摘要：

We studied the possibility of cleaning groundwater contaminated with nitrate ions using indigenous bacteria. The groundwater occurs in a site located near a former vegetable farm near Albuquerque, New Mexico (USA) and contains up to 500 mg.L-1 of nitrate ion. Batch and column experiments using groundwater and local sediment showed that indigenous bacteria catalyzed the nitrate ions reduction. Sodium acetate was selected as the best carbon source for the in situ application. As expected, the best conditions for denitrification were encountered in situ. Nitrate ions and their byproducts were reduced to nitrogen gas within 5 days.
