Assessors must be satisfied that the candidate can competently and consistently apply the skills covered in this unit of competency in new and different situations and contexts Critical aspects of assessment and evidence include

planning and safely conducting surveysinspections of a range of stormwater system components that meet user needs

accessing and using existing environmental data sets

providing detailed descriptions of catchment characteristics existing conditions management values environmental issues and possible causes

completing all documentation in the required format and timeframe

working safely

Context of and specific resources for assessment

This unit of competency is to be assessed in the workplace or simulated workplace environment

Assessment should emphasise a workplace context and procedures found in the candidates workplace

This unit of competency may be assessed with

MSSA Collect spatial and discrete environmental data

MSS024005A Collect spatial and discrete environmental data

MSSA Perform sampling and testing of water

MSS024006A Perform sampling and testing of water

MSSA Collect and evaluate meteorological data

MSS024007A Collect and evaluate meteorological data.

The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team

Resources may include

access to natural and constructed drainage systems and combinations of these

sampling equipment field instruments and materials

enterprise procedures test methods and equipment manuals

Method of assessment

The following assessment methods are suggested

review of data results and records prepared by the candidate

feedback from peers and supervisors that the candidate consistently follows enterprise procedures samplingmeasurement procedures and works safely

oralwritten questioning associated with inspectionsurvey of stormwater systems samplingmeasurement equipment and procedures and stormwater assessment techniques

observation of the candidate collecting samples and conducting field tests

In all cases practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly

Where applicable reasonable adjustment must be made to work environments and training situations to accommodate ethnicity age gender demographics and disability

The language literacy and numeracy demands of assessment should not be greater than those required to undertake the unit of competency in a worklike environment

Environmental issues and possible causes

Environmental issues and possible causes may include:

poor water quality in waterways (wet/dry conditions) due to excess fertiliser application, washing of cars in streets, sewer overflows, domestic animal droppings and atmospheric deposition

inappropriate stream flow regime (flooding, base flows) due to increased run-off from impervious areas and insufficient stormwater reuse

degraded aquatic habitats due to increased sediment deposition, removal of riparian vegetation

barriers to aquatic fauna migration weirs

degraded riparian vegetation due to introduction of exotic species and vegetation removal

channel erosion and sedimentation due to increased flood flows following urbanisation and vegetation removal

litter in watercourses due to insufficient number/emptying of rubbish bins and commercial waste

weed growth in urban bushland due to stormwater nutrients, weeds from residential gardens, and removal of canopy vegetation

degradation of ecologically sensitive water bodies

health risks associated with recreational use of polluted waters

low visual amenity and landscape value due to litter along watercourses and concrete lined channels

Occupational health and safety (OHS) and environmental management requirements

OHS and environmental management requirements:

all operations must comply with enterprise OHS and environmental management requirements, which may be imposed through state/territory or federal legislation - these requirements must not be compromised at any time

all operations assume the potentially hazardous nature of samples and require standard precautions to be applied

where relevant, users should access and apply current industry understanding of infection control issued by the National Health and Medical Research Council (NHMRC) and State and Territory Departments of Health
