An apparatus for the in situ, sequential anaerobic and aerobic treatment of contaminated water is disclosed which includes definition of a treatment flow path for water from a source of contaminated water and division of this flow path into a first region and a second region. An anaerobic bioreactor is disposed in the first region for anaerobic biodegradation of the contaminants within the water. An aerobic bioreactor is disposed in the second region, for aerobic biodegradation of contaminants within the water. The apparatus also causes the water to flow from the source of contaminated water into the treatment flow path, through the anaerobic bioreactor in the first region, through the aerobic bioreactor in the second region, and then back to the source of contaminated water. Also disclosed is a method for treating contaminated water, which includes the steps of defining a treatment flow path for water from a source of contaminated water, and dividing the flow path into distinct anaerobic and aerobic regions. Then the water is drawn from the area of contaminated water into the anaerobic region and anaerobically treating the contaminated water. Then the anaerobically treated water is caused to flow to the aerobic region, and the contaminated water is aerobically treated. Then the treated water is returned to the area of contaminated water.
