The Current and Critical Drinking Water Quality of Flood Affected Villages of District Charsadda Khyber Pakhtunkhwa (Pakistan)

摘要

In this study, drinking water samples were collected from different villages of Nisatta, (District Charsadda) which was affected by a heavy Monsoon flood 2010 were analyzed Bacteriolgically and Chemically. The results were evaluated with WHO drinking water standards. Bacteriolgically TPC were found in the range of 9 X 106 -9 X 101 cfu/ml. TCB were calculated in the range of >1600–14MPN/100ml. 72% analyzed samples were contaminated with Escherichia Coli and Pseudomonas aeruginosa. TFC and Shigella were present in all the analyzed samples. Vibrio cholerae was present in all samples except one sample. 54% samples were contaminated with Salmonella. 63% samples were contaminated with Staphylococcus aureus. Chemically data showed that variation of the investigated parameters in water samples as follows: pH 6.77-7.42, Conductivity (μS/cm) 2200- 492, TDS (mg/L) 1419-320, TSS (mg/L) 16-3, Total Hardness (mg/L) 56 - 556, Calcium (mg/L) 36 - 336, Magnesium (mg/L) 20-260, Total Alkalinity (mg/L) 216 - 732, , Chlorides (mg/L) 14-344, Sulphate (mg/L) 42-270, Sodium (mg/L) 121–357, Potassium (mg/L) 8.0 - 600 and Nitrates (mg/L) 0.16–0.23. P-Alkalinity (mg/L) was not detected. Therefore, the results showed that there was a great contamination in drinking water of the under studied villages.
