BACKGROUND Up to 150 million North Americans currently use a groundwater system as their principal drinking water source. These systems are a potential source of exposure to enteric pathogens, contributing to the burden of waterborne disease. Waterborne disease outbreaks have been associated with US and Canadian groundwater systems over the past two decades. However, to date, this literature ha...

rise of groundwater levels in unconfined aquifers can cause dryland salinity to increase by several processes including; dissolution of windblown halite, and incorporation of saline clay pore water. The primary process of increased groundwater salinity is evaporation of shallow groundwater as it rises to within a few meters of the ground surface. in murray Basin, australia, the effect of drylan...

Interactions between groundwater and surface water play a fundamental role in the functioning of riparian ecosystems. In the context of sustainable river basin management it is crucial to understand and quantify exchange processes between groundwater and surface water. Numerous well-known methods exist for parameter estimation and process identification in aquifers and surface waters. Only in r...

Leachate and groundwater samples were collected from Gazipur landfill-site and its adjacent area to study the possible impact of leachate percolation on groundwater quality. Concentration of various physico-chemical parameters including heavy metal (Cd, Cr, Cu, Fe, Ni, Pb and Zn) and microbiological parameters (total coliform (TC) and faecal coliform (FC)) were determined in groundwater and lea...

Leachate and groundwater samples were collected from Vendipalayam, Semur and Vairapalayam landfill sites in Erode city, Tamil Nadu, India, to study the possible impact of leachate percolation on groundwater quality. Concentrations of various physicochemical parameters including heavy metals (Cd, Cr, Cu, Fe, Ni, Pb, Fe and Zn) were determined in leachate samples and are reported. The concentrati...

groundwater quality in nour coastal plain in mazandaran province of iran is assessed by measuring physicochemical parameters including total dissolved solid, electrical conductivity, ph, total hardness, major cation and anion compositions and nitrate pollution. for this purpose, fifty groundwater samples were collected in july 2012. the hydrochemical types, ca–hco3 and mg–hco3 dominate in all s...
