Water quality

Water quality sampling and analysis

Analyses according to specifications

MANUMESURE can test the quality of waste water, rain water and underground water on any site.

 

Various parameters can be measured according to the customer's specifications: pH, temperature, chemical oxygen demand, pesticides, BOD5, suspended solids, PCBs, total hydrocarbons, heavy metals, nitrates, etc.

Waste water and rain water quality tests

Sampling and methodology
Sampling is performed in compliance with the ISO 5667 standards on water sampling and the FD T 90-523-2 document: "Water Quality - Sampling guide for monitoring water quality in the environment - Waste water sampling".

Two types of sampling are possible: 24-hour survey or point sampling.

24-hour survey
Sampling using a flow-controlled or time-controlled sampling system with continuous measurement of pH and temperature. When sampling has finished, an average sample representative of the day when measurement took place is established and analysed.
This sampling method allows assessment of the average daily values for waste water.

Point sampling
This method, used to assess the instantaneous value for an effluent, is used for effluent which remains homogeneous over time or for effluent linked o a specific event: rain, accidental pollution, etc.

 

Types of analyses
Various parameters can be measured according to the customer's specifications: pH, temperature, chemical oxygen demand, pesticides, BOD5, suspended solids, PCBs, total hydrocarbons, heavy metals, nitrates, etc.

Monitoring of underground water quality

This sampling and analysis has two main aims:

  • Checking that water quality has not been altered by agricultural, industrial or other activities.
  • Detecting any pollution or monitoring the evolution of a pollution event already detected.

Methodology
These measurements are performed in compliance with AFNOR technical document FD X31-615 "Soil quality - Methods for detecting and characterizing pollution - Sampling of underground water in a bore-hole".
Our technical resources enable us to take samples at depths of up to 70 metres.

 

Types of analyses
Various parameters can be measured according to the customer's specifications: pH, temperature, chemical oxygen demand, pesticides, BOD5, suspended solids, PCBs, total hydrocarbons, heavy metals, nitrates, etc.

Measurement report
At the end of the measurement campaign, a report is drawn up presenting the methodology, a site description, the analysis results and a comparison with the regulated values.
