Most NNP values ranged between 400 to 830 kg CaCO 3 /t, which is equivalent to approximately 40% to 80% the theoretical neutralization potential of calcite or pure limestone (1000 kg CaCO 3 /t) . The NPR ranged from 26 to over 399 (ratio not calculated for AP less than the detection limit) ( Table 2 ).
