This research aims to assess the hydrogeochemical evolution and assessment for drinking irrigation use of spring water from alluvial aquifer major karst systems in Tebessa (the northeastern part Algeria). For achieving this goal, 25 groundwater samples several springs, including thermo-mineral were examined subjected multivariate statistical analysis (principal component analysis), isotopic app...

spatiality assessment of groundwater pollution is very important to determine water quality condition, pollution sources and management decisions. in this case, gis and geostatistics methods can be useful tools. spatiality of groundwater quality parameters, in relation with various land uses, can be very extremely. therefore water samples from 52 wells in the kurdan area were analyzed in this s...

We investigate a rst-order extension of the Theory of Primitive Objects of 5] that supports method extension in presence of object subsumption. Extension is the ability of modifying the behavior of an object by adding new methods (and inheriting the existing ones). Object subsumption allows to use objects with a bigger interface in a context expecting another object with a smaller interface. Th...

Water quality is a key environmental issue concerning the agricultural sector. Here, the application of fuzzy set theory for decision-making in the assessment of groundwater quality for agricultural purposes is being discussed. The experiments conducted in this study area located, Shahrekord plain that, lies in the Chaharmahal and Bakhtiari province, in the southwest Iran. Four groundwater para...

Groundwater is an important, but undervalued, national resource in Scotland. Groundwater is present both in the bedrock, where much of the flow is through fractures, and in the superficial deposits, where intergranular flow dominates. The most productive bedrock aquifers are the Permian sandstones and breccia in SW Scotland and the Devonian sandstones in Fife, Strathmore and Morayshire. Alluviu...

A new way of thinking about groundwater age is changing the field of groundwater age dating. Following a rigorous definition of age, a groundwater sample is seen not as water that recharged the flow regime at a point in the past, but as a mixture of waters that have resided in the subsurface for varying lengths of time. This recognition resolves longstanding inconsistencies encountered in age d...

Abstract The Bathinda district of Punjab, India has been reported with the highest per capita number cancer patients. Groundwater is major source drinking and irrigation in district. hydrogeochemical analysis indicated Na-HCO3 Na-SO4/Cl type water district, rock-water interaction return flow influenced cations. Only 10% samples were very poor category for purposes, which increased to 95% post-m...
