Environmental drilling in action

A Basic Explanation of Environmental Drilling

There are many people who wonder what environmental drilling is and what it can be used for. It is important that you understand what this kind of drilling is and whether there are any applications that suit your needs. It is important to note that environmental drilling is not something that everyone will have a need for.

What Is Environmental Drilling?

Before you start looking at the applications of environmental drilling, you need to know what this is. Environmental drilling is a service which is performed to take groundwater or soil samples. These samples are generally required to determine if there is contamination to the area or if monitoring or remediation wells are required to treat the groundwater. There are a number of different drilling and probing techniques which are used as part of environmental drilling.

The first is sonic drilling which uses a rotary and vibratory drilling system. This system is generally used for sampling up to a depth of 200 meters and will generally work to core overburden or friable rock formations. The core overburden could be gravel, earth, sand or cobbles.

Hollow-stem auger drilling will use flight-style augers with a hollow center. These drills can be used up to a depth of 60 meters. The samples that these drills obtain come from periodically driving a hollow spoon down the hollow inside of the drill.

The last type of drilling that you should know about is direct-push drilling. This drilling is also known as soil probing and is a basic form of sampling. A hollow sample tube will be driven into the ground by a high-speed hammer. This form of sampling can be used up to a depth of 50 meters.

Applications Of Environmental Drilling

There are many applications of environmental drilling that you should be aware of. These applications are generally divided into 2 categories of investigation and remedial. The application of the drilling will impact the type of drilling system that is used.

One of the common applications of environmental drilling is for groundwater monitoring wells. This application will have the drills creating a borehole where monitoring wells can be placed. Each of the monitoring wells will look for contaminants in the groundwater and will be at varying depths. The borehole will generally be sealed after the drilling to ensure that there is no cross contamination of the samples.

Another application of this drilling to create extraction wells. These wells will generally be used to treat groundwater that has been contaminated. The water will be pumped out of the well and then treated for the contaminant. The water will then be pumped back into the well and the well will be sealed to prevent any further contamination.

It is important that you know what environmental drilling is and what its applications are. This will help you determine if you need to hire the services of an environmental drilling professional. Generally, environmental drilling is used by farmers and those who use groundwater.
