Twenty one villages use water from the nallahs and fecal coliform contamination was from 4 - 500 cfu at the source, 1 -1350 cfu in the beginning of the distribution system, 44 - TNTC in the middle and 110 - TNTC in the end of the distribution system.
In our case, the [10.sup.-2] dilution was excluded because most of the plates were scored as TNTC. We would also recommend excluding the [10.sup.-5] dilution because colony counts were low and, hence, more prone to sampling error than dilutions with large colony counts.
