Chapter 3 - Freshwater The objective and policies are designed to provide for the sustainable management of the groundwater resource in a way which will safeguard surface water ecosystems and provide for the wellbeing of present and future generations. Wide fluctuation in the levels and flows of water in aquifers occur naturally. These fluctuations relate to seasonal and annual variations of river flows and rainfall. The groundwater systems have evolved to accommodate the natural range of fluctuations in flows and levels of water. The use of water should not alter aquifer flows and levels in a way which is irreversible so that the groundwater levels are unable to recover. Refer to Chapter 14 (Discharges of Waste to Land) for more detailed policies relating to the effects of land use activities on water quality. 3.3.3 Methods of Implementation Rules Council will control the abstraction of groundwater, beyond a determined level, with safeguards to protect freshwater flows and levels. Investigation Promote the investigation of potentially contaminated sites and promote remedial works where problems are identified. Investigate the operation of septic tanks in areas where contamination of groundwater is identified and require remedial works to be carried out. Education Undertake an education programme in the use and maintenance of septic tank systems to minimise the effects of sewage effluent on land and water ecosystems. Undertake an education programme addressing the potential of land uses to contaminate infiltration waters recharging aquifers. Research Support research into the cumulative effects of land-based activities on groundwater quality. Section 14 of the Act restricts the taking of water, therefore, rules are necessary to clarify the circumstances under which groundwater may be extracted. The investigative and research methods are directed at enhancing existing water quality. Further methods relating to land use effects on groundwater quality are included in Chapter 14 (Discharges of Waste to Land). 3.4 Anticipated Environmental Results Implementation of the policies and methods relating to water will result in: Protection of all wetland, lake and river ecosystems while enabling the community to make use of the fresh surface water resource; 3 - 9
