| Abstract | ||
| Twenty water samples were collected from ten shallow house wells adjacent to their house septic tank with 3 to 10 m in between, in Baiji city – Salah Aldeen Governorate. Two repeated sample were taken from each well during the period between July to Dec. 2013 .Biological tests were done for these water samples. These tests were represent the total aerobic and non-aerobic bacteria ,Coliform and Staphylococcus bacteria and the detection of rotaviruses. Identification of aerobic and non-aerobic bacterial colonies. Results showed that water well samples contain variable microbial content that reach up to 162×104cfuml .Most of the samples have coliform and Staphylococci bacteria with a numbers of 169×103 and 110×104cfuml respectively. The results also showed that total bacterial number congenitally reciprocal with the distance between the well and septic tank. Identification for aerobic bacteria revealed that there are four enteric bacterial species in addition to Staphylococcus aureus and Bacillus cereus . However, the identification of anaerobic bacteria result with nine different species distributed variably through the samples. The Rotaviruses indication test result positive in 10 % of the samples .These results indicate that these well water have potential unsafeusage for various human consumption activities. | ||
