A sealed double-ring infiltrometer (SDRI) was developed for in-situ measurements of the hydraulic conductivity of earthen liners and covers. The characteristic of the SDRI that distinguishes it from other infiltrometers is a sealed inner ring, which permits measurement of low infiltration rates and minimizes problems with temperature fluctuations and evaporation. Two SDRI's were used successfully at a waste disposal facility near Niagara Falls, New York.
