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
- Formation sampling and logging
- Aquifer zone isolation testing
- Geophysical log analysis and interpretation
- Formation grain size analysis and filter pack selection
- Final well design
- Well construction observation, including:
o Single-point monitoring wells
o Deep nested monitoring wells
o Deep monitoring well clusters
o High-capacity, large-diameter municipal supply wells
o High-capacity, large-diameter injection wells
- Chemical and mechanical development plans and oversight
- Planning and directing pumping tests and data analysis
- Spinner log analysis and interpretation
- General and depth-specific water quality sampling, flow analysis, and water quality assessment
- Well condition assessment
- Well rehabilitation planning, technical specifications, and oversight
- Well repair and liner design-and-construction oversight
- Experience in using non-traditional filter pack media (spherical glass beads)
