¹Values are means of triplicate determinations from three independent trials; ± = standard deviation; TCC = total coliform count; TVC = total viable counts; BS = Bolgatanga sample; NS = Navrongo sample; GS = Bongo sample; CS = Chiana sample. ²Means with the same letter as superscript in a column are significantly different ( < 0.05).
