Table 3: Daily high and low temperature that water samples were exposed to, as well as the nitrate-N concentrations and % change from the baseline concentration. The baseline concentration is the Day 0 Control for each water source. nitrate-N concentrations for this method. With the exception of Day 14, the tile water concentrations all increased.
