Study on the Water Quality of District Swabi Pakistan

Arsenic content in water has proven deadly in many areas of Pakistan due to the lack of knowledge in regard to the purification of the content of water. One such area of District Swabi, Pakistan, has been included in the following study where arsenic content can be found in water at an elevated level. Arsenic content of more than 18 ppb was found. The water quality analysis indicate the concentration of pH, color, turbidity, chloride, TDS, nitrates and Total Coliform was observed to be 9.3, 5.5 units, 5.2 NTU, 105 mg/L, 922 mg/L, 2.3 mg/L, and 35 MPN/100mL. Both lime and alum are the cheapest available options to remove arsenic. Using 08 mg/L of alum can remove more than 55% arsenic and 61% turbidity. Whereas, lime at an optimum concentration of 16 mg/L, can removed more than 51% arsenic and 47% turbidity.
