PURPOSE OF THE UNIT STANDARD 
The qualifying learner achieving this unit standard in combination with context expertise standard(s) will be able to take samples for process monitoring and investigative purposes and interpret data to accurately monitor water quality. The unit standard will expand the skills base of the qualifying learner and make the person more effective in his/her tasks and more employable which will open up job opportunities in related fields. This competence will enable the learner to do water quality sampling in various water environments. This will ensure that the water resources are accurately monitored in terms of water quality.

    This unit standard has been replaced by unit standard 255978, which is "Take non-routine investigative samples for monitoring process in water and wastewater works", Level 4, 8 credits.

    Integrated assessment:

    When conducting assessments, assessors must ensure that they are familiar with the full text of the unit standards being assessed. Assessors must ensure that the assessment covers the specific outcomes, critical cross-field outcomes and essential embedded knowledge by developing assessment activities and tools, which are appropriate to the contexts in which the learners are working. These activities and tools may include self-assessment, peer assessment, formative and summative assessment. It may be more effective and efficient to assess a number of unit standards together in an integrated way, thus reducing the overall number of assessments and ensuring that commonalities that exist between a number of unit standards are captured in a way that makes sense for assessment.

    Assessment option:

    Learners could be assessed using the following methods:
    Oral or written questions
    Observation
    Product sample reports/log book

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
