WATER SHARING PLAN FOR THE STUARTS POINT GROUNDWATER SOURCE 2003 - SCHEDULE 1

SCHEDULE 1 – Dictionary

The following definitions apply to this Plan in addition to the definitions set out in the Act:
"abandoned" refers to a water supply work (bore) that is no longer being used.
"available water" in relation to a water management area or water source, is the water that is available in that area or water source in accordance with an available water determination that is in force in respect of that area or water source.
"available water determination" is a written Order by the Minister as to the availability of water for the various categories of access licence in relation to a specified water management area or water source.

Note: An available water determination gives rise to a water allocation that is credited to a water allocation account for each licensed holder.
"basement rock" is a general term for solid rock that lies beneath soil, loose sediments, or other unconsolidated material.
"component" see share component.
"contamination sources", relates to human activities that have resulted in the presence of a substance in the groundwater source at a concentration above that at which the substance is normally present, and at a level that presents a risk of harm to human health or reduces the beneficial use of a groundwater source.
Note: Contamination sources can arise from a range of industrial and other land based activities. The impact of some activities will be temporary, while others pose a risk over a much longer timeframe. In some instances, particularly when the land use has involved hazardous substances, the source may be threatening to humans, or may affect the current or future beneficial uses of the groundwater source. Determining in any particular case whether or not contamination presents a significant risk of harm can be complex and difficult. It involves considerations such as the type, nature, quantity and concentration of contaminants, how they manifest themselves and the nature of their impact in the particular groundwater source. It also involves broader questions such as the current use of the groundwater source, who might be exposed to the contamination under that use, and whether they would be exposed.
"drawdown" refers to a lowering of the piezometric surface. Natural drawdown may occur due to seasonal climatic changes. Groundwater pumping may also result in seasonal and long-term drawdown.
"extraction limit" is the amount, on average, of the long-term average annual recharge and storage that can be extracted each water accounting year.
"groundwater" is water that occurs beneath the ground surface in the saturated zone.
"groundwater dependent ecosystems" are ecosystems which have their species composition and natural ecological processes to some extent determined by groundwater.
"monitoring bore" refers to a bore constructed for the purpose of measuring water levels and/or taking samples for water quality analysis.
"piezometric surface" is a surface that represents the level to which water will rise in cased bores.
"Pleistocene age sand formations" are siliceous sand dunes likely to be formed by wave action and aeolian reworking on a rapidly prograding shore with a large sand supply, periodically cut during storms, and subsequently forming parallel ridges up to 40 metres depth.
"recharge" is the addition of water, usually by infiltration, to an aquifer.
"share component" is the share component of an access licence.
"watertable" is the upper surface of an unconfined aquifer.
