What is a baildown test?
Baildown testing is one method to measure LNAPL transmissivity. Detailed procedures to conduct and analyze baildown testing are provided in ASTM E-2856(2013). API sponsored development of this short (14 minute) training video discussing procedures to conduct a successful baildown test for unconfined LNAPL.
How do you do a slug test?
Types Of Slug Tests
- A rising-head test is initiated by rapidly lowering the water level in the control well and then taking measurements of the rising water level in the well.
- A falling-head test is conducted by rapidly raising the water level in the control well and subsequently measuring the falling water level.
What does a slug test measure?
A slug test involves the instantaneous injection or withdrawal of a volume or slug of water or solid cylinder of known volume. This is accomplished by displacing a known volume of water from a well and measuring the artificial fluctuation of the groundwater level.
What is the purpose of slug test?
What is the difference between slug test and pump test?
In a pumping test, a pumping well stresses an aquifer by extracting or injecting water at a controlled rate. In a slug test, the imposed hydraulic stress is due to a sudden change in water level in the control well.
What is the purpose of pumping test?
The goal of a pumping test, as in any aquifer test, is to estimate hydraulic properties of an aquifer system. For the pumped aquifer, one seeks to determine transmissivity, hydraulic conductivity (horizontal and vertical) and storativity (storage coefficient).
What is the SI unit of hydraulic conductivity?
The joule per kilogram (J/kg) is suggested as the preferred unit for describing water potential, and hydraulic conductivity then has units of kg s m-a.
What are types of pump test?
There are two general types of pumping tests: (1) step drawdown tests and (2) constant rate tests.
What is hydraulic conductivity used for?
Hydrologists need hydraulic conductivity values for modeling, and researchers use it to determine soil health or to predict how water will flow through soil at different field sites. Agricultural decisions are based on hydraulic conductivity for determining irrigation rates or to predict erosion or nutrient leaching.
What is the purpose of a pump test?
What is pump performance test?
A pump test is a procedure carried out by a pump manufacturer, supplier, installer, or owner to confirm one or more aspects of pump design or performance. Pump tests are conducted to confirm that the pump meets the performance, design, and construction standards required by the project specifications and data sheets.
How is pumping test done?
A pumping test is a field experiment in which a well is pumped at a controlled rate and water-level response (drawdown) is measured in one or more surrounding observation wells and optionally in the pumped well (control well) itself; response data from pumping tests are used to estimate the hydraulic properties of …
What are the type test of pumps?
The NPSH test, mechanical running test, and final inspection are done after performance test. The vibration testing is carried out during performance test and mechanical running test. You may also want to review a general centrifugal pump inspection and test procedure.
Why is pumping test done?
Pumping Tests are conducted to examine the aquifer response, under controlled conditions, to the abstraction of water. Hydrogeologists determine the hydraulic characteristics of water-bearing formations, by conducting pumping tests.
