Background: Customary wetland changes location strategies primarily utilize restricted perception locales and ground-based perceptions of testing plots. In any case, this technique can't totally portray wetland hydrology and vegetation change data in space and it is difficult to acknowledge persistent perception of wetland changes on a period scale.

Water is considered as an essential resource on earth and the sources of fresh water are depleting due to increasing demand of population and different pollution sources. The purpose of this study was to analyze the physiochemical parameters of water. The samples were collected from 5 different drinking water sources and have been analyzed for pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Total Hardness (TH), Nitrates (NO3 2-) and Biological Oxygen Demand (BOD). The result showed that pH, EC, TDS, T. Hardness, (NO3 2-) and B.O.D. were ranged from 7.3 to 7.77, 237.3 to 323.3 μSm-1,475.33 to 876.57 mg/L, 316.33 to 831 mg/L, 1.32 to 2.94 mg/L, 4.59 to 49.6 mg/L. All these parameters were analyzed by the standard methods of APHA and measured within the standard drinking water quality values of WHO. Among all these water samples, the water sample taken from bored well from the Karewa fields showed the best results and suitable for drinking purposes and the the present investigation found that the maximum parameters were within range and could be suitable for irrigation purposes. The sample collected from river Jehlum suggested that the rate of pollution is increasing day to day when compared with previous papers.
