Why it matters
ASTM D3385-18 outlines the standard field procedure for measuring soil infiltration rates using a double-ring infiltrometer to manage water, design septic systems, and evaluate groundwater recharge. The test requires driving 300 mm and 600 mm diameter rings into the soil, followed by a one-hour presoaking period, before measuring the volume of water required to maintain a constant head.
