Groundwater Exploration Geophysics

Supports well siting, shallow aquifer screening, and hydrogeologic baseline studies before drilling or pumping tests.

Definition

What this method is

Groundwater exploration uses resistivity-led and integrated geophysical workflows to locate likely aquifer zones and constrain hydrogeologic interpretation.

Supports well siting, shallow aquifer screening, and hydrogeologic baseline studies before drilling or pumping tests.

How It Works

From field measurement to interpreted model

  1. 1Project objectives and expected water-bearing horizons are defined during scoping.
  2. 2Resistivity and supporting datasets are acquired across the target area.
  3. 3Interpretation highlights likely aquifer zones and areas needing follow-up verification.

When to Use

Best-fit conditions for this method

  • Well siting and aquifer studies
  • Barangay, industrial, or project water-supply screening
  • Pre-drilling planning where groundwater uncertainty is high

What It Can Help Identify

Subsurface features and signals

  • Potential water-bearing zones
  • Conductive or weathered intervals of interest
  • Areas where drilling should be prioritized or avoided

Deliverables

What you receive

  • Target zones and recommendations
  • Hydrogeologic interpretation notes
  • Planned follow-up investigation suggestions

Typical Outputs

What the data looks like

  • Aquifer target maps
  • Depth-to-target summaries
  • Priority drilling zones

Applications

Common applications in the Philippines

Water resources projects

Industrial water supply planning

Municipal and private well-siting programs

Method Limitations

What this method cannot do alone

  • Direct confirmation is required through drilling and tests, especially where layers are laterally variable.

Geophysical results are interpreted models based on measured physical property contrasts. Results should be correlated with boreholes, test pits, drilling, geological mapping, laboratory data, or other direct investigation methods where required.

FAQs

Frequently Asked Questions

Can groundwater exploration identify the exact well yield?

No. It helps identify favorable zones, but drilling and pumping tests are still needed to confirm yield and water quality.

What is the main output of a groundwater exploration survey?

The main output is a target interpretation that highlights zones with better groundwater potential and the reason those zones were selected.

What data helps make groundwater interpretation stronger?

Surface geology, borehole logs, nearby well records, and site access information help the interpretation become more defensible.
