For groundwater and well assessments, it is important to obtain accurate water levels, including static water levels, to determine groundwater flow directions, groundwater flow velocities, seasonal variations in water levels, hydraulic conductivity, and other hydraulic characteristics of wells and aquifers. The above noted characteristics help determine if an aquifer can be used for a large taking astj if interference will result from a large dewatering project.
The Wells Regulation – Measuring of the static water level, or testing of the well yield, in a test hole or dewatering well is not required in any of the following situations:. The Wells Regulation – Before the structural stage of a test hole or dewatering well is complete, the person constructing the test hole or dewatering well must:.
Monitoring Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work.
It applies only to transducers characterized by their ability to transform, with the aid of an auxiliary energy source, a non-electric quantity to a process-relevant electrical signal, and to output the signal at one or more ports. A horizontal line is shown below the SWL but above the pressure transducer. As the voice of the U. A casing extends from above the ground surface into the subsurface. More information Permit to Take Water can be found on Ontario. The discharge water from a pumping test or other aquifer test must not cause an adverse effect to the natural environment and should not interfere with the test.
Two packer systems typically start testing at the bottom of a well and work upward.
Multi-level Monitoring Test Holes 9. I look at updates updates from the following ASTM comittees:. Subscription – always available and updated A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition.
Packer tests typically involve testing multiple zones in the well. The person constructing a test hole or dewatering well is exempt from performing a yield test if sstm static water level is measured as described below.
This asmt edition cancels and replaces the first edition published in Measuring Static Water Level Before the structural stage of a test hole or dewatering well is complete, the person constructing the test hole or dewatering well must: A horizontal line is shown in the subsurface above the top atm the pressure transducer.
An inflatable packer or packers are used to isolate a portion of the well. The benefits of a subscription: We have asrm amendments or corrections for this standard. Hydraulic conductivity is a function of both the formation through which a fluid is moving and the fluid itself.
Water Level Measurements, Aquifer Testing & Discharge Water Handling |
Typically, both vertical and horizontal hydraulic conductivity are calculated. If the document is revised or amended, you will be notified by email.
Standards Subsctiption may be the perfect solution. Field hydraulic conductivity tests are designed field experiments to determine how groundwater is flowing through a formation. A rope extends from the ground surface into the well. Proceed to Checkout Qstm Shopping. Test holes and dewatering wells – Requirements and best management practices 2.
Environment, Conservation and Parks. Webprint Printed and bound. This chapter discusses the reasons, procedures and methods for water level measurements in the well and aquifer testing.
ASTM Standards November Update
Need more than one copy? The measurements are used in calculations to interpret the hydraulic characteristics of aquifers and wells.
ASTM standards are an important part of my geotechnical engineering practice, and keeping up with changes can be a challenging thing. To obtain accurate data, the pumping rate during the test should be accurately measured and recorded. A datalogger is shown to the right of the well on top of the ground surface.
The measurement methods are broken into the following two groups:. A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. The requirements for the Wells Regulation on measuring and reporting water levels in test holes and dewatering wells are also provided.
This ensures that you are always up-to-date and saves you both time and money. Before the structural stage of a test hole or dewatering well is complete, the person constructing the test hole or dewatering well must:. This standard is also available to be included in Standards Subscriptions.
