Abstract A biological treatment process employing immobilized microbial populations was field‐tested on contaminated groundwater containing elevated concentrations of volatile organics and organic pesticides. The process consisted of parallel biological reactors, one a continuously stirred biological reactor packed with pall rings (Conventional Biotower) and the other a packed bed reactor operated in a plug flow configuration (Manville Packed Bed Reactor). Gas chromato graphy/mass spectroscopy analyses for forty two groundwater contaminants in feed and treated streams indicate that both reactors were very effective in the reduction of organophosphates and organochlorines.
