Seasonal Variation in Physico Chemical Parameters of Ground Water of Merta City, Nagaur

Abstract

The influence of seasonal changes on the properties of the water in Merta City, Nagaur, Rajasthan was investigated. Composites samples from different sites of Merta City were collected and assessed for both pre-monsoon and post-monsoon seasons. The values of the various parameters were as follows: pH 7.3 to 8.1 for Pre-monsoon season and 7.0 to 7.7 for Post-monsoon season; conductivity 874 to 9138 mhos/cm for Premonsoon season and 786 8225 mhos/cm for wet season; total dissolved solids (TDS) 568 to 5940 mg/L for dry season and 511 to 5346 mg/L for Post-monsoon season; Fluoride 0.892 to 2.56 mg/L for Pre-monsoon season and 0.83 to 2.38 mg/L for Post-monsoon season. The values for other parameters were exceeding the BIS permissible limit for drinking water. Therefore, the water is highly contaminated & non potable.
