The Slug Test Method is one of a number of different methods that are used to evaluate the permeability (or hydraulic conductivity) of an aquifer. The procedure involves either adding or removi ng a measured quantity of water from a well rapidly, followed by making a rapid series of water-level measurements to assess the rate of water-level recovery (either rising-head or falling-head).


12 Jul 2020 If the hollow point projectile (slug or pellet) increases in diameter, Take the test results with a grain of salt (or a 22-grainer of lead if you like).

Slug Test Field QC : Visual Check Three slug tests with ~same Ho (e.g. 2ft) • Compare peak height • Curve symmetry • Recovery time same length, pump pressure, and time of test period. However, as the parameter occurs within a natural. Darcian flow effects in slug tests conducted in fractured. rock boreholes. J Hydrol 486:505 Prior to each slug test, the equipment which was used for logging the water pressure heads during the tests (Van Essen Instrument Diver®) was exposed to air pressure and undisturbed water pressure. 2.2.3 Tests The performed slug tests are summarized in Table 2-2.

2.2.3 Tests The performed slug tests are summarized in Table 2-2. Table 2‑1. Technical data of the groundwater monitoring wells. The slug test data provided estimates of the hydraulic conductivity of the aquifer immediately adjacent to the boreholes. Pump tests were conducted using downgradient wells in high-hydraulic conductivity zones (based on slug tests) to determine their areas of influence. The tests were analyzed to determine hydraulic conductivity. The Pneumatic Hi-K Slug is very easy to use, with easy to follow instructions and a complete equipment check list.

The bailer test combines the speed and simplicity of the slug test, with the slow accurately recorded, or give an approximately steady pumping rate using bails.

For both kinds of 50 hydraulic tests, water level response is measured in one or more surrounding observation wells A slug test is in contrast to standard aquifer tests, which typically involve pumping a well at a constant flowrate, and monitoring the response of the aquifer in nearby monitoring wells. Often slug tests are performed instead of a constant rate test, because: time constraints (quick results, or results for a large number of wells, are needed), Slug test results compared favorably, with geometric mean hydraulic conductivity estimates of 4.9 · 10‐7 cm/s from a Cooper et al. (1967) analysis and 7.1 · 10‐7 cm/s from a Hvorslev (1951) analysis. For this relatively low clay till (20% clay fraction), borehole smearing does not appear to have a significant impact on slug tests. The purpose of this test is to determine if a vision based system can detect a water slug within kerosene or jet fuel. Sample Description 50/50 mix of kerosene and water Figure 1 – Sample description Typical Images Figure 2 - Steady state before valve is opened.

This is often used in geotechnical or engineering settings to get a quick estimate (minutes instead of days) of the aquifer properties immediately around the well.
