Hydrology and Hydrogeology Investigation Services

PT Geo Labora Indonesia provides comprehensive Hydrology and Hydrogeology Investigation Services to support safe, efficient, and environmentally responsible mining operations. Our services are designed to evaluate surface water and groundwater conditions that influence mine planning, pit slope stability, dewatering strategies, water supply, and environmental compliance.

Through industry-standard methodologies and advanced analytical tools, our team delivers accurate, science-based assessments essential for operational decision-making

Scope of Services:
1. Hydrological Surveys and Surface Water Assessment‍

• Measurement of rainfall, runoff, streamflow, and watershed characteristics.
• Assessment of flood potential, peak discharge, and catchment hydrodynamics.
• Development of surface water management plans for mining operations.
• Infiltration test

2. Hydrogeological Investigation and Groundwater Evaluation

• Geological and hydrostratigraphic mapping to define aquifer systems.
• Drilling and installation of monitoring wells/piezometers.
• Pumping tests, slug tests, and groundwater level monitoring.
• Analysis of aquifer properties, groundwater flow, recharge rates, and hydraulic conductivity.

3. Mine Dewatering and Depressurization Studies

• Evaluation of groundwater inflow into pits.
• Design and optimization of dewatering systems (well-points, pumping wells, drainage).
• Numerical groundwater modeling to predict water behavior under mining conditions.

4. Water Quality Sampling and Laboratory Analysis

• Assessment of surface water and groundwater chemistry.
• Evaluation of potential contamination, acid mine drainage (AMD), and environmental risks.
• Compliance testing based on applicable Indonesian regulations and international standards.

5. Hydrological and Hydrogeological Modeling

• Development of 2D/3D hydrological & hydrogeological models using professional software.
• Simulation of seasonal variability, inflow scenarios, recharge patterns, and mine closure conditions.
• Prediction of long-term impacts of mining on water resources.

6. Design of Water Management Systems

• Surface runoff control, diversion channels, settling ponds, and water storage facilities.
• Groundwater control through dewatering wells, horizontal drains, and depressurization systems.
• Recommendations for operational and long-term water management strategies.
