The Krishni-Yamuna is a watershed in the most productive central Ganga plain. Systematic sampling was carried out in Krishni-Yamuna Basin in parts of Muzaffarnagar district, with a view to understand the sources of dissolved ions and to assess the quality of groundwater. Forty samples were collected from handpumps, covering an area of 434 square km. The quality of groundwater is suitable for irrigation purposes. As far as human consumption is concerned, the quality has a negative aspect in being SO4-enriched. Na+K and Cl+SO4 are dominating facies in cations and anions respectively. Based on chemical characteristics, the groundwaters have been divided into four groups. Group I and group II samples have acquired their chemistry through sediment-Water interaction and dissolution mechanism. Group III and IV samples depict an increasing influence of anthropogenic factors.Keywords

Central Saudi Arabia is one of the most arid regions of the world with very little precipitation and extreme climatic conditions. In the absence of available surface water supplies, the non-renewable groundwater resources stored in the Palaeozoic and Mesozoic sedimentary formations form the most important source for irrigation and domestic water requirements. The present study deals with 97 groundwater samples collected from Saq aquifer, which is the major aquifer in the region. The study involves the use of principal component analysis (PCA) and variogram analysis for groundwater quality mapping. PCA helped in establishing a series of factorial variables that summarize all the hydrochemical information. Efforts have been made to identify the spatial development of the principal process acting on groundwater quality by mapping it using factorial variables and ordinary kriging techniques. Two principal components (PCs) were extracted revealing that the chemical characteristics of groundwater in the region were acquired through rock-water interactions and anthropogenic influences. Finally, by applying kriging interpolation technique on the factor distribution values for the two PCs in the area under investigation, the factor distribution maps were prepared. The results concluded that both natural and anthropogenic processes contribute to the groundwater quality, but anthropogenic impacts are more important and may result in further deterioration of groundwater quality if relevant protection methodologies are not adopted.Keywords
