The present study was conducted to compare the behavior of wheat straw, sawdust and biodegradable plastic (BP) as potential carbon sources for denitrification in groundwater remediation. results showed that a greater amount nitrogen compounds were released from straw than BP leaching experiments. In batch experiments, higher nitrate removal efficiency longer service life sawdust, which illustrated is most appropriate source stimulation activity. column able support complete at influent concentrations 50, 60, 70, 80, 90 mg NO(3)(-)-N/L, showing corresponding rates 0.12, 0.14, 0.17, 0.19, 0.22 NO(3)(-)-N.L(-1).d(-1).g(-1), respectively. These findings indicate applicable use nitrate-polluted
