Environmental contamination can have a significant impact on the value and usability of a parcel of land. In cases where there’s a chance of the land being contaminated, it is smart to have an environmental assessment done. This initial assessment, known as a Phase I assessment, will help to identify whether or not a Recognized Environmental Condition exists. If it does, it is time to have a Phase II assessment done.
Geoprobe, a type of direct push drilling, is an ideal choice for this assessment. Direct push drilling involves driving hollow boring rods down into the ground using static and percussive force.
Why Is Geoprobe A Good Choice?
- It offers accurate soil profiling. The soil cores from the boring rods can give a good vertical picture of the soil layers and lithology below.
- It offers access to groundwater tables at discrete depths. This allows the assessment team to get a full profile of all water levels and any potential contaminants in each layer.
- It allows the assessment crew to take multiple kinds of samples. With so many contaminant types, it is impossible to use one kind of sample to get an accurate picture of potential contamination. Geoprobe allows the crew to send various sampling tools down with the boring rods. These tools can assess soil, air, soil vapor, and groundwater.
- It has a small footprint that does not limit access. The Geoprobe can be mounted to the back of a small truck or a skid loader to get into different areas.
- It is possible to take several samples in a restricted area. The boring rods have a small diameter. This makes it possible to take any number of samples from an area to get an accurate profile of the layers below and the extent of potential contamination.
- It creates minimal waste. With direct push boring, there is no water or mud needed. Almost all of the soil collected in the drilling process is contained in the boring rods.
- It can do a lot of work in a small amount of time. Direct push drilling can happen quite quickly using the Geoprobe equipment. It is markedly faster than conventional auger or rotary drilling.
- It is cost-effective. Geoprobe drilling requires a smaller crew than air or mud rotary drilling does. There is almost no site preparation required for the work. The quick rate of drilling keeps the drilling time to a minimum. That all feeds into a lower cost for the customer.
