The solution was found in the Laplace domain and type curves were obtained by numerical inversion. Using realistic values of aquifer and skin hydraulic properties, we show the effects Of a finite- INTRODUCTION The slug test is known to be a valuable Describes how to use the slug test data sheet with some suggestions about conducting slug tests ASTM-E457 › Historical Revision Information Standard Test Method for Measuring Heat-Transfer Rate Using a Thermal Capacitance (Slug) Calorimeter ASTM-E457 - 2008 EDITION - SUPERSEDED Show Complete Document History The video is to demonstrate a well test type - Slug Test. The test planning is considered while performing pressure transient analysis in Gintel Plog Softwar ASTM D4104-96 Standard Test Method (Analytical Procedure) for Determining Transmissivity of Nonleaky Confined Aquifers by Overdamped Well Response to Instantaneous Change in Head (Slug Tests) SLUG TESTING FOR SITE CHARACTERIZATION: Practical Guidelines for Processing and Analysis of Your Slug Test Data. Despite slug tests being the most common technique for determining transmissive properties at sites with ground water contamination, much of the information is of questionable quality as a result of inappropriate field and analysis procedures.

2.0 Required Equipment All the components of the Pneumatic Slug Test kit are provided in a carrying case for ease of transportation. [2] Slug tests are used to characterize the hydraulic conductivity and storage properties of the subsurface. While the natural subsurface is always heterogeneous to some degree, slug-test data are usually interpreted with simple analytic models that contain spatially homogeneous param-eters. The objective of this work is to investigate how A slug test involves inducing a rapid change in water level in a test well (see note: slug). By measuring and recording the rate of return to static conditions (recovery), one is able to estimate the local horizontal hydraulic conductivity of the material surrounding the well. Refer to the following guidance documents when conducting slug tests using the MidwestGeo PNEUMATIC HI-K SLUG®: ASTM D7242 - 06 Standard Practice for Field Pneumatic Slug (Instantaneous Change in Head) Tests to Determine Hydraulic Properties of Aquifers with Direct Push Ground Water Samplers http://www.astm.org/Standards/D7242.htm In-Situ, Inc. Technical Note Pneumatic Slug Testing on Highly Transmissive Aquifers http://www.in-situ.com/Technical_notes This method was originally published in an article entitled "Slug Test Procedure to Evaluate Hydraulic Conductivity of an Aquifer Applicable to Fully or Partially Penetrating Wells in Unconfined Aquifers".
