The paper describes the main results of an investigation which examined the movement of septic tank effluent through soil/overburden to groundwater at three geologically and hydrogeologically differing sites using a range of chemical and biological tracers. The results of the study demonstrated that a single tracer type cannot be used to accurately monitor the movement of all effluent constituents through soils and groundwater. The results also indicated that the combined use of nitrate and/or bromide ions and endospores of Bacillus globigii would give an accurate indication of the movement of both the chemical and biological constituents of septic tank effluent.
