Consultancy Services

Solving challenges in groundwater exploration, development and production. We can support your project through initial planning, gaining consents, understanding the size of the resource, and managing diverse environmental issues. Our services include:

 

Resource Assessment

Insight into your groundwater resource through hydrogeology, geophysics, geochemistry and water dating expertise. Our specialists can:

  • Identify the size and boundaries of aquifers
  • Clarify flow rates and directions
  • Advise on best water take
  • Identify contaminant flow paths
  • Assess and map sediments, fracture zone locations, porosity and geological structures
  • Advise on well siting
  • Report on aquifer analyses for resource assessment
  • Assess security of supply and water quality
  • Advise on technique selection, survey design and water quality monitoring
  • Develop conceptual and numerical models

Whether you need to plan or progress use of new groundwater resources, site bores, increase the draw from an existing well, or address contamination and environmental issues, we can help.

Water sampling and Analysis

Chemical analysis for assessing the origin, quality and potential use of groundwater resources. We can:

  • Assess and compare water quality to relevant guidelines and standards
  • Report on environmental issues
  • Clarify seasonal variation in water composition and identify long term trends
  • Assess effects of land use on water quality
  • Indicate nitrogen and pollutant sources
  • Predict future water quality
  • Undertake ongoing water monitoring 

 

Dating and Tracing Water

Assessing aquifer sustainability and vulnerability to support early detection of deteriorating water quality.

  • Identify recharge areas, flow paths, mixing and aquifer structure
  • Identify and compare effects of land-use on water quality
  • Validate groundwater flow models
  • Determine the security of your groundwater supply, as per the Drinking Water Standards for New Zealand: 2005

Environmental Studies

Identifying environmental issues such as land-use change, water balance, contaminant effects and seawater intrusion.Applications include:

  • Contaminated site studies
  • Water quality monitoring
  • Geological environment setting descriptions
  • Water and soil sampling and analysis
  • Hydrological and sedimentological modelling
  • Groundwater flow and contaminant transport modelling
  • Independent scientific input for resource consents.

Maps, Models and Databases

Integrated and customised groundwater maps, models and other data for your specific needs.  Includes:

  • 2D and 3D modelling- tailored to suit your needs, including steady-state and transient models of groundwater systems, and coupled groundwater-surface water systems.
  • Geographic Information Systems(GIS) - customised and integrated resource data, such as geology, chemistry, geophysics, and potentiometric surfaces.
  • GNS Geothermal and Groundwater Database (GGW)– New Zealand data sets
  • Secure data storage – where you can access it
  • Customised databases to suit your needs
  • a range of software to ensure compatibility with your existing systems including FEFLOW, MODFLOW, MIKE-11, MIKE-SHE, and WMS.   

Laboratory Facilities

  • Stable Isotope Laboratory (D/H, 13C, 18O, 34S, 15N): for geology, archaeology, environment, food adulteration and agriculture.
