Aim of Analytical services
Analytical Services is responsible for water quality analysis,
supporting the water resource management and water supply functions of
the Department. The water resources quality information team provides
data and information for a comprehensive set of water quality
constituents, i.e. major salts, nutrients, trace metals, biological entities
and organic contaminants. The laboratories house several
specialist groups with expertise in sample analysis, computer
technology and laboratory equipment. These groups work together to provide
comprehensive support to water resource management.
Scope of analysis
The following methods form part of the scope of test work on potable water,
groundwater and surface water samples, conducted at Resource Quality Information Services.
SANAS has withdrawn all accreditation, effective from 25 September 2018,
because of laboratory inability to meet accreditation requirements due to financial constraint.
