[Significance of fecal streptococci in the detection of bacteriologic contamination of drinking water].
Because of their increased environmental resistance faecal streptococci are a good indicator of a contamination dating back a long time. Under the new Federal German Drinking Water Regulations, examination of faecal streptococci is not mandatory. On the basis of 190 samples of water from natural springs it was shown that, if the water was examined only in respect of E. coli and coliform bacteria there were no objections in 22% of water that was faecally contaminated, so that such water escaped detection. Hence, it is advisable to perform the faecal streptococci test in water that is frequently or potentially infected with bacteria.
