Abstract: A laboratory study was undertaken to determine the ability of four Oahu soils, Lolekaa, Lahaina, Manana, and Wahiawa, to remove ammonia, ABS, and coliforms from water percolating continuously through saturated soils. The soils utilized were chosen on the basis of their wide occurrence on the island in areas where percolating water may enter directly and in quantity into the ground water body that prinipally provides the island's domestic water supply. All four soils had a high clay content and low pH. All soils were effective in the removal of ammonia and ABS. One-hundred percent breakthrough for ammonia occurred after a throughput volume of 345 to 470 times the gross soil sample volume. For ABS it was 15 to 53 times the gross soil sample volume. The total exchange capacity for ammonia ranged from 29.3 to 50.1 micro-grams of ammonia per gram of soil. The total absorptive capacity for ABS ranged from 8.6 to 36.4 micro-grams of ABS per gram of soil. The applied concentration of ammonia was approximately 7.1 mg/l as found in a primary clarifier effluent and that of ABS was approximately 5.5 mg/l as found in a final clarifier effluent.
The results of coliform removal from percolating liquids were not conclusive because of small soil samples and the loading procedures.
