Abstract:

The standard (heterotrophic) plate count proved the most valuable and sensitive tool for routine monitoring of water quality and treatment efficiency. The highest bacterial counts in Lake Qarun water during Summer and Spring were in parallel with high water temperatures during these seasons. The bacterial counts increased with increasing turbidity (low transparency) especially in El-Batts and El-Wadi Drains and at mixing areas in the lake, in front of the discharging points of both drains. In addition to total bacterial counts(TBCs) or heterotrophic plate counts(HPCs)the most common bacteria used as indicators are total coliform(TC), including faecal coliform(FC), bacteria as well as faecal streptococci(FS). The highest counts of TC and FC in water during Summer and Spring were in harmony with high water temperatures during these seasons. On the other hand, the highest counts of bacterial indicators of faecal pollution (TC, FC&FS) in both drains may reflect the pollution by crude  sewage to which they may subject. The ratio FC/FS points the source of faecal pollution whether it is human (>4) or animal (<0.7) . During the present study, FC /FS ratios were either less than 0.7 or between 0.7 and 4, indicating animal and mixed faecal pollution, respectively. In conclusion, The highest counts of bacterial indicators of faecal pollution (TC,FC&FS) during the present study may reflect the high levels of recent and continuous pollution by crude  sewage to which the lake may subject.
