The reason we are contacted for an NJ oil tank removal is almost always because the clients want to sell their home, and the rusty underground tank is causing problems in completing a sale.  These large steel oil tanks were once commonplace for heating services throughout New Jersey, and buyers were not thinking about the serious problems and liability they could present down the road.  However, over time the old tanks corrode and sometimes develop cracks or holes, causing oil to leak into the surrounding soil, creating both environmental and public health issues.
