GROUNDWATER SAMPLING:
Groundwater sampling can be undertaken for a variety of reasons. For example, the information derived from groundwater sampling, and the ensuing analyses and interpretations of the hydrochemical and isotopic results could significantly assist in the:
• identification of the aquifers intercepted by water bores
• determination of leakage and hydraulic connection between aquifers
• assessment of groundwater movement and flow patterns
• understanding of recharge-discharge mechanisms
• determination of the nature of surface water and groundwater interconnectivity
• identification of the magnitude, sources and transport of salt, nutrients, pesticides and other contaminants
• delineation of natural discharge and environmental use (such as base-flow)
• identification and evaluation of groundwater-dependent ecosystems
• evaluation of baseline groundwater quality and the relevant beneficial uses of the groundwater resource
• understanding of the evolution of the groundwater chemistry and flow patterns, and possible causes for groundwater quality changes
• assessment of the impact of land use changes, irrigation and groundwater extraction on the regional groundwater quantity and quality
• developing groundwater as an effective sampling medium for mineral exploration
• assisting in the characterisation of geothermal resources and technical issues associated with their development, and
• assisting with site selection and monitoring of geologically stored CO2.
SCOPE OF THIS GUIDE:
This guide has been developed to provide sufficient information to plan and carry out field groundwater sampling of a high standard, ensuring that only representative, high integrity samples are collected and submitted for laboratory analysis. The main aims of the guide are to:
• provide a comprehensive practical overview covering the basic elements of effective groundwater sampling
• provide simple and efficient methods for monitoring groundwater systems, and
• outline procedures for sampling from the bore site to delivery to the laboratory.
