Recent increases in the use of hydraulic fracturing (HF) to aid extraction of oil and gas from black shales have raised concerns regarding potential environmental effects associated with predictions of upward migration of HF fluid and brine. Some rec

[1] The widespread use of hydraulic fracturing (HF) has raised concerns about potential upward migration of HF fluid and brine via induced fractures and faults. We developed a relationship that predicts maximum fracture height as a function of HF flu

Evapotranspiration (ET) can cause diel fluctuations in the elevation of the water table and the stage in adjacent streams. The diel fluctuations of water levels change head gradients throughout the day, causing specific discharge through near-stream

Groundwater that bypasses the riparian zone by travelling along deep flow paths may deliver high concentrations of fertilizer-derived NO3− to streams, or it may be impacted by the NO3− removal process of denitrification in streambed sediments. In

The effect of retention time on redox sequences along the hydrological flow path of groundwater discharging through low-relief coastal stream sediments and the subsequent impact on the fate of NO3 carried in the groundwater was examined in two intact
