Abstract
Faraday Base represents a small isolated community producing its own domestic water by desalination of sea water. During the Antarctic winter of 1986 (April to October), regular bacteriological examination of the water supply and surrounding sea took place. Samples were collected and examined every 2 weeks by the methods described in the Department of Health and Social Security Report No. 71, on the Bacteriological Examination of Drinking Water Supplies (DHSS, 1982), for membrane filtration and colony counting. The results of these examinations are presented in this paper. The results obtained suggest that water of good bacteriological quality was produced by the desalination plant, but some samples from the distribution system contained coliforms or presumptive Escherichia coli in small numbers. The possible reasons for this low-level contamination are discussed. No cases of gastroenteritis occurred on the base during this time.
