Project PurposeAddress concerns in the community about toxic air
emissions and also reports of creosote odors and emissions continuing to occur from the old Kerr-McGee plant site.
Until 2003, the Kerr McGee Chemical Corporation used creosote and creosote tar solutions or pentachlorophenol to make pressure treated wood products. Contamination was later discovered in sediment samples from off-site drainage ditches and in soil samples from private residences.

VOC Sampling60 VOCs started being monitored in January 2013
1 in 6 days – 24 hour samples
The VOC sites are the Kerr-McGee site and the Stokes-Beard Elementary School Site.
Sanderson Plumbing is a toilet site and custom molding manufacturer where its HAPS are emitted from surface coating operations.
Columbus Brick uses natural gas-fired dryers and kilns. The HAPs are emitted from the actual drying of the bricks.
SVOC Sampling
A separate sampler is used to collect SVOC samples at the Kerr-McGee property.
22 SVOCs started being monitored in April 2013 and will operate for a period of three months. The monitor will then be moved to another location on the property and operated for three months.
