Determination of faecal pollutants in Torrens and Patawalonga catchment waters in South Australia using faecal sterols.

This research investigated faecal pollution by sterol profiling in two Adelaide metropolitan catchments in winter 2000 and summer 2001. Water was sampled from five sites on the River Torrens and two sites on Patawalonga river catchment. The steroids detected were coprostanol, epicoprostanol, cholesterol, cholestanol, stigmasterol, betasitosterol, and stigmastanol.
