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.

The objective of this health assessment is to provide an evaluation of the health risks that may result from exposure to abandoned mine tailings in Klondyke, Arizona. The tailings are remnants from an earlier flotation mill and mining operation that was in business from the early 1900's until 1950. Environmental data indicate that the 70,000 cubic yards of tailings that remain on the property have contaminated the soil and nearby creeks with heavy metals. This report evaluates the potential pathways of human exposure to the contaminated media. The contaminants of concern further evaluated are lead, arsenic, cadmium, mercury, manganese, and boron. Child health issues and community concerns are also an integral part of the evaluation.
