Abstract: The Saharanpur town of Western Uttar Pradesh in north India is a sizable urban complex growing at a steady rate as a result of increase in population accompanied by spurt in industrial activities. The increasing urbanization and industrialization in Saharanpur city are making the ground water contaminated leading to . degradation in quality of ground water in shallow aquifers. Because of this reason, it is proposed to assess the ground water vulnerability of the shallow aquifers in the city where the major source of water supply to the urban populace is from shallow hand pumps and deeper tube wells. • There are various notable industrial units in the area such as a large paper mill, a tobacco company, distilleries, electroplating, and chemical units. These industrial units discharge waste effluents into the nearby drains, which finally meet the river Hindon. • Further the municipal effluents carrying sewage of the town also meet the river system adding to the waste load of the river. A total of about 33 locations were selected for monitoring ground water quality. In addition about 10 localities samples of surface water from the main drains and storm water runoff from residential & commercial areas of city have been collected after the rainy season. The water samples have been analyzed for physicochemical parameters (pH, EC, Temp, Ca, Mg, Na, HCO3, SO4, NO3 etc.), selected heavy metals (viz. Ni, Cd, Cr, Mn, Fe etc.) and bacteriological parameters (total coliforms & fecal coliforms). The chemical analysis of surface water in the area indicates high concentration of fecal coliforms, BOD iv • and COD at few localities, especially in the nalas and the sewage. The Piper Trilinear plots of chemical data indicate generally intermediate, to hard nature of ground water with its character changing to dominating carbonate hardness in the recharged postmonsoon samples. From Stiff diagrams it is observed that total cations and total anions are mostly well balanced with respect to its concentration, except four locations viz., DPT, D/S of Paondhoi Nala, U/S of Paondhoi Nala and Sabrika Bagh. The analysis of ground water at some places indicates excessive concentrations of heavy metals like copper, manganese and• feca] coliforms when compared to the quality criteria for drinking water. The reasons for high concentration of these heavy metals can be attributed to the direct disposal of industrial effluents to nearby drains. Similarly, the origin of high fecal coliforms can be traced to the presence of sewage in the nalas especially downstream of the sewage pumping station in the central part of the study area. A total of five geophysical resisitivity soundings and five Induced Polarization (IP) soundings were recorded at selected points in the area wherever space was available for laying down schlumberger sounding spread up to about 200 m (AB). The resistivity sounding data was interpreted using partial curve matching techniques. The IP sounding data was interpreted by using IX1D (Interpex) software. The characteristic resistivity and IP response ranges of different lithological units adopted after Sharma (2007) are given as under The geological interpretation of the geophysical data has confirmed absence of any gross pollution of the shallow groundwater though contamination by specific parameters can not be ruled out in the town. However, presence of clay horizons at deeper levels was confirmed at some localities.: v
