Abstract
In developing countries, Arsenic concentrations overhead satisfactory values for drinking water have been identified in many countries and this should, therefore, it is a global concern. The presence of arsenic in subsurface aquifers and drinking water systems is a possibly serious social health hazard. The existing population growth in Pakistan and other developing countries will have a straight bearing on the water zone for meeting the domestic, industrial and agricultural needs. Pakistan is about to exhaust its accessible water resources and is on the verge of becoming a water deficit country. Water contamination is a serious threat in Pakistan, as almost 70% of its surface waters, as well as its groundwater reserves, have contaminated by biological, organic and inorganic pollutants. In some areas of Pakistan, a number of shallow aquifers and tube wells are contaminated with arsenic at levels which are above the recommended USEPA arsenic level of 10 ppb (10 g L−1). Opposing health effects including human mortality from drinking water are well documented and can be attributed to arsenic contamination. All of the areas of Bannu district was studied. The present paper reviews appropriate and low-cost methods for the elimination of arsenic from drinking waters.

The electrical conductivity of 28 sample is in range and 5 sources sample was not found in range
Summary
More than 70% of the Earth’s surface covers by water, but freshwater less than 3% of this. Poor water quality is main environmental and health-related concern in Pakistan. Both groundwater and surface in the country are polluted with various toxic component and microorganisms [3]. Within the last years it has become increasingly plain to most of us that the sufficiency of freshwater supplies is a significant problem in arid regions. It proves an apparent negative impact of climate change as a variability in precipitation amount and distribution together with rising temperatures.
