This study was conducted to investigate the drinking water quality of Bannu District. Water samples were collected from tube well and bore well, from the whole District. The samples were analyzed for physiochemical water quality parameters such as color, taste, odor, temperature, turbidity, pH, conductivity, dissolved oxygen (DO), salinity, alkalinity, hardness, calcium and magnesium hardness, chloride, phosphate, sulphate, sulphide, nitrate, sodium and potassium. The results of analysis are given in the tables. All the samples were colorless, odorless and tasteless, temperature is ranged from 32.4-33.4c0, Electrical conductivity ranged from 0.40-1.12 S/cm, pH ranged from 6.04- 6.90, turbidity ranged from 11-12 mg/l, DO ranged from 2.10 - 2.19 mg/l, hardness ranged from 145 - 300 mg/l, calcium hardness ranged from 75-225 mg/l, magnesium hardness ranged from 25-95 mg/l, alkalinity ranged from 240-425 mg/l, chloride ranged from 15-67.47 mg/l, phosphate ranged from 5.47-6.90 mg/l, sulphate ranged from 230.4-465.6 mg/l, sulphide ranged from 0-5.36 mg/l, nitrate ranged from 8.1-9.8 mg/l, sodium ranged from 5-75 and potassium ranged from 0-10 mg/l.

Earth the planet we inhabit, is a single, living pulsating entity and the human race an interlocking extended family. The land water and the atmosphere which constitute it environment, support .37 million species of plants and 1.2 million species of animals. Human interference into the environment has upset the ecological balance of our planet. Exploitation of non renewable resources has created havoc and if allowed to continue can disrupt life on this planet. Some of the most dramatic cases with environment are man mad fires slashes burn agriculture, mineral mining, dumping of sewage and industrial wastes, introduction of new transport system into natural environment, persistence of nuclear testing and disposal of nuclear waste, the threat of Global worming and the attenuation of our ozone shield, the havoc of deforestation leading to destruction of many species of flora and fauna, devastation of landscape by herbicides introduction of pests into new areas, over population, overgrazing, coupled with drought extensive air and water pollution, and the poising of the food chain. All these are the problem which the human race shares in common.

Life on this planet is based on the continuous cycle of elements. The massive mobilization of natural resources and the industrial synthesis of chemicals have generated number of problems as a consequence of limited incorporation of natural and synthesized molecules into ongoing biological cycle. Number of aromatic compounds has wide range of applications. Among these nitro aromatic compounds like 2,4,6-tri-nitrotoluene (TNT) is more recalcitrant (Nunez et al.,1998). TNT was first made in 1863 by a German chemist, Joseph Wilband, but its potential was not seen for several years, mainly because it was so hard to detonate and because it was less powerful than other explosive. Amongst its advantages, however, are that it can be safely melted using steam or hot water and so poured molten into shell cases. It is also insensitive that, for example, in 1910 it was exempted from the British 1875 Explosive Act, from actually being considered as an explosive for the purposes of manufacturing and storage.The US EPA has listed TNT as a priority pollutant and has recommended its removal from contaminated sites. The highest amount of TNT was produced at the end of World War II.
