Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

What evidence is required to demonstrate competence for this standard as a whole?

Competence in sampling and testing water quality requires evidence that water quality has been appropriately sampled and tested for a given site according to prescribed scientific procedures, standards and principles, monitoring schedules and industry best practice. The skills and knowledge required to sample and test for water quality must be transferable to a range of work environments and contexts. For example, this could include different locations, environments and monitoring schedules.

What specific knowledge is needed to achieve the performance criteria?

Knowledge and understanding are essential to apply this standard in the workplace, to transfer the skills to other contexts and to deal with unplanned events. The knowledge requirements for this unit are listed below:

Hydrological cycle.

Water monitoring schedules and guidelines.

Standards for water quality.

Sampling and testing methods.

Groundwater contamination evaluation.

Sources of groundwater contamination.

Groundwater salinity - mechanisms, occurrence and management.

Irrigation induced salinity, mechanisms and management.

What specific skills are needed to achieve the performance criteria?

To achieve the performance criteria, some complementary skills are required. These skills include the ability to:

Plan for sampling and testing.

Prepare equipment and resources.

Carry out sampling and testing.

Complete water sampling and testing activities.

Record and input data into various data entry systems.

What processes should be applied to this competency standard?

There are a number of processes that are learnt throughout work and life, which are required in all jobs. They are fundamental processes and generally transferable to other work functions. Some of these are covered by the key competencies, although others may be added. The questions below highlight how these processes are applied in this competency standard. Following each question a number in brackets indicates the level to which the key competency needs to be demonstrated where 0 = not required, 1 = perform the process, 2 = perform and administer the process and 3 = perform, administer and design the process.

1. How can communication of ideas and information (2) be applied?

Recording and reporting on sampling and testing activities.

2. How can information be collected, analysed and organised (3)?

Through completion of record sheets, taking of samples for external analysis and recording of observations.

3. How are activities planned and organised (3)?

Using appropriate equipment and in accordance with enterprise guidelines.

4. How can team work (3) be applied?

Co-operation in sampling and testing activities.

5. How can the use of mathematical ideas and techniques (2) be applied?

Through evaluation of sampling and testing results and reporting to supervisor.

6. How can problem-solving skills (2) be applied?

Assessing threats and changes to area being monitored.

7. How can the use of technology (2) be applied?

Use of field equipment and machinery.

Are there other competency standards that could be assessed with this one?

This competency standard could be assessed on its own or in combination with other competencies relevant to the job function.

For information about assessing this competency standard for consistent performance and where and how it may be assessed, refer to the Assessment Guidelines for this Training Package.

Range of Variables

The Range of Variables defines the different contexts, work environments and parameters governing the performance of this competency standard. The variables chosen in training and assessment will need to reflect local industry and regional contexts

What advance water quality parameters may be relevant to this competency standard?

Dissolved or suspended solids, nitrogenous products (TKN, TAN, NO2- ,NO3-), redox, ozone, soil pH, clay content of soil, contaminants (including pesticides, herbicides, heavy metals), biological oxygen demand, bacterial levels (E. coli and faecal coliforms), aquatic life, chlorophyll, phosphorus (total and orthophosphate), macro-invertebrates and macrophytes.

Which environmental parameters may be included?

Changes in native land-based and/or aquatic life around the site, sediment and debris levels, wastes and contaminants, toxic microalgae and presence of severe weather conditions.

What water quality and environmental parameters may be relevant to this standard?

Adjustment of probes or other settings for calibration, correlation and replacement of electronic parts, covers, probes.

How can erroneous readings be avoided?

By following monitoring schedule and standards, through regular readings (e.g., at the same time each month), by taking readings before irrigation cycles commence, by bailing out before taking the reading (especially where salinity levels are being assessed).

What types of samples may be included?

Water, weather station/meteorological data, sediments or soils, pests, predators or fouling organisms and vegetation (land and aquatic).

What samples for external analysis may be relevant?

Contaminants (such as heavy metals, pesticides, herbicides and other chemicals), proximate analysis of culture or other organisms, trace elements, mineral content of waters/soils and pathology.

What is meant by antecedent environmental conditions?

Previously relevant weather, rainfall, irrigation, tides or floods that could influence sample/test results.

Which OHSrequirements may be included?

Codes of Practice, regulations and/or guidance notes which may apply in a jurisdiction, andenterprise-specific OHS procedures, policies or standards

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
