	abstract = {The use of faecal coliform to faecal streptococci ratios as indicators of the source of faecal pollution has become popular. However, this methodology has been attacked on the grounds that the differential die-away rates of FC and FS invalidate the use of the ratio. Data is presented here to show that this differential die-away can in fact strengthen the value of the FC:FS ratio as a means of distinguishing human from non-human pollution. It is concluded that initially high FC:FS values which fall indicate human contamination, whereas initially low ratios which subsequently rise suggest a non-human faecal source.},
