PHYSICO-CHEMICAL CHARACTERISTICS OF GROUNDWATER OF AJMER CITY AND ITS NEIGHBOURING AREAS DURING PRE- MONSOON SEASONVinita Gupta and Subroto DuttaAbstract It is a well known fact that clean water is absolutely essential for healthy living. Polluted water causes problems of health and leads to water borne diseases, which can be prevented by taking suitable measures.The study area, i.e. Ajmer city is the fourth largest city of Rajasthan and has a population of 485575 according to 2001 census.Area covered by Ajmer city is 24 1.50 sq.km. and lies between 26°20'N to 26°33' N Latitude and 74°35' E to 74043' E Longitude. Thirty-five ground water samples from the most preferred drinking water sources were collected from Ajmer City and its neighbouring areas and were analyzed for pH, electrical conductivity,TIDS, total hardness, calcium hardness, magnesium hardness, total alkalinity, sodium, potassium, fluoride, sulphate and nitrate.The minimum and maximum values of concentration of various parameters are found to be high.The analysis also indicated that water at most of the places like,Tabijii,Ajesar, khanpura etc. is slightly hard, contaminated and hence unsuitable for drinking purpose. Level of fluoride is found to be high in areas like Makadwali, Chaursiyawas etc. It may have adverse effect on health of people residing in the study area, thus suggesting an urgent need for proper remedial measures.
