Contaminant distribution in soil and water depends on such factors as soil properties the physical and chemical properties of the contaminant contaminant fate and transport in soil, groundwater or surface water and even the manner in which the contaminant was introduced into the environment. The knowledge of these issues coupled with available information on site history and background allows us to make valid assumptions in the planning phase on contaminant distribution and variability at the site.
