From these data, an estimate of hydraulic conduc-tivity can be calculated using appropriate analytical methods (for example, Ferris and Knowles, 1963). A slug test requires a rapid (“instantaneous”) water-level Understand What You Are Testing An instantaneous change in head (slug) test is conducted in order to determine the hydraulic conductivity/transmissivity of a water-bearing zone in a quick and inexpensive manner. It can be conducted in materials of lower hydraulic conductivity than generally considered suitable for pumping tests. ASTM Standards. C1113 Test Method for Thermal Conductivity of Refractories by Hot Wire (Platinum Resistance Thermometer Technique) D2214 Test Method for Estimating the Thermal Conductivity of Leather with the Cenco-Fitch Apparatus.

D 4044 – 96. Standard Test Method (Field Procedure) for Instantaneous Change in Head (Slug) Tests for Determining Hydraulic Properties of Aquifiers. This report documents several spreadsheets that have been developed for the analysis of aquifer-pumping test and slug-test data. Each spreadsheet incorporates analytical solution (s) of the partial differential equation for ground-water flow to a well for a specific type of condition or aquifer.

This paper reviews four methods for analyzing slug test data to determine hydraulic conductivity and examines the effects of slug size on slug test results. Data from more than 100 slug tests, including tests for low permeability (glacial tills and fractured rock) deposits, coarse-grained (sand) deposits, and simulated tests were analyzed. 1.3 Limitations— Slug tests are considered to provide an estimate of transmissivity of a confined aquifer.

After many months of discussion (and shipping), I’m excited to introduce to you a series of premium quality shotgun slug moulds from another Russian manufacturer, ASM. Web System of Environmental Litigation Associates | Institute of References were updated, in particular, the references to ASTM standards and U.S. EPA guidance documents. Additional information has been added on: • obtained with the Geoprobe Systems® GW1600 Pneumatic Slug Test Kit. use of appropriate field methods to install and develop the well or sampler (ASTM. 16 Feb 2017 ASTM D4043-17 - Standard Guide for Selection of Aquifer Test Method in Determining Hydraulic Properties by Well Techniques and 31 Mar 2014 This webinar discusses using slug tests to evaluate an aquifer. Learn what slug tests are and why they are conducted, the differences between 14 Jan 2017 accordance with either ASTM D4044 or ASTM D7242. Following the initial slug test, the.

Most slug tests are conducted as single-well tests in which heads (displacements) are measured in just the test (control) well. In a multi-well slug test, heads are recorded in the test well and one or more nearby observation wells for subsequent analysis.

D 4044 – 96. Standard Test Method (Field Procedure) for Instantaneous Change in Head (Slug) Tests for Determining Hydraulic Properties of Aquifiers. Slug tests shall be conducted on relatively undisturbed wells. If a test is conducted on a well that has recently been pumped for water sampling purposes, the measured water level must be within 0.1 foot of the water level prior to sampling.
