| Abstract: | The distribution of faecal coliform densities found in New York Bight sediments indicated that sewage sludge material has contaminated areas extending 11 km north and 37 km south from the disposal site. A high degree of confidence for enumerating faecal coliforms in marine sediments was demonstrated by standard water methodology since 82.3% of the faecal coliform group isolated were Escherichia coli. This study also indicated that marine sediments could be stored 4 days at 4°C without appreciable changes in the faecal coliform count, and that, in situ, faecal coliforms would persist longer when sediment temperatures were low. |
