Deep groundwater aquifers are poorly characterized but could yield important sources of water in California and elsewhere. Deep aquifers have been developed for oil and gas extraction, and this activity has created both valuable data and risks to groundwater quality. Assessing groundwater quantity and quality requires baseline data and a monitoring framework for evaluating impacts. We analyze 9...

introduction the chemical characteristic of groundwater as a major source of water supply for human life is an important factor in determining the usage of it for agriculture, industry and drinking. useful techniques and different methods of studying the chemical composition of groundwater such as correlation coefficient, descriptive statistics, factor analysis and cluster analysis provide an u...

In the context of the Water Framework Directive, management plans have to be set up about water quality issues in surface and ground water bodies in the EU. In heavily industrialised and urbanised areas, the cumulative effect of multiple contaminant sources is likely to present a risk which has to be evaluated. In order to propose adequate measures, the calculated risk should be based on criter...

Introduction Conclusions References

background: one issue of concern in water supply is the quality of water. measuring the qualitative parameters of water is time-consuming and costly. predicting these parameters using various models leads to a reduction in related expenses and the presentation of overall and comprehensive statistics for water resource management. methods: the present study used an artificial neural network (ann...

background: iran is located within the dry and semi dry regions, thus almost 90% of the required water is secured via the use of groundwater. owing to the increasing pollution of water resources, this study was performed to evaluate water quality pollution indices for heavy metals (as, zn, pb and cu) contamination monitoring in toyserkan plain during spring and summer in 2012. methods: a total ...

the objective of this study was to classify the shoosh aquifer to several zones with different water quality in khuzestan province, iran. in this regard, the performance of classification methods (discriminant function and cluster analysis) for the classification of groundwater based on the level of pollution with an emphasis on the problem of over-fitting in training data were considered. an o...

The rapid growth in the world population resulted an increase of freshwater needs many sectors. Groundwater is most important source specially for arid and semi-arid regions due to lack surface water sources low precipitation rates those regions. In this study, monthly groundwater quality data were collected from eleven well fields Sharjah over period 2004-2017. Water parameters including bicar...
