Abstract
The groundwater of Gwalior region was assessed for its irrigational suitability. Fourteen water samples collected from dug-cum bored wells tapping shallow to deep aquifers from the clay with Kankar, silt, sandstone were used. The Groundwater samples were analyzed for major cations: Na + , Ca ++ , Mg ++ , K + ,and anions: Cl - ,HCO3 - , CO3 -- , SO4 - and NO3 - . The important constituents that influence the water quality for irrigation are total dissolved solids (TDS), electrical conductivity (EC), sodium adsorption ratio (RSC), sodium percentages (Na%) and permeability index (PI). These parameters were compared with standard limits and were found to be within the safe limit suitable for irrigation purpose. In addition the total dissolved solids in ground water ranged between 256-1324 mg/l during the investigation period, revealed that irrigation using groundwater of the study area would not cause salinity hazards.
Highlights
About 80% of the earth's surface is covered by water yet qualitatively 97% of this vast natural resource falls unfit for human use (Rai, 2004)
14 water samples of dug-cum bored wells were collected around Gwalior (M.P.) during pre monsoon period (April 2006)
The water samples were analyzed for major cations and anions such as Na+, Ca++, Mg++, K+, total dissolved solids (TDS), electrical conductivity (EC), total hardness
Summary
That in some areas the EC values increase with the Classification Total Dissolved Samples no. Increasing amounts of sulphate, carbonate, Non saline solids (mg/l) < 1000. (Study area) 1,2,4,5,6,7,8,9, Bicarbonate & Hardness as CaCo3.
