ENGEO provides hydrogeologic services related to groundwater resource assessment, sustainability, water quality, and groundwater supply.

Our hydrogeologists are known for planning, modeling, design, construction management of groundwater supply wells, monitoring wells in nested and cluster configurations, and injection wells. Our experience with the design and construction management of deep monitoring wells and injection has supported projects related to seawater intrusion barriers and groundwater replenishment with advanced treated wastewater. ENGEO’s services include:

  • Preliminary well design and site selection
  • Preparation of technical specifications, special provisions, bid forms, plans, and engineer’s estimates
  • Geologic characterization
