Water analysis: detect contaminants and ensure regulatory compliance
Water testing is essential to ensure the quality and safety of water resources. Whether for drinking water, industrial water, or water discharged into the environment, rigorous monitoring is necessary to detect contaminants and ensure compliance with current regulations.
Analytical control to meet regulatory requirements
Regulations impose strict controls on water quality, whether it concerns drinking water (Directive 2020/2184/EU), wastewater (Directive 91/271/EEC), or industrial discharges. Our partner laboratories carry out comprehensive analyses to meet the requirements of health and environmental authorities, such as ANSES and DREAL.
Parameters analyzed and contaminants sought
Water analysis allows the evaluation of several physicochemical, microbiological and organic parameters, including:
- Chemical contaminants : heavy metals (lead, mercury, cadmium), nitrates, nitrites, phosphates, etc.
- Organic pollutants : polycyclic aromatic hydrocarbons (PAHs), pesticides, chlorinated solvents, VOCs, etc.
- Microbiological pathogens : Escherichia coli, legionella, fecal coliforms, sulfite-reducing anaerobes (spores), aerobic microorganisms at 22°C and 36°C, etc.
- Organoleptic quality : pH, turbidity, color, odor, etc.

Laboratory analysis methods
Our laboratories use cutting-edge techniques for reliable detection of pollutants:
- Gas chromatography (GC-MS, GC-FID) for the analysis of pesticides and hydrocarbons
- High-performance liquid chromatography (HPLC) for pharmaceutical residues and endocrine disruptors
- Mass spectrometry (ICP-MS, ICP-OES) for the determination of heavy metals
- PCR and microbiological culture for pathogen detection
Applications and sectors concerned
Water analysis is essential in many industrial and environmental sectors:
- Environmental monitoring : monitoring of groundwater, surface water and bathing water
- Food industry : verification of the quality of process water and discharges
- Water treatment : monitoring of treatment plants and industrial wastewater
- Construction and development : analysis of drilling water, leachate and runoff water
In addition, European veterinary regulations, including Regulation (EU) 2016/429 on Animal Health Law, impose strict infectious disease surveillance and biosecurity on farms and animal feed industries. YesWeLab's partner laboratories provide testing that meets international standards, ensuring reliable results and regulatory compliance .
