The present study was carried out to study the impact of domestic wastes disposal on ground water quality at Delhi, India. Ground water is one of the major sources of drinking water in arid and semi-arid regions. Ground water quality data and its distributions are important for the purpose of planning and management. The samples of ground water were collected and analyzed for various physico-chemical parameters viz. conductivity, total dissolved solids (TDS), alkalinity, total hardness, calcium, magnesium, chloride, sulphate, nitrate, phosphate, fluoride, sodium and potassium. Among these parameters, TDS were found higher 1400, 1068, 1524, 1656, 840, 1106, 1540, 1330, 1900, 1960, 1914, 2061 mg/l at all the Ga1,Ga2, Ga3, Ga4, Ga5, Ga6, Ga7, Ga8, Ga9, Ga10, Ga11, Ga12, Ga13, Ga14, Ga15, Ga16 sampling sites respectively. TDS were observed beyond the desirable limits of BIS at all the sampling sites. Maximum value of TDS (2061 mg/l) was found at the sampling site Ga12 while the minimum value of TDS (1061 mg/l) was found at the sampling site Ga2. Maximum value of chloride (560 mg/l) was found at sampling site Ga4, while the minimum value of chloride (60 mg/l) was found at sampling site Ga5 and rest all other parameters were found within permissible limit. The present study concluded that the chloride and TDS in water samples were above to the desirable limit and below to the permissible limit of BIS and rest all other parameters were within desirable limit.
