The primary pathways for exposure to chemical contaminants at this residence would be inhalation of suspended dusts or incidental ingestion of contaminated soil or dust.

Only one soil sample was collected, and there is no information regarding the collection depth and sampling location. However, the concentrations of pesticides detected in this soil sample are below the Agency for Toxic Substance and Disease Registry's comparison values and are not at levels of health concern.

The attic sample contained arsenic at 20 parts per million and numerous organochlorine pesticides. No information is available regarding the nature of the material collected or the source of the pesticide contamination. Long-term contact with this material could be of health concern. However, because the material was found in the attic, it is unlikely that frequent contact with it would occur.

An expert from the Centers for Disease Control and Prevention indicated that the various fungi detected in the air samples from this residence are typical of those found in indoor air and that no weight should be placed on the findings with respect to adverse health effects [2].
