WellsGroundwaterDistribution SystemsTasteIndianaChemicalsSulfurOdorWater QualityThis article discusses how data from a groundwater well's profile can be used to modify the well so that raw water with undesireable chemical qualities is prevented from entering the well. A case study is presented of ...
Groundwater governance can be defined as the system of formal and informal rules, rule-making systems and actor networks at all levels of society that are set up to steer societies towards the control, protection and socially acceptable utilization of gr
1), known to contain hundreds of groundwater-fed springs, seeps, and stream resources. Environmental age tracers (tritium and carbon-14) and dissolved noble gases (He, Ne, Ar, Xe, Kr) from 12 springs and 2 wells are used to characterize groundwater age and recharge source(s). Age ...
Combined recharge: A method to prevent ground settlement induced by redevelopment of recharge wells 2019, Journal of Hydrology Citation Excerpt : If the groundwater in a confined aquifer cannot be reasonably controlled during excavation, large deformations and hydraulic heave will occur (Pujades et al...
wells, and is withdrawn under vacuum from the withdrawal well whereupon contaminants are removed from the air stream and the air is then recycled through the system. The U.S. Pat. No. 4,588,506, to Raymond et al., discloses the injection of a diluted solution of hydrogen peroxide into ...
1 for location of wells), and precipitation datasets. We compare and analyze the estimates of GWS changes in subperiods from GRACE with the in-situ GW-level measurements and literature results, depict the land surface deformation at 22 sites, and conduct analysis of precipitation impacts on GWS...
Figure 6 shows observations of bedrock outcrops, boreholes with bedrock levels and clay thickness, groundwater observation wells, pump tests (Martinsson et al. 2016) and piston samples of clay (Hurtig et al. 2016; Trafikverket 2016). The borehole and groundwater head data is collected from...
The appeared depression funnels cause tightening of the additional volume of river run-off to the groundwater intake wells, that is damage river r run-off. Given volume of the river run-off must not be calculated twice when assessing the common water balance of the region. Opposite situation ...
