The groundwater quality was assessed nearby places of Nagalkeni, Chennai, Tamil Nadu, India. The selected physico-chemical parameters were pH, EC, TDS, total hardness (TH), anions like Ca, Mg, Na and K, and cations like SO4, NO3, Cl2, HCO3, and CO3, and Cr(VI). In order to suit the groundwater for drinking and irrigation purposes, compared the value of selected parameters with the value of sele...

The activity concentration for various radionuclides produced in the soil around the collimation section of the Beam Delivery System for the Next Linear Collider is calculated using the FLUKA Monte Carlo code. Different methods are used to calculate the activity concentration of H, Na and Be in soil. The activity concentration of H and Na in groundwater are also calculated and compared with the...

Differences in the impact of irrigation with freshwater versus wastewater on the underlying shallow groundwater quality were investigated in the Coastal Aquifer of Israel. Seven research boreholes were drilled to the top-most 3–5 m of the saturated zone (the water table region-WTR) in the agricultural fields. The unsaturated zone and the WTR below the irrigated fields consist mainly of clayey s...

Determination of groundwater chemistry in the Strumica valley was essential given its widespread use for irrigation in the agricultural industry. 224 samples were collected form boreholes forming the dataset for the study. The groundwater chemical composition was examined for selected analytes: As, Sr, Mn, Ni, Cu, Zn, Mo, Ba, Pb, Na, Mg, Al, K, Ca, Ti, Li, Cr, Fe, U, CaCO3, Cl-, NO3, NH4, SO4 a...

Determination of water quality is an essential issue in water resources management and its monitoring and zoning should be considered as an important principle in planning. In this study, in order to investigate the quality of groundwater resources (springs, wells and qanats) in Semnan watershed, first, the water quality index for drinking and agricultural purposes was obtained by means of meas...

Groundwater resource is vital for industrial, drinking and irrigation purposes in the Dagujia river basin, China. The objective of this work was to comprehensively assess hydrochemical characteristics evolution processes Quaternary aquifer (QA) bedrock (BA) basin using statistical methods plots. In total, 56 groundwater samples were collected from QA (34 samples) BA (22 samples). addition, comb...

Groundwater quality evaluation is very necessary to provide drinking water. Groundwater excessive consumption can cause subsidence and penetration of saline groundwater into freshwater aquifers in Ajabshir Plain, on the Urmia lake margin. The main goal of the current project was to evaluate the groundwater quality by employing the qualitative indices of groundwater and GIS. Ten parameters of 15...

as far as bandura’s (1977) conceptualization of the sense of self-efficacy is concerned, it is argued to be context- and even task-specific, compared to other concepts like self-esteem (brown, 2000); therefore, upon the previous research studies, related theories and definitions, and the ideas and views obtained from the interviews conducted with the scholars, the current research study aimed a...
