Slug tests are ideal for determining the hydraulic parameters for wells ranging from 2- to 6-inch diameter in low to medium permeability formations (e g , can be pumped or bailed dry), and for determining the spatial variations in hydraulic parameters across a monitoring well field (i e , aquifer
- Slug Tests :. Aquifer Testing 101 - AQTESOLV
Slug tests are frequently designated as rising-head or falling-head tests to describe the direction of water-level recovery in the control well following test initiation Other terms sometimes used instead of slug test include baildown test, slug-in test and slug-out test
- Pumping and Slug Tests - Cloudinary
If slug tests are used, the designer should consider the amount of displaced water, design of the well, number of tests, method and frequency of water level measurements, and the method used to analyze the data Slug tests should be conducted in properly designed and developed wells or piezometers If development is
- GWPD 17—Conducting an Instantaneous Change in Head (Slug) Test with a . . .
During a slug test the water level in a well is changed rapidly, and the rate of water-level response to that change is measured From these data, an estimate of hydraulic conduc-tivity can be calculated using appropriate analytical methods (for example, Ferris and Knowles, 1963)
- SLUG TESTS #2046 - Rhode Island
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 The primary advantages of using slug tests to estimate hydraulic conductivities
- Field Pneumatic Slug (Instantaneous Change in Head) Tests to Determine . . .
taneous change in head (slug) test when pneumatic pressure is used to initiate the change in head pressure within the well or piezometer While this practice specifically addresses use of pneumatic initiation of slug tes
- Conducting an Aquifer Slug Test - Envirotech Online
Before performing a slug test, the following field equipment is required: water level instrument with rapid or true logarithmic measurement capabilities, software for analysing data and modeling results, water level tape, personal protective equipment, and a slug
