Abstract
The present study is carried out to detect of indicators for bacterial pollution of groundwater for six shallow wells in many villages of Sharqat , it used for different purposes such as (irrigation, livestock watering, domestic, etc) . Results of the study refers that, temperature of groundwater between (14-26)C° are effected by changes of air temperature . Amount of total dissolved salts are effected by geological formation of study area, which are ranged between (1232-5234)mg/l . Dissolved oxygen have reversible relationship with total bacteria, ranged between (1.8-8.4)mg/l . Sulphates are ranged (434-786)mg/l . Wells almost polluted with microorganisms through : septic tank, animals, sewage , and dust . Many environmental factors such (organic matter, oxygen, carbon dioxide , etc) increase or decrease numbers of total bacterial count which ranged (20-70×103) cell/100ml in May and December at wells 4 and 5 respectively . Maximum value for number of coliform >2400 cells/100ml through almost study period in well 6 , but minimum value are <3 cells/100ml at different months through study period in wells 3,4,and 5 . Total feacal coliform bacteria number >2400 cells/100ml at (April, May, and July) in well 6 , , but minimum value are <3 cells/100ml at different months through study period in wells 3, 4, and 5 .
