Private landholders, industry and regulators alike, are in most cases the individuals who understand the amount of groundwater an aquifer or well can produce sustainably. The most reliable method of investigation, is by pumping a well and measuring the response; this investigation is known as a pump or aquifer test. Aquifer testing provides vital information concerning well performance, aquifer characteristics and the sustainable pumping rate that can be achieved from the aquifer that a bore is installed into. Epic Environmental, provide services in the design and field supervision of aquifer tests, as well as the analysis of the test data.
Testing services include:
- Multi-step and constant rate discharge tests;
- Slug tests (falling/rising head tests) and
- Drill String Tests.
Under the Queensland legislation, it is made clear that a resource tenure holder must undertake a baseline assessment on any bores that could potentially be impacted by their activities. The objective of the assessment is to gain information relating to water level and quality (geochemistry), bore construction details, and the type of infrastructure used to abstract water from the bore. Information gained from the assessments, establish the benchmark or “baseline” conditions prior to the bore experiencing any impacts from the resource tenure holder; exercising their rights to access water. Resource tenure holders are essential to engage an independent third party to undertake baseline assessments; third parties must be considered suitably qualified under Queensland legislation with sufficient experience in monitoring groundwater and practical knowledge across water bore construction and pumping infrastructure.
Our team have been involved in numerous baseline study programs across the mining and CSG sectors, displaying our broad level of experience across groundwater monitoring and assessment. At Epic, we are well – respected in the industry and known to government regulators as responsible for administering the necessary legislation; our team provide knowledgeable advice to contribute to all projects’ success.
The remoteness of field monitoring locations makes field water monitoring and data gathering an expensive exercise; with personnel, site vehicles, field equipment and travel, all adding to the costs. Site monitoring at infrequent intervals (weekly, monthly), can also result in small data-sets with limited use in environmental site assessments and decision-making processes. Our team at Epic Environmental, are conversant in the provision of water telemetry systems to reduce ongoing costs associated with routine monitoring of groundwater and surface water. Applications across both greenfield and brownfield sites, and telemetry networks can be designed for almost any location across Australia; with mobile network coverage, providing up-to-the-minute data acquisition. As part of our service, Epic also provides data hosting for telemetered sites, ensuring that field data is maintained in a secure location and is easily accessed at all times.
