Abstract

The current condition of nitrate (NO3-) contamination in groundwater and its effect on the marine environment were evaluated in the Yellow River Delta, northeastern China. In the groundwater recharge area, NO3- contamination is suggested to be more severe compared with that in the groundwater discharge area. Also a relatively large amount of nitrogen is estimated to have accumulated in the aquifer of the recharge area. However, distribution of nitrate-nitrogen (NO3--N) concentrations and δ15N implied a denitrification process in the aquifer of the coastal area. In addition, a high rate of denitrification was indicated there by in situ experiments involving injected tracer water with high concentrations of NO3--N. Based on these results, it is suggested that a large amount of nitrate will be removed before it reaches the sea.
