Perform blue green algae sampling

Assessment tool

Version 1.0
Issue Date: April 2024


This unit supports the attainment of skills and knowledge required for field and operational staff with specific responsibility for collecting blue green algae samples for identification, enumeration and toxicity testing.

This unit of competency describes the outcomes required to collect and prepare water and wastewater samples for blue green algae identification, enumeration and toxicity testing according to standard operating procedures.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Prerequisites

Not applicable.

Employability Skills

This unit of competency contains employability skills.



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.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, the range statement and the Assessment Guidelines for the Training Package.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The candidate should demonstrate the ability to perform blue green algae sampling, including:

planning and preparing for sampling tasks

collecting samples according to sampling plan

maintaining integrity of samples

recording required information.

Context of and specific resources for assessment

Access to the workplace and resources including:

documentation that should normally be available in a water industry organisation

relevant codes, standards and government regulations.

Where applicable, physical resources should include equipment modified for people with disabilities.

Access must be provided to appropriate learning and assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the language and literacy capacity of the candidate and the work being performed.

Validity and sufficiency of evidence requires that:

competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace

where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice

a decision of competence should only be made when the assessor has complete confidence in the person's competence over time and in various contexts

all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence

where assessment is for the purpose of recognition (RCC/RPL), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time

assessment can be through simulated project-based activity and must include evidence relating to each of the elements in this unit.

In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in a manner appropriate to the skill levels of the operator and cultural issues that may affect responses to the questions, and will reflect the requirements of the competency and the work being performed.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

This describes the essential skills and knowledge and their level, required for this unit.

Required skills:

use personal protective equipment.

Required knowledge:

types and purposes of blue green algae samples

procedures and techniques for blue green algae sampling

sample preparation, including:

prevention of contamination

volume of sample

appropriate containers

preservation

location selection

location maintenance

equipment

transportation

documentation procedures for samples

legislative and organisational policies, procedures and standards

communication systems

work planning processes

hazards associated with collection of blue green algae samples.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts.

Samples may include grab, integrated or concentrated samples for:

identification

enumeration

toxicity testing.

Legislative and organisational requirements may include:

Australian standards, for example AS/NZS 5667 Water quality - sampling

state Environment Protection Authority sampling guidelines

relevant federal and state or territory legislation and regulations

codes of practice, associated standards and guidance material

documented organisational policies, manuals and induction programs

relevant community planning and development agreements, such as land care agreements.

Sampling equipment may include:

buckets or wide-mouthed containers

depth samplers

sample dippers

hose pipe samplers

plankton nets

laboratory supplied sample containers

weighted sample bottles.

Sample preservationmethods may include:

refrigeration

chemical addition, such as Lugol's iodine solution.

Planning sampling work activities may include:

interpreting instructions and directions

planning timelines

interacting and communicating with team members and individuals

considering customer service requirements.

Sampling locations may include:

water storages

rivers

wastewater lagoons.

Records may include:

sample records, field detail sheets or chain of custody forms, including information such as:

time sample was taken

details of person collecting sample

sample point

volume of sample

data gathered at time of collection

preservation techniques.

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.
