Groundwater modeling is a powerful but sometimes misused tool. Converse's groundwater modeling specialists take information from complex, heterogeneous earth systems, distill this complex information into a set of simplified numerical inputs, perform calculations, and use computer software or other means to produce numerical output. In order to maximize the potential benefit of a groundwater modeling activity, the modeling must be done by experienced personnel who understand the mathematical basis of models, the intended use of the models, and the reliability and precision of model output.

Numerical modeling of aquifer performance may be used to assess the long-term, safe yield of a well or wellfield and potential impacts upon nearby water features such as streams, springs and/or wetlands. Numerical modeling of aquifer performance may also be used to assess the effectiveness of pollution remedial systems. Sewage facilities planning may benefit from numerical assessment of the behavior of sewage constituents (such as nitrate-nitrogen) in groundwater.

Geographic Information System (GIS) is an innovative technology that couples mapping and database computer applications. As more groundwater and other natural resource data become available in electronic format, GIS is emerging as an extremely powerful tool for water resource utilization and management, especially for large geographic areas, groundwater basins, and as a planning tool for land use management. Recognizing the importance of this new technology, Converse is committed to maintaining the equipment, software, and skilled personnel to take advantage of ongoing improvements in GIS technology.
