Background: Continuous expansion of potable water pollution sources is one of the main concerns of water suppliers, therefore measures such as water safety plan (WSP), have been taken into account to control these sources of pollution. The aim of this study was to identify probable risks and threatening hazards to drinking water quality in Lighvan village along with assessment of bank filtratio...

Contaminant hydrology is the study of processes that affect both ground and surface water pollution. It draws on the principles of hydrology and chemistry. Contaminant hydrology and water quality research seeks to understand the role of soil properties and hydrologic processes on ground and surface water pollution and develop strategies to mitigate their impacts. Research is done at all scales ...

Objective: The world is currently facing with various problems including water and soil pollution as well as a major threat to the health of the citizens due to the advancement at human civilization, technology development, pesticides and chemical fertilizers application, the increasing exploitation of natural resources by the agricultural s...

Undisturbed natural wetlands are important carbon sinks due to their low soil respiration. When compared with inland alpine wetlands, estuarine wetlands in densely populated areas are subjected to great pressure associated with environmental pollution. However, the effects of water pollution and eutrophication on soil respiration of estuarine and their mechanism have still not been thoroughly i...

environmental pollution consists of different types of pollutants in air, soil, and water. due to the fact that plants can respond to environmental pollution, they can be used as bio-indicators for environmental monitoring. air pollution in areas with oil and gas refineries nearby is an important problem. this study aims to survey the effects of gas refinery air pollutants on conocarpus erectus...

Understanding spatial and temporal variations in river water quality and quantitatively evaluating the trend of changes are important in order to study and efficiently manage water resources. In this study, an analysis of Water Pollution Index (WPI), Daniel Trend Test, Cluster Analysis and Discriminant Analysis are applied as an integrated approach to quantitatively explore the spatial and temp...
