The water quality testing, carried out at the organisation’s SANAS-accredited laboratory by the Scientific Service Unit, is divided into four categories, namely physical, chemical, microbiological and operational as per SANS 241: 2015 requirements.
River monitoring is conducted through the assessment of using biomonitoring and bioaccumulation. Lepelle Northern Water appoint the competent service provider to conduct the biomonitoring to the river during dry and wet season which Lepelle Northern Water abstract water from such as Olifants, Spekboom, Steelpoort river and others. Biomonitoring involves the use of organisms to assess environmental contamination, such as of surrounding air or water by observing or measuring the effects the environment has on its resident organisms, pollution may be suspected or inferred. The reports are presented at the regional meetings for implementation and used as a as a baseline for the bio-monitoring survey and will be utilised as stipulated in the water license.
Accreditation: ISO 17025
In 2018/19 the organisation’s Central laboratory underwent surveillance audits by the accreditation body, South African National Accreditation System (SANAS) and accreditation was re-instated in the chemistry laboratory and 4 new additional methods were added on the accreditation schedule.
The matrix tested for at the laboratories includes potable, borehole, river and effluent water for microbiological, chemical and physical parameters. Quality management systems is currently improved to comply with the new version of ISO 17025: 2017.
