Soil Testing in Portland, OR


Contact Us

Heating oil presents an immediate environmental and hazardous threat to communities that require its use. The oil is stored in underground storage tanks (USTs) to minimize its environmental impact. While this storage method solves one problem, it also creates another. Over time, storage tanks corrode in the ground, increasing the risk of an oil leak, which can contaminate the nearby water and soil.

If you have a UST on your property, now is the time to schedule a tank search/locate and soil assessment. Alpha Environmental offers comprehensive storage tank and soil testing in Portland, OR. Using advanced technology and proven methods, we can evaluate the current condition of your storage tank and identify any oil contamination in the soil. 

Why You Need Your Soil Sampled & Tested

As an oil tank ages, it shows signs of corrosion. Eventually, the corrosion eats through the tank, allowing heating oil to leak. As the oil leaks, it contaminates the soil and water in its path. A tank search and sample provide an accurate assessment of the tank’s location, condition, and level of contamination in the soil.

You may need a tank to locate and sample in the following situations:

Although every UST in the United States should have documentation, some tanks can go years without an assessment. If you discover a tank on your property, Alpha Environmental can research the history of the tank and perform a complete assessment to determine what you need to do next.

Symptoms of a Leaking Oil Tank

Oil tank leaks slowly develop over time. As a result, the signs of a leak are not always evident. A single tank could contaminate the soil and water in surrounding areas for several years before you realize there is a problem. Therefore, it is important to identify the symptoms of a leaking oil tank. Some of the most common signs of a leak include

How We Assess Leaking USTs

Alpha Environmental follows a thorough, step-by-step process when locating and assessing your tank. However, each scenario is different and dictates precisely how we perform tank testing on your property. Below, we break down our procedure.

1. Locate the Tank

A tank that has been buried on your property for decades can be difficult to find. We use several methods to identify connecting pipes or related equipment. Our technicians also use specialized equipment to identify the size, shape, and depth of the tank. There may or may not be signs of oil or penetrations in the yard, so it is important to have certified personnel perform these assessments.

2. Soil Sampling

One of the best ways to identify a leak is to retrieve a soil sample around the tank. We may need to take samples inside the tank if there are signs of leaks or corrosion. Soil samples can help us locate the leak, the path of the oil, the type of oil in the ground, and how long the oil has been leaking. 

3. Decommission or Risk Assessment

Our certified heating oil tank supervisors perform clean decommissions, full decommissions, and risk assessments on a daily basis, depending on the assessment outcome. We ensure the site meets the requirements set by the EPA and DEQ, along with submitting the proper permitting and paperwork required prior to closure.

4. Soil & Groundwater Remediation

If a soil test reveals the presence of contamination, then soil and groundwater remediation may be necessary to resolve the issue. Various methods are available for cleaning up contaminated groundwater including thermal remediation, encapsulation, air sparging, and bioremediation. Which method is used depends on the type of contamination.

Alpha environmental was extremely helpful in navigating me through the process of testing some leftover construction debris for asbestos so I could take it to the dump. Their office manager spent time with me on the phone discussing the options for sample collection, and was extremely friendly in answering my many questions. Sample drop off at the office was easy and the results even came back a few days earlier than expected. Will definitely return if I need more sampling done!

We used Alpha Environmental Services to conduct our home inspection, radon testing, sewer scope and oil tank decommissioning. Every part of their service was really professional. They took so many great photos of the house during the inspection and offered lots of explanation on what they found. Great team. Highly recommend!
