: Drive the outer ring into the soil to a depth of approximately 150 mm (6 in.). Concentric Placement
One famous anecdote from the 1990s: a landfill liner design in Florida relied on lab permeability tests showing clay was nearly impermeable. But field tests using D3385 found infiltration rates 100 times higher—because natural cracks and wormholes existed. The design was changed, preventing a major groundwater contamination risk. astm d338518 pdf

ASTM D3385-18, the "Standard Test Method for Infiltration Rate of Soils in Field Using Double-Ring Infiltrometer," outlines a field procedure using a 12-inch inner and 24-inch outer ring to determine soil permeability. The constant-head method is suitable for measuring liquid infiltration in various soils, excluding those with high gravel content or excessive shrinkage. The full standard can be purchased directly from the ASTM Store . The design was changed, preventing a major groundwater
