Shallow Bedrock Well Installation

Project Overview:

A global company specializing in the energy, infrastructure, and environmental sectors engaged Summit to preclear, drill, and install three shallow bedrock monitoring wells in Roselle, NJ. The wells were advanced to depths of 65-75 feet deep to support environmental groundwater characterization beneath a constrained urban site. Summit performed all drilling, well installation, waste handling, and development activities.

Challenge/Conditions:

The project was completed within a tight work area, requiring careful rig positioning, controlled staging of materials, and efficient movement of equipment to avoid disruptions to nearby operations. Limited access also required disciplined waste management and containment procedures.

Services Provided:

• Preclear/vacuum extraction of three drilling locations to 5 ft
• Air rotary drilling into shallow bedrock
• Installation of three 6" steel casings set 10 ft into bedrock
• Advancement of boreholes to targeted depth
• Geophysical logging of each borehole to determine depth of screened intervals
• Installation of 2" PVC monitoring wells extending 15 ft beyond casing
• Placement of 5' well screens and construction of flush-mounted manholes
• Drum management of soil and water; staging of IDW onsite
• Well development

Solutions/Approach:

Summit began with vacuum extraction and preclearance to safely expose and prepare each drilling location. Using air rotary methods, the crew installed 6" steel surface casing and advanced boreholes through the shallow bedrock to reach productive groundwater intervals. Each borehole was drilled to a target depth of 65-75' below ground surface. Geophysical logging was performed on each borehole to ensure the screens were set over a targeted fracture zone. Once data was compiled, the boreholes were converted into a 2" PVC monitoring well with a 5-foot screen to support high-quality groundwater sampling. Work areas were tightly controlled due to site constraints, with soil and water drummed and staged for proper handling. The team completed well development and installed flush-mounted manholes to allow secure, low-profile access.

Outcome/Results:

All three monitoring wells were successfully installed to target depths despite limited workspace. Summit's customer received structurally sound, fully developed wells ready for sampling and long-term monitoring. The project was completed safely and efficiently, demonstrating Summit's capability to execute precision drilling in space-restricted urban environments.
