, standpipes and tanks. The drawdown function is used to monitor falling hydraulic head during low flow sampling, pumping and other aquifer/well tests. It also ensures a pump’s intake remains submerged during purging or well ...
The Solinst Double Valve Pump (DVP) is a pneumatic drive pump that allows consistent, high quality samples. It has been field proven in thousands of applications. ...
Roscoe Moss Company Technical Memorandum 009-3 Pumping Tests: Production and Efficiency Determinations Introduction Pumping tests provide very useful information that is needed to properly select pumping equipment, assess aquifer conditions, and evaluate well performance. Truth be told, the importance of ...
The word “Verification”, when used in connection with computer software can be defined as “the ability of the computer code to provide a solution consistent with the physics defined by the governing partial differential equation, PDE”. There are also other factors such as initial conditions, boundary conditions, and control variables that also affect the accuracy of the ...
High Definition Data Logging: The 16 Bit Resolution inherent in Dynotek’s Data Manager improves overall accuracy of measurements by providing substantially better resolution of readings regardless of the underlying accuracy of the sensor input. Analog sensors are essentially continuous in output, with infinite resolution possible. In converting the data from analog to digital, much of the ...

. An increased amount of reaction products may migrate into the aquifer and a longer pumping time will be necessary to remove them.Any significant migration of the working solution into the aquifer can be observed by monitoring the pH-value and the specific electrical conductivity of the solution during the reaction time of ...
discharge of the working solution into the aquifer and to optimise the effectiveness of the process, the working solution should be kept in motion by means of a circulation pump. After its application onto any one section of the well, the process of removing the incrustations is completed within 60 minutes. Leaving the ...
The goal of the NanoRem project is to show that the application of NPs is a practical and reliable method for the treatment of contaminated soil and groundwater. NanoRem will provide a direct link between the production side and application of groundwater remediation using NPs. NanoRem is exploring the use of two broad classes of NPs, nano zero valent iron (nZVI) and others including iron oxides ...
