Posted on 25 Jun 2020

As water quality monitoring forms part of monthly operational aspects related to compliance requirements associated with Water Use Licences (WUL), Environmental Monitoring Programmes (EMPr) and general duty of care (NEMA Section 28) it is vital to ensure correct sampling procedures according to specific water resources.

Numerous guidelines are present within the industry in order to obtain representative water quality composition, while the South African National Standards (SANS) extensively describes the precise sampling guidelines relative to the water resource category, preservation and handling. Several guidelines have been published by the South African Bureau of Standards (SABS) associated with the guidance and sampling methodology where the SANS 5667 standard is considered to serve as a minimum requirement to ensure adequate field monitoring and sampling for collection of representative water samples.
