Sambhar Salt Lake a Hydrochemical Approach- Archana Gaur

Abstract

Sambhar salt lake, is an Athalassic and endorheic lake and is always changing. Water spread Area, depth, temperature and hyo-chemical conditions vary with season and year to year. Shoreline of the lake shifts amatically as it lies in a broad and relatively flat basin. The present work focuses on the hyo-chemical study carried out during 2013. Total rainfall during the period was 348 mm. Average Temperature variations were from 7 to 37a�C. , pH 6. 54 to 8. 87, water Density 3-25 Be, Alkalinity Nil-2670 mg/L, Hardness from 28- 115 mg/L, Salinity 0. 53-162. 21 % and Dissolved oxygen from Nil-3. 6mg/L. Total anoxic condition prevailed during most of the months while Free Carbon di-oxide was recorded only once during July-13 value being 25 ppm. Nutrient were in low concentration as itrate and Phosphate fluctuated between 1. 16 -7. 21 ?g / L and 1. 9-8. 94 ?g / L. aCl content in lake brine was 98. 67% in Jan-13 while post monsoon the values low
