Groundwater aquifers are naturally replenished by the infiltration of precipitation and stormwater through the ground surface and into the subterranean aquifer.

Engineers often design stormwater management features to encourage more infiltration and less runoff of stormwater into the sewer systems. Measurement of the capacity of a soil stratum to infiltrate water is a field test that is critical to effective infiltration design.

CGCG has extensive experience in a wide variety of infiltration testing methods and reporting, including percolation (perc) tests, borehole tests, single and double ring infiltrometer tests, and permeameters.
