One of the more important aspects that can be revealed by this search is the possibility of the land being contaminated by previous owners eg a Mining Company. Responsibility for cleaning up contaminated land will lie with the person/company who caused the contamination in the first instance. However, there is the potential risk that this expense may fall to you in the event that, for example the Mining Company no longer exists. Other environmental matters that may be revealed are whether the land is near a landfill site or whether there are any factories in the area discharging any hazardous substances.
