Percolation and Permeability In-Situ Testing

Service Overview

GeoStructures is highly skilled in site characterization and testing for stormwater infiltration to determine the feasibility of groundwater recharge. Explore how we can assist stormwater engineers and site developers with our range of services for designing engineered infiltration systems.

Service Offerings

Soil Survey Maps (USDA) Interpretation

Interpret USDA soil survey maps to identify soil types and characteristics relevant to stormwater infiltration and groundwater recharge.

Soil Profiling Using Deep Test Pits or Borings

Conduct soil profiling through deep test pits or borings to assess soil layers and their suitability for infiltration systems.

Documentation and Rating of Redoximorphic Features (Mottling)

Document and rate redoximorphic features, such as soil mottling, to understand soil drainage conditions and aeration status.

Identifying Promising Strata for Infiltration and Permeability Class Rating

Identify soil strata with potential for effective infiltration and assign permeability class ratings to aid in system design.

Groundwater Table (Phreatic), Perched Saturation Zones, and Seasonal High-Water Table (SHWT)

Determine the depth of the groundwater table, perched saturation zones, and seasonal high-water table to guide infiltration system planning.

In-Situ Testing Using a Double-Ring Infiltrometer

Perform in-situ testing with a double-ring infiltrometer to measure soil infiltration rates and evaluate suitability for groundwater recharge.

Borehole Infiltration Testing

Conduct borehole infiltration testing to assess the permeability of soil layers at various depths.

Percolation Testing

Execute percolation tests to measure the rate at which water infiltrates the soil, providing critical data for infiltration system design.

Basin Bottom Adjustments for Improved Infiltration

Recommend and implement adjustments to basin bottoms to enhance infiltration performance and groundwater recharge efficiency.
