Water analyses laboratory
![Analyse-eau](/sites/default/files/styles/produit/public/2023-06/Bandeau%20tubes%20et%20gouttes_0.png.webp?itok=ux5nd92x)
Your laboratory is a water analysis service provider, a local authority public laboratory or an Urban Wastewater Treatment Plant (WWTP) laboratory.
Your laboratory measures physico-chemical or microbiological parameters in water.
AGLAE provides you with a whole range of interlaboratory comparisons on different types of water.
![laboratoire analyse eau](/sites/default/files/styles/produit/public/2023-11/Labo-analyse-eau.jpg.webp?itok=zrPMocqs)
Water analysis framework
- Water analyses are part of the monitoring of water intended for human consumption ("drinking water"), surface water (lakes and rivers), groundwater or sea water.
- Tap water is monitored for microbiological, physico-chemical and radiological parameters to ensure that it complies with regulatory quality requirements and poses no risk to consumer health.
- In the case of a wastewater treatment plant, inlet (raw water) and outlet (treated water) analyses help to monitor discharges and the operation of the facilities. If the performance of the waste water treatment plants is not sufficient to eliminate all the pollutants, some of these substances are likely to be discharged (see water pollution).
It should be noted that depending on the type of water, water must comply with various quality criteria: physico-chemical parameters, organoleptic parameters (taste and odour for drinking water), microbiological parameters, parameters relating to undesirable substances and toxic substances.
![Quality-control-laboratory](/sites/default/files/styles/produit/public/2023-08/Controle-qualite-laboratoire.jpg.webp?itok=nCjysKDt)
Your expectations in terms of Quality Control
As part of your accreditation to ISO 17025 and/or approval, your laboratory must meet the requirements of :
- accreditation related to water sampling, physico-chemical and microbiological testing
- approvals issued by the Ministry of Health to carry out sampling and analysis for water health control purposes
- approvals issued by the Ministry for the Environment to carry out analyses in the field of water and aquatic environments
You must ensure the validity of your results and monitor your performance by comparing it with the results of other laboratories.
As an urban wastewater treatment plant, you check your performance as part of your self-monitoring system.
