Hydrogeology and Water Resource Management

Groundwater is a precious resource that requires appropriate management to ensure its long-term sustainable use and protection. Many industrial and landfill sites have groundwater contamination caused by historical land use. Hydrogeological assessments examine the presence of such contamination and whether the concentrations of chemicals identified in groundwater are significant. These assessments will identify risks to the groundwater itself and associated water features such as streams, rivers, wetlands and groundwater drinking supplies. Thus, effective Hydrogeology and Water Resource Management can be done.
If significant contamination is identified, remediation (clean up) of the groundwater may be required to ensure protection of the environment. ENVIROZONE has the skills to ensure a cost-effective remediation scheme or Hydrogeology and Water Resource Management is proposed and carried out, often letting the site be developed as the clean-up works progress.
The Hydrogeology and Water Resource Management Includes

• Desktop review of geology and hydrogeology from both local and regional context
• Water sourcing and availability studies and focused field investigations (such pump test, water quality sampling and analysis) to determine aquifer characteristics and sustainable yield.
• Modelling studies using suitable software such as VIS-MODFLOW to assess short, medium and long term impacts on groundwater quality and availability.
• Recommend location for installation of water wells and liaise with regulatory authorities for well permits and approvals.
• Onsite supervision and support during drilling activities such as mud logging, pump test, water quality analysis and yield calculations.
• Identification of recharge zones, development of aquifer management strategies and master plans for the protection and management of groundwater resources.
