MONITORING THE SANITARY CONDITION OF GROUND WATER USED IN SOME POULTRY FARMS IN GIZA GOVNRNORATE

One hundred and twenty ground water samples were collected from some poultry farms located in different areas of Giza governorate. The collected samples were subjected to chemical analysis and microbiological examinations. The mean values for the pH was ranging between (6.98 + 0.10 and 7.35 ± 0.45), ammonia (0.008 ± and 0.1 + 0.2 mg/1.) nitrite (0.01 ±03 and 1.08 ± 2.05 mg/1.), nitrate (0.03 5 0.07 and 4.26 ±7.88-mg/1.), phosphate (0.001 ± 0.003 and 0.48 ±0.95-mg/1.), chloride (35.46 ± 8.95 and 730.2 ±645.10 mg/1.}, and total hardness (139.46 + 46.05 and 781.28 ± 519.19 mg/1.).Regarding the microbial findings the mean value for the total fungal and bacterial counts ranged from 1.46 ± 2.18 to 11.3 ± 11.14 CFU/ml.and 17.33 ±49.80 to 340±193.39 Cf'U/ml. re- spectively, while the total coliform counts ranged from 0.6 ± 2.24 to 72 + 186.52 coliform colony/100 ml. Seemingly, the obtained results of high amount of minerals and microbial findings in the investigated ground water samples were attributed to the variable sources for water pollution in these sub- urban areas, such as septic tanks, cesspools, un- hygienic disposal of sewage and different with improper construction of wells, overuse of fertilizers and herbicides and the agriculture runoff. The exception of that was the area of 6 October in which the human activities arc far away from farm buildings and water sources. Accordingly it is recommended that periodical monitoring of water supply in all poultry farms is important, especially ii suburban areas, while the Poultry producers should by aware of the nature of the land in which their farms are located. Also renewal, re-sitting, reconstruction or increasing the well depth is a decision that should  be taken in the correct time.
