Doe Run site: Post Office #2

Address for both sites: Highway 49
Glover, MO 65439
County: Iron
Pollutant monitored: Lead (Pb)
Date established for both: March 31, 1992

Coordinates for site at Post Office #2:
* Latitude: 37.48532°
* Longitude: -90.68991°
EPA site number: 29-093-0027

Doe Run site: Big Creek #5

Coordinates for site at Big Creek #5
* Latitude: 37.47211°
* Longitude: -90.68919°
EPA site number.: 29-093-0029

The two sites stand near a now-closed primary lead smelter in Glover. The site at the post office lies north of the old smelter; the site at Big Creek #5, south of the old facility. The smelter hasn't been in operation since 2003; however, the area still experiences sporadic lead emissions from activities to deconstruct the primary smelter.

Since the air monitors are on land inaccessible to the public, EPA classifies them as non-ambient air monitoring stations and does not consider data from them when determining whether the area is in compliance with federal standards for lead.

Lead (Pb) Data*

The primary and secondary ambient air standards for lead have remained at 0.15 micrograms per cubic meter since 2008. 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.

* The town of Glover is near the Viburnum Trend, an area rich in lead ore and home to several mines operated by Doe Run. The area has become known as the new lead belt of Missouri.
