50 ground water samples collected from Kalyobia Governorate and subjected to physical, chemical and bacteriological examination for determination of their hygienic conditions for animal consumption.
Turbidity units of examined samples ranged from 5-20 units, 43 sampl es were colourless and 7 samples were faint to very faint colour. Ph Values ranged from 7.5 to 7, total solids from 1-14 mg/L while ammonia contents from 1-100 mg/L in 25 samples, nitrite found in 16 samples and nitrate in 3 samples, chloride, total hardness and organic matter contents ranged from 17-682 mg/L, 60-125 mg/L and 0.4-59 mg/L respectively. T.B.C. per 1 ml. of examined water ranged from 15-30500 at 37°C and from 9-9000 at 20°C, Coliform count ranged from 2-1100 in 25 samples and E.coli type 1 count 2-1100 in 19 samples (MPN/100 ml).
Milk powder test proved to be a reliable easy to do field test.
