Geologic Interpretation

Geologic mapping, well location selection and logging, and subsoil investigations are key to delineating your mineral or water resources. Geolex can perform mineral evaluations for mining ventures or conservation easement properties, well siting for residential or industrial water supplies, and structure contour mapping for subsurface drilling programs.

  • Geologic mapping and soil classification
  • Mineral resource assessment/oil and gas
  • Aquifer characterization

Applied Geomorphology

Proper resource management of your waterways and upstream riparian corridors allows for preservation and/or enhancement of adjacent lands, water quality, and habitat value. And healthy streams are the result of effective monitoring, channel maintenance, and land-use planning.

  • Monitoring and mitigation of erosion and non-point source pollution (from mining, logging, agriculture, grazing, construction)
  • Floodplain delineation, riparian inventories, resource protection
  • Stream mapping: cross-sections, longitudinal surveys, discharge determinations; classification, channel and riparian habitat restoration
  • 310/404 permitting assistance and technical review
  • Surface flow modeling, TMDL monitoring

Wetlands Characterization

Natural and artificial wetlands are paramount to maintaining water quality and increased biodiversity on your property. Preservation of existing wetlands, or mitigation of disturbed areas from construction, road building, or agricultural/silvicultural practices is required for legal compliance and maximizing your land value.

  • Delineation, mapping, and classification of wetlands and deep-water aquatic habitats (riverine, lacustrine, and palustrine)
  • Planning hydrology for wetland preservation, enhancement, or replacement during construction
  • Pond construction for water quality, fisheries, or aesthetic enhancement
