DRILLING, CORING & SUBSURFACE EXPLORATION
Subsurface investigations are a critical component of environmental due diligence and engineering, providing insight into groundwater, contamination risks, and surface stability. This data is essential for evaluating environmental impacts and developing effective mitigation strategies. Rock Leaf Water Environmental is equipped to meet these needs promptly and accurately with our GeoProbe drill rig, hydro-excavator, and seasoned environmental staff.

In-Situ Chemical Oxidation (ISCO) Injection
ISCO injection is a remediation technique used to treat contaminated soil and groundwater by introducing chemical oxidants directly into the subsurface via wells or borings. This process oxidizes and breaks down pollutants into less harmful substances.
Piezometer Installation
Piezometers are instruments installed into boreholes or wells to collect data on groundwater pressure within soil and rock formations, providing information to monitor groundwater flow and assess the impact of environmental activities.
