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 injection wells has supported projects related to seawater intrusion barriers and groundwater replenishment with advanced treated wastewater.

  • Geologic characterization
  • Formation sampling and logging
  • Aquifer zone isolation testing
  • Geophysical log analysis and interpretation
  • Grain size analysis
  • Final well design
  • Well construction observation, including:
    o Single-point monitoring wells
