Geomeasure Group and it’s professional staff have many years experience in the fields of groundwater and geophysical investigations, groundwater supply, groundwater management and development and groundwater monitoring on small and large scale projects for both private and municipal/governmental clients.
Geophysical Investigations:
Our field staff have considerable experience in the use and interpretation of the following geophysical methods for groundwater exploration and borehole siting:
- Magnetics
- VLF Conductivity
- Electric Resistivity
- Electromagnetics
- Refraction Seismics
Regional Groundwater Studies:
- Aquifer assessment and classification
- Groundwater reserve determination
- Groundwater management for CMA’s
- Regional groundwater resource surveys and evaluation of groundwater development potential
- Groundwater chemistry studies
- Hydrocensensus studies
- Remote sensing and geological reconnaissance studies
- Groundwater sanitation protocols
- Desk top selection of candidate landfill or cemetery sites using negative mapping techniques
- Physical investigations and assessment of candidate landfill or cemetery sites
Groundwater Management:
- GIS – ArcView/ArcMap supported groundwater database development and management
- Wellfield monitoring – using remote information forwarding technology for real-time monitoring and remote control and management of abstraction systems and well-fields
- Aquifer and production borehole performance evaluation and optimising performance through real-time monitoring and remote control of pump systems.
- Aquifer modelling for development of management practices.
- Design and installation of monitoring networks
- Water quality monitoring – passive and/or real-time – compliance or investigative
Groundwater Development:
- Preparation of tender documents and administration of contracts
- Supervision of drilling and test pumping contracts
- Analysis of test pumping data
- Design of borehole and abstraction systems
- Design of primary reticulation systems
- Rehabilitation of existing water wells
- Liaison with communities
- Rural water supply
Projects
- Rural community water supply projects
- Carrying out detailed water resource assessments in rural communities, liaising with community leaders and developing committees to establish water needs and assisting with the planning of borehole and spring protection programs to develop sustainable domestic water supplies
- Mapping of existing boreholes and springs, taking field measurements of water quality and reporting on status of pump and reticulation systems
- Upgrading of existing spring intakes at wind turbines, extensions to reticulation systems and upgrading of storage reservoirs
- Detailed hydro census to accurately establish existing groundwater resources, and to identify areas in need of aid, siting of boreholes, borehole drilling supervision, and the supervision of a maintenance programme designed to repair and test all existing boreholes in a project area
- Sampling of boreholes so as to assess the groundwater quality within project regions
- Rainwater harvesting schemes implementation at schools and clinics to augment their current water supplies
- Industrial water resource development and management
- Regional water resource studies
- Golf course and estate water resource development and management
- Groundwater model development
- Groundwater Protocol Site Assessments
