Kadam 2 Naveen Kumar Singh 2 Department of Chemistry, S.M.S., Govt., Model Science College, Gwalior M.P. - 474002 (INDIA) Division Ground Water Survey, Gwalior (M.P.) INDIA <p style="text-align: justify;">The quality of ground water depends on the ion, which are dissolved in ground water. The major ions which are responsible to maintain the quality of ground water are carbonate (CO32-.) and bicarbonate(HCO3-1), Chloride (Cl-1), sulphate (SO4-2), nitrate (NO3-1), phosphate (PO4-3), fluoride (F-1). These ions are present in anionic form. The cation and anion must be equal to maintain the quality of water cation such as Ca2+, Mg2+,Na+ and K+ are also present in ground water in form of hardness and salinity. 10 water samples are collected from Narwar Block (Shivpuri District) for post mansoon season (2004). The ionic concentration is expressed in mg/L.<br /> &nbsp;</p> https://ultraphysicalsciences.org/paper/1359/ pH Total alkality Total hardness calcium hardness Magnesium hardness Na+
