Understanding Drinking Water Contaminants

Types of Contaminants

Drinking water can contain various contaminants such as PFAS, pesticides, chlorine, chloramine, pharmaceuticals, hormones, bacteria, viruses, heavy metals (like lead and mercury), nitrates, fluoride, and microplastics. These substances, if present in high quantities, can have harmful effects on health.

Laboratory testing protocol

Different laboratory tests are carried out to detect these contaminants. Independent laboratories such as Envirotek, Eurofins, SGS and WQA play a crucial role in this assessment, providing objective measurement of water quality according to rigorous protocols.

Water Filtration Technologies

Gravity filtration systems

Gravity filtration systems, such as the Berkey, are among the most popular solutions for water treatment. They use activated carbon filters, ceramic filters or Black Berkey filters to purify the water. Thanks to brands like Monderma, it is possible to find filters adapted to different household needs.

Comparison and choice of filters

There are many models of water filters available, each with their own benefits. You can consult our comparative guide to selecting the right model for your home.

Water quality certifications

Differences between certifications and tests

  • Certified by NSF : Indicates that the product has been tested and certified to meet specific standards.
  • Tested to NSF standards : The product has been evaluated according to the criteria defined by the NSF, but has not officially received their certification.
  • Independent laboratory tests : Provide objective validation based on testing conditions defined by an independent laboratory.
  • Marketing claims : Not necessarily supported by objective tests or certifications.

NSF 42, 53, and NSF P231 certifications are important for evaluating filtration efficiency, covering the reduction of contaminants for the improvement of odor, taste, and potentially hazardous chemicals.
