Geetanjali Girls P.G. College, Bhopal - 462038 (INDIA) <p style="text-align: justify;">Water is the mirror of civilization since the origin of life. The increase in population coupled with unplanned urbanization and industrialization has resulted in damage and deterioration in ground water quality. Ground water is the most important source of water supply for irrigation, industries and for drinking purposes. Municipal and industrial sewage water when enters into an aquifer are the major sources of organic and inorganic pollutants. Trace elements in ground water within the limits may be useful but harmful when the value increases beyond the limits. Hence, the aim of present study is to assess the heavy metals seasonally concentration in the year 2003-04 by Atomic Absorption Spectrophotometer (AAS). Total iron, Cu, Mn, Zn, Ni &amp; Cr are analyzed and these trace elements has ranged. Cu has the range of 0.010 - 0.064, 0.01 1 - 0.040 and 0.005 - 0.068 ppm range of 0.010 - 0.061, 0.01 I - 0.040 and 0.005 - 0.06 S ppm in winter, summer and Monsoon Season respectively. Mn ranged from 0.030 -0.740, 0.023 - 0.31 5 and 0.020 - 0.700 ppm in W, S and M respectively, Zn element ranged I-1,0111 0.1 10 -0.910 ppm while Ni and Cr are in the range of 0.010 - 0.016 ppm and BDL in the present study.</p> https://journalofchemistry.org/paper/841/ trace-elments ground water
