This study aims at characterising the probable 99 faults of region by carrying out the probabilistic seismic hazard analysis for different districts of Kashmir valley by preparing seismic hazard curves and the contour maps of three ground motion parameters, namely, peak ground acceleration (PGA), short period Sa (0.02 s) and long period Sa (1.0 s) spectral acceleration for 50, 100, 500 and 2,500 years return periods using the Atkinson and Boore (2006) GMPM and an updated catalogue containing event records till April 2018. On comparison with the earlier studies it was found that there is the need to consider the local site variability in the hazard computation. Shopian, Budgam, Baramulla and Kupwara were found to have much higher seismic hazard levels as compare to other districts. The estimated hazard values for these regions highlights that the zonal spectral values are underestimated in the Indian Codal provisions. The maps, hazard curves and UHRS so developed can be used for assessing the seismic vulnerability of the existing structures and constructing risk maps for the selected areas.

Water Quality Analysis of Different Sources of Rajouri Town in Jammu and Kashmir was done to know weather water which the people are drinking in this area is fit for the said purpose or not. Three water samples were collected in July from different locations and then analysed in Public Health Engineering (PHE) Division Rajouri lab using the methods recommended by Indian Standard Drinking Water-Specification (Second revision). The average value of the three was considered as the value of particular parameter. The analysis was done for some important physical and chemical parameters like colour, taste , odour, turbidity, pH, TDS, Alkalinity, Hardness , Chloride Content, Calcium, Copper, Iron, DO, manganese, sulphates, and nitrates and fluorides. The values were than compared with the limits set by Indian Standard Drinking Water-Specification (Second revision). It was found that water on the whole for Rajouri Town was found to be safe on most of the locations except (L4) location near Abdullah bridge at Bela Colony, here almost all the parameters except TDS were exceeding the acceptable limit prescribed by IS code. The locations which was safest for drinking purposes among all was the Eidgah hand pump (L7) followed by spring near Power house (L3) and then the spring near Rajouri Airport (L8). However at some location where certain parameters like TDS hardness and iron etc were exceeding the prescribed limit the water to be should be boiled before being used for drinking purpose.
