Water Quality Sampling

Quality sampling in sewers and watercourses utilises specialised automatic sampling equipment. These samplers can be triggered to sample according to different criteria, the most practiced of which are:

Volume of flow; where the sampler is linked to a flow monitor, which activates the sampler. A typical application could be industrial or trade discharge. 'Flow proportional sampling'.

Depth; typically sampling the effluent discharged by a storm water overflow where the sampler is linked to a depth monitor which triggers the sampler once a depth threshold has been reached.

Time; simple time based samples where the sampler triggers itself at a pre determined time.

Samples usually need recovering from the sampler and delivering to a laboratory on a daily basis, depending on the triggering criteria. Samples are kept in a controlled chilled environment until delivered to the laboratory, so as to prevent degradation of the sample.

Water Quality Sampling is a very specialised and intensive activity in which AQS has a considerable depth of experience.

AQS can assist the client in: The planning of the sampling exercise and meeting the client for a Pre-installation site survey. After installation of the Automatic Samplers our crew would to visit the sampling site daily or be on 24 hour standby to retrieve samples.

Based on our experience in Water Quality Sampling, AQS can offer a full range of associated surveys, which include the following:

• Flow and load surveys
• UPM surveys data collection
• Continuous water quality monitoring
• Salinity monitoring
• DO, pH, and temperature monitoring

This list is not exhaustive and we will be happy to discuss any type of sampling that you may require.
