A tank sweep is commonly performed after a visual inspection. Using a metal detector, the technician will walk the grounds in all directions around the house to search for any buried metallic objects. The detector can locate metallic objects up to eight feet below ground. If a suspicious object is discovered, the technician will mark the location and describe it in the report that is generated. This possible abandoned oil tank can now be dealt with prior to the sale and removal/remediation costs will be placed on the owner of the property.
The cost to perform a tank sweep and inspection is reasonable compared to the cost of potentially remediating contaminated soil in the future from an underground oil tank you didn’t know existed.
