The Doe Run Company operates the North Cross air monitoring station in Herculaneum. The station monitors exposure of a portion of the population to airborne lead. Until 2013, the Doe Run Company operated a primary lead smelter in Herculaneum. The monitoring station on North Cross Street can give an indication of how closing the facility has affected the concentration of airborne lead in the area. 

Pollutants

Lead

The primary and secondary ambient air standards for lead have remained at 0.15 micrograms per cubic meter since 2008. The primary standard reflects EPA's concern for public health while the second standard demonstrates concern for public welfare. EPA bases the standard on the highest rolling three-month average over a period of three years and two months. A monitoring site meets the standard when this rolling three-month average is less than or equal to 0.15 μg/m3.
