Abstract |
The fate of nitrates as they travel through a long porous column at a slow rate was observed in this study with temperature and substrate materials variable. During a one month period of flow with pore velocities averaging up to 21 centimeters per day, losses as high as 89 percent were found for a methanol treatment at 24 degrees C while for 13 degrees C losses were reduced to 46 percent. A sawdust substrate material resulted in very little reduction of nitrate concentrations at 24 degrees C and actual increases (presumably from mineralization) at 13 degrees C.
