Many people would like to know exactly what environmental drilling in Edmonton is and its application and benefits. It is vital for you to understand the meaning and use of this type of drilling if you are responsible for monitoring the underground water and soil for pollution and contamination. It is also important for homeowners and business people who want to install their own wells and bore holes for water supply or in their residence or business premises, and those who need a water filtration system in Edmonton.
What is Environmental Drilling in Edmonton?
Environmental drilling is a specialized service that is performed to take soil and under ground water samples. The samples are obtained to determine whether there is significant contamination in the area. They may also be used to know if a water filtration system in Edmonton can be used to remedy the situation and ensure that all water from private wells and boreholes will be fit for drinking.
A number of techniques are used during environmental drilling in Edmonton. One is sonic drilling. This method involves the use of a vibratory and rotary drilling technique. Sonic drilling allows for sampling to a depth of 200 meters below the earth’s surface and it can reach core rock formations including sand, earth, gravel or cobbles.
Other types of drilling used for environmental drilling include the hollow-stem auger drilling method. It is suitable for drilling to a 60-meter depth. The samples in hollow stem drilling are obtained periodically by pushing a hollow spoon into the hollow section of the drill. Another well-known method used for this kind of drilling is the direct-push drilling. It is also called soil probing. The operator drives one hollow sample tube into the earth with a high speed hammer. This type of drilling can only be used to take samples from a maximum depth of 50 meters.
Environmental Drilling Applications
Underground Monitoring Wells: Environmental drilling is an effective way to drill groundwater monitoring wells. After drilling, a borehole will be created for the installation of the monitoring wells. Each monitoring well will serve as a place for sampling for contaminants at different depths below the earth’s surface. After the drilling, the borehole will be sealed to prevent contamination between samples from each well.
Groundwater Filtration: When there is a need to treat water that has been contaminated, environmental drilling techniques may be used to set up a water filtration system in Edmonton. Water will be pumped out from the extraction well and treated to eliminate the contaminant. The water will be pumped back into the well and sealed up to avoid future contamination.
Benefits of Environmental Drilling
The benefits of environmental drilling far outweigh the costs. For instance, sonic rigs are lighter, smaller and faster to drill than conventional rigs. They are therefore more cost effective and they consume much less power and energy. These rigs also have a very high level of accuracy in sample recovery through the straight borehole which causes a very small footprint. Also, the wells produced make it very easy to discover the precise location of contaminants. The information obtained from the samples helps to prevent consumption of hazardous substances and helps geologists to assess the risk of landslides, earthquakes and soil liquefaction.
