Water samples to be analyzed should be collected in sterilized 1 L plastic bottles or borosilicate glass precleaned and rinsed with distilled or deionized water. Samples should be unfiltered and unpreserved, except if chlorinated in which case 0.01% v/v sodium thiosulfate should be added. The sample should be kept at 4°C until it is ready for analysis usually within 24 h of collection. Information on equipment to be used for bacteriological analysis, types of media to use, and their methods of preparation and storage can be found in APHA [2] and the British Columbia Environmental Laboratory Manual [16].
