The Forest City air monitoring station lies near a secondary lead smelter owned by Exide Technologies. Since the mid-1970s, employees at the Cannon Hollow Plant have extracted lead from lead batteries to refine it and make it reusable. The state-operated monitor helps determine exposure to airborne lead from the smelter for a segment of the population.

From 1996 to 2000, the site was known as Schuylkill Metals-West, or the levee site. The EPA ID was the same as today's Forest City site. Monitoring ceased in 2000. The department reactivated the monitor in response to EPA monitoring regulations, 2008-2010. For more information, see page 8 of the 2012 Air Monitoring Network Plan compiled by the department's Air Pollution Control Program.

Lead (Pb) Data

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.
