My neighbors abandoned underground oil tank has been leaking for years and has contaminated the soil underneath my home, deck, garage and entire backyard. The present neighbor uses natural gas and has never used fuel oil. The clean up is going to be a 'big dig' vice a chemical clean-up due to the location of my home (New Jersey pinelands). The insurance company from the prior owner of my home is wrangling with my neighbors insurance company who is going to pay for the clean up. This has been going on for six (6) years. How do I get this process moving faster? Do I have a solid suit for damages?
