The Glover air monitoring station lies near a primary lead smelter that has not been operating since 2003. However, the area still experiences sporadic lead emissions from activities to deconstruct the primary smelter. In 2017, the department authorized the removal of several trees on the property near the monitor so that the monitor's location could continue to meet EPA's siting standards for monitoring stations. One of the tree stumps is visible in the picture.

Lead (Pb) Data*

The primary and secondary ambient air standards for lead have remained at 0.15 micrograms per cubic meter (μg/m3) since 2008. The primary standard reflects EPA's concern for public health while the secondary 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.
