ANSWER ... geology is the main factor that determines the kind of drilling
equipment that should be utilized on a location.
The hollow-stem auger technique that is frequently used to monitor well
installations... An auger head that can be cut to highlight a plate that makes well
installation below ground water level easier should be included.
What does a monitoring well rig NOT include? ANSWER : Mud pump.
What is the smallest hollow-stem auger, casing, or borehole required to install a
standard 2-inch well? The response 4.25 in.
What is the most effective drilling technique that would result in the least
amount of fluid management in a highly hazardous polluted limestone
formation? ANSWER Cable instrument
In order to assess ground water contamination, monitoring wells are frequently
placed downstream of a landfill.
Out of the following, which one is not impermeable? ANSWER Sand
Because of the latest technological advancements, the monitoring tools and
supplies used today... ANSWER ...
The definition of glacial drift is... Glaciers carry unconsolidated silt, which is
then dumped directly onto land or the ocean.
For a seal above the filter packs, what kind of substance or materials are usually
found on monitor wells? The response Pellets of bentonite.
Drilling a bedrock monitoring well with an air rotary and a down-hole hammer
would be the most effective way.
, A hollow-stem auger's flight OD and ID often varied by four to five inches.
A hollow-stem auger drill rig's operational safety is jeopardized when... -
ANSWER ... drilling operations take place within 100 feet of an electrical wire.
Drilling equipment should be inspected every day for the following reasons,
among others. The response examination of the hoses, cables, etc.
Every fluid level
A first aid kit is accessible.
When drilling a monitoring well, the technique should... - ANSWER ... reduce
the amount of subsurface material disturbance.
When extracting the augers from the borehole, the "auger fork" prevents them
from "sliding" back into the hole by slipping through the flights of the auger
column.
The area on the site that may be contaminated and where personnel are required
to wear personal protective equipment (PPE) in accordance with the site-
specific health and safety plan is known as the exclusion zone for drilling
activities at a hazardous waste site.
One benefit of hollow-stem augers is that they don't require drilling fluid, which
means that drilling fluid additive contamination is avoided.
One drawback of employing cable tool drilling for well monitoring is...
ANSWER ... potential issues with managing heaving sands.
One possible cause of air in a recovery well system's discharge line is... The
response Drop pipe hole
Water cascading
Screen plugging and cavitation
A high pH could be a sign of contamination from cement grout seeping into the
filter pack.
Decontamination is carried out before departing a hazardous waste site to
ensure that no contamination escapes the site.
After drilling below the water table, how do you get rid of sand that has gotten
inside the hollow-stem auger? The response Use water that has been approved
to remove the sand.
