Infiltration Testing

At Geo Costa Rica, we offer infiltration testing to assess soil permeability and determine the capacity of surface water to recharge aquifers. These tests are essential for hydrogeological studies, contaminant transport analysis, and water balance evaluations, among others.

What Is Infiltration Testing?

Water infiltration into the soil is a key process within the hydrological cycle. Infiltration tests help determine how much surface water remains in the soil, how much flows toward water bodies, and how much contributes to aquifer recharge. The infiltration rate varies depending on the site's geological characteristics: it tends to be higher in sandy or rocky soils, and lower in clayey soils.

Why We Conduct Infiltration Tests

Infiltration tests allow us to determine the soil’s permeability, which is key for:

Designing drainage systems and infiltration fields, such as those used in septic tanks.
Evaluating the transport of contaminants from the surface to aquifers.
Developing hydrogeological models and water balance studies.
Meeting SETENA and SENARA requirements for environmental impact assessments.

Infiltration Test Methods

At Geo Costa Rica, we apply different methods based on terrain conditions. The most common include:

Lefranc
Double Ring
Pourchet

These tests provide accurate estimates of the infiltration rate and the soil’s capacity to retain or transmit water to aquifers.

Applications of the Tests

Infiltration tests are essential for:

Determining soil permeability.
Analyzing in-field contaminant transport.
Supporting hydrogeological studies required by SETENA and SENARA.
