Most homeowners have heard stories about leaking oil tanks & the impact the cleanup process has had on their properties. If you do have an oil tank leak, the cleanup process does not have to be a major project. This section will give you background about oil tank leaks, why they occur and most importantly what to expect during the leaking oil tank cleanup process. electricity physics ppt What is an oil tank leak?

• An oil tank leak usually refers to the escape of petroleum from a buried tank. gas station near me Underground tanks are designed to hold 250 to 1,000 gallons of heating oil based on the tank size. Oil tank leaks usually start out as a very small hole in the tank structure which causes the tank’s contents to leach into the surrounding soil sometimes at depths exceeding 10 feet. If there is a leak, the tank will need to be removed and the soil will require remediation. Unfortunately, leaks in the oil tank cannot be repaired, and the tank must be removed in order to clean up the surrounding soil.

• Most buried oil tanks are made of bare steel. When these tanks are placed underground, the steel may react negatively to the surrounding soil. Over time, this soil to steel reaction can start a corrosion process which wears away the tank metal over time. grade 6 electricity test This is how pinholes form in the steel and the tank develops leaks in its structure.

• A tank test or soil test will be the most reliable way to find out if your oil tank has a problem. A tank tightness test will evaluate whether the tank structure has a leak but will not be able to identify whether oil has escaped into the surrounding soil. A soil test can determine whether oil has leaked into the soil but works most reliably when the soil tested is taken from below the tank bottom.

• If the home has a sump pit, the homeowner should regularly examine any water in the sump for evidence of oil. electricity cost per kwh by country You can do this by using a clear glass jar to sample the water. gas laws worksheet with answers If there’s oil in the water sample, it will always float to the top because oil is lighter than water. The presence of heating oil in the sample means there is a high possibility your oil tank may be leaking.

• If the water table is involved in the cleanup, the homeowner will be instructed to contact their insurance company. At this point, the burden falls on the insurance company to verify the policy covers this event. gas 91 octane This usually means an adjuster is sent to examine the property and review the contractor’s findings. Most likely, the contractor will need to return to the property on another date to finish the remediation.

• If an oil tank leak is discovered during the removal process or there is a question about insurance coverage, the contractor will need to come back another day to complete the cleanup. The company should not leave your home in an unsightly condition. Typically, a tarp is placed on top of the contaminated area along with any available clean soil that has been excavated. All equipment should be removed when the contractor leaves for the day.

• As long as an insurance adjuster does not need to visit the site, the contractor can return in a day or two with several loads of back fill. The contractor will use a backhoe or similar machine to dig through the contaminated area until clean soil is reached. When the area is visibly clear of oil contamination, the soil is analyzed on-site to verify compliance with state remediation standards.
