The United States Environmental Protection Agency asked the Arizona Department of Health Services, Office of Environmental Health, to provide an evaluation of the health hazards that may result from exposure to soil and soil gas contaminants present on the West-Cap site, located just north of the Tucson International Airport. Improper waste disposal practices from previous industrial activities at the site have resulted in contamination of on-site soil and soil gas. The objective of this health assessment is to assess the potential adverse health impact to on-site workers from exposure to the on-site contaminated soil and soil gas. Community exposures are not presented in this public health assessment.

The objective of this health assessment is to provide an evaluation of current and future potential health risks that may result from exposure to residual organochlorine pesticides at Franklin Elementary School in Phoenix, Arizona. The school has been unoccupied for the past 10 years. The historic school building is being restored by the school district, which plans to reopen the building for use as an elementary school. Several organochlorine pesticides were discovered in the soil during routine environmental sampling done in conjunction with the renovation. In particular, chlordane and dieldrin, banned in the United States in the early 1980's, were present in concentrations above screening levels.
