Bunker Hill Site
Figure 1 shows the average blood lead concentration among children living in the five Idaho communities associated with the Bunker Hill Mining & Metallurgical Complex Superfund site. Blood lead levels fell from approximately 65 µg/dL to 2.7 µg/dL during the period 1974 to 2001. The decline in blood lead concentration during this period is associated with a variety of health intervention and Superfund activities at residential and non-residential areas of the Bunker Hill site that began in the mid-1980s.
