What does a slug test measure?

A slug test is a controlled field experiment performed by groundwater hydrologists to estimate the hydraulic properties of aquifers and aquitards in which the water level in a control well is caused to change suddenly (rise or fall) and the subsequent water-level response (displacement or change from static) is …

What is the packer test?

Packer testing is a technique in which one or more inflatable bladders, or packers, are used to isolate different regions of a borehole for hydraulic testing or water sampling.

What is a step drawdown test?

A Step-Drawdown Test is an accelerated pumping test for a single well, designed to estimate the aquifer characteristics and performance of a pumped well under three successively higher pumping rates or steps under controlled flow. The test is suitable for a design production rate of 35 gallons per minute (gpm) or less.

What is Slug water?

A slug test is a particular type of aquifer test where water is quickly added or removed from a groundwater well, and the change in hydraulic head is monitored through time, to determine the near-well aquifer characteristics.

Which test is performed after the pump inspection?

Which test is performed after the pump inspection? Explanation: After the inspection, the pump casing hydrostatic test is performed. It takes place only after successful completion of the pump casing inspection. Explanation: The pump hydrostatic test is tested at 1.5 times the maximum allowable work pressure.

Which has the highest hydraulic conductivity?

Because of their high porosity and permeability, sand and gravel aquifers have higher hydraulic conductivity than clay or unfractured granite aquifers.

What is meant by hydraulic conductivity?

Hydraulic conductivity is a physical property which measures the ability of the material to transmit fluid through pore spaces and fractures in the presence of an applied hydraulic gradient.

What is falling head permeability test?

The falling head permeability test is a common laboratory testing method used to determine the permeability of fine grained soils with intermediate and low permeability such as silts and clays. This testing method can be applied to an undisturbed sample.

What is the purpose of step drawdown test?

A step-drawdown test (or step test) is a single-well pumping test designed to investigate the performance of a pumping well under controlled variable discharge conditions.
