The evaluation of hydrogeological systems is linked to site-specific monitoring programs and/or the use of multidimensional numerical flow and transport models. Depending on the issue involved, the models can be hydraulic, hydrochemical, or thermodynamic, while corresponding model couplings are generally possible.

Regional surface and subsurface information provides a comprehensive tool for a 3-D analysis of rock bodies and reservoirs. 

• Well construction
• Well design
• Supervision of drilling
• Supervision of logging
• Supervision of testing
• Hydrochemical analysis
• Reporting and documentation

​ghc-Forestier has designed more than 250 different wells.

Contaminated sites characterize long-term deposits at former industry locations or industrially used areas where environmentally dangerous substances were handled and which can present dangers for the environment or human health. ghc-Forestier contributes to the systematic processing of contaminated waste sites and develops directive approaches and concepts for danger prevention.

Your project is in trouble and you need urgent measures:

• Analysis of geologic and hydrogeologic background
• Analysis of tender documents
• Analysis of technical proposal
• Analysis of general and on-site workflow
• Analysis of on-site working documents
• Analysis of potential legal weaknesses

An effective and sustainable groundwater management demands inter-disciplinary approaches and specified solution strategies. ghc-Forestier provides exploration services and corresponding production and protection concepts as well as customer specific system solutions in the framework of water-related economical tasks.

• Delineation & management of groundwater protection areas
• Vulnerability assessment
• Groundwater exploration services
• Groundwater balance estimation
• Decision Support System (DSS) development for management issues
• Optimised groundwater extraction/abstraction design

"Exploration" activities, in which ghc-Forestier has been involved, include development of groundwater supplies from the shallow subsurface down to a depth of over 2,500 meters. ghc-Forestier can handle any or all of your licensing application requirements, including:

• Feasibility analysis of alternate water supplies
• Test well drilling supervision
• Geohydraulic tests (aquifer test / well performance test)
• Groundwater sampling and hydrochemical analysis
• Long-term yield determinations and aquifer impact analyses
• On-going groundwater monitoring and reporting as per license conditions

The utilization of multi-dimensional numerical groundwater models in combination with representatively collected field data provides the customers with robust system analyses as well as reliable planning and prognosis instruments in all areas of inquiry. ghc-Forestier conceives and executes case-specific measurement campaigns.

• Geohydraulic characterization of porous, fractured, and  karstic aquifers
• Case studies of regional groundwater flow and solute transport processes
• Numerical 2-D/3-D groundwater flow and solute transport modeling
• Density-coupled transport modeling (seawater intrusion/brine uptake)

Data management combines management issues and technical solutions for storing, accessing, and analyzing geo-spatial information. An efficient data management focuses on the interface between geo-scientific data and specified business processes and will help to minimize the effort for the data processing and analysis.

• Data management and transfer (database systems, automatic data transmission, web-based data visualization)
• Geographic & (hydro-)geological database development, and maintenance
• Mapping and Geographical Information Systems (GIS)
• Spatial data analysis, visualization, and presentation
