5 Reasons to Use Eductor Systems for Complex Rehabilitation
Rehabilitation of dams and levees present complex geotechnical conditions. Contractors require dry, safe and stable working environments in order to carry out an effective rehabilitation project. As our national dam and levee infrastructure ages, the pressure to stabilize construction sites and lower costs will rise. Eductor systems provide a safe, cost-effective dewatering solution for these ...

Plume distortion and apparent attenuation due to concentration averaging in monitoring wells
This paper, authored by University of Connecticut researchers who performed much of the early work on this topic, describe the various processes that bias groundwater samples collected from conventional monitoring wells. In particular, they discuss the dilution of contaminants that occurs when clean water is simultaneously drawn into monitoring wells pumped to produce groundwater ...

Water Active: Borehole Management in Civil Engineering Projects
Groundwater wells are common to many civil engineering schemes and their operational performance can play a crucial role in the successful delivery of a project, whether used for construction dewatering, alternative water supplies for facilities or any other application , the well performance must be optimized and high levels of operational efficiency and service availability achieved. A ...

Bank filtration as managed surface-groundwater interaction
Riverbank Filtration (RBF) is a managed surface-groundwater interaction process where surface water is induced to flow to pumping wells installed on the banks of rivers and lakes. We present the surface-groundwater interaction issues at various geomorphologic settings, from the headwaters of a river to its confluence with the oceans/lakes. In each reach, the factors for the sustainable operation ...

Effective Groundwater Monitoring Using Dedicated Pumping Tubes
This article describes a groundwater monitoring procedure that does not require decontamination of pumping equipment, eliminates the chance of cross contamination between wells, and uses a surface pump. Two surface pumps are described, one for water level depths less than 25 feet and one for water level depths greater than 25 feet. Install Dedicated Pumping Tubes A dedicated pumping tube ...

MP 1 pump indispensable when measuring water quality - Case Study
Good surface and groundwater quality means sustainable development of plants, animals, and reliable drinking water. To guarantee this quality, a policy has been formulated in the Water Framework Directive which must be observed by all EU Member States. Due to the integration of various European water quality directives, the European countries are on the same page in terms of water-related issues, ...
