Source water protection in areas of shale gas development encompasses identifying that are the most vulnerable to groundwater quality deterioration due spills natural production wastewater. This study uses density-dependent flow and transport code TOUGH2 quantify time distance travel saline wastewater plumes for different hydrogeological settings Northeast British Columbia. The models were desi...

Thus, groundwater can be easily susceptible to infiltration from dumpsites, septic tanks and other anthropogenic activities. Approximately, one fifth of the world total freshw...

Coastal aquifers are increasingly threatened by seawater intrusion due to increased urbanization, groundwater exploitation, and global sea-level rise. Pattern diagrams, which constitute the outcome of several hydro-geochemical processes, have traditionally been used to characterize vulnerability to seawater intrusion. However, the formats of such diagrams do not facilitate the geospatial analys...

A geochemical study was conducted to obtain a comprehensive understanding of fluoride concentration increase in groundwater from a crystalline (hard-rock) aquifer in a small Indian agricultural watershed, where groundwater is intensively abstracted for paddy irrigation. A reactive1-D geochemical model using PHREEQC was used to reproduce fluoride concentrations under rice paddies taking into acc...

Analyses of areal variations in the subsidence and rebound occurring over stressed aquifer systems, in conjunction with measurements of the hydraulic head fluctuations causing these displacements, can yield valuable information about the compressibility and storage properties of the aquifer system. Historically, stress-strain relationships have been derived from paired extensometer/piezometer i...
