Assessment of Ground Water Quality in some villages of Lachhmangarh Tehsil-Western part, Sikar District, Rajasthan, India

Abstract

Groundwater quality is an important criterion for evaluating of water. It is affected by different natural as well as anthropogenic processes. The aim of study is physico-chemical analysis of groundwater quality in some villages of eastern part of Lachhmangarh tehsil, District Sikar in pre monsoon and post monsoon season. All ground water samples were collected from Hand Pumps, Open Wells and Tube Wells and analyzed for physico chemical parameters namely Temperature, pH, Electrical Conductivity, Total Alkalinity, Total hardness, Calcium hardness, Magnesium hardness, Total Dissolved Solid, Dissolved oxygen, Fluoride, Nitrate, Carbonate, Bicarbonate, Chloride, Sulphate, Calcium, Magnesium, Sodium and Potassium. The standard methods of APHA were used to analysis of samples. The quality of groundwater has been assessed by calculating correlation coefficient (r) for every pair of parameters. The fluoride concentration in four different zones ranged from 3.5 mg/L to 7.2 mg/L. Result showed that fluoride concentration in all samples were exceeding the permissible limits prescribed by Bureau of Indian Standard (BIS) and World Health Organization (WHO). Due to the higher fluoride level in drinking water several cases of dental and skeletal fluorosis have appeared at alarming rate in this region.
