward negotiations until the water quality is restored and compliant.
