Groundwater
Balance Hydrologics' groundwater practice emphasizes development of groundwater supply, watershed management, and wetland dynamics. The company has built on a solid base of professionals in hydrogeology, hydrology, geomorphology and engineering with particular expertise in:
  • Groundwater basin management and 'safe-yield' supply
  • Groundwater recharge management, including aquifer storage and recovery
  • Surface and groundwater hydrology, and their interaction
  • Managing groundwater near sensitive habitat areas
  • Aquifer simulation and monitoring
  • Hydrogeologic support for water-well drilling, testing, and water system design
  • Fracture flow and management of bedrock aquifers
  • Conjunctive use of surface and groundwaters
  • Protection of water quality, and its enhancement through recharge and watershed management
  • Effects of treated effluent storage and application
  • Migration of nitrates and other nutrients in shallow groundwater
  • Wetland protection and restoration: seasonal, riparian, and tidal/coastal systems
  • Development and management of brackish aquifers
  • Design of de-watering arrays
  • Technical support for preparing grant applications
