"It’s always rewarding and fun to work on a site where you can implement various activities from various groups and be on-site with other employees for longer durations. "

What's been your most rewarding project(s) while at your firm?

One of the most rewarding projects I’ve worked on while at Terracon has been the Hardesty Federal Complex site in Kansas City, Mo. This is a larger project site that Terracon has been involved with for many years and it all started with a Phase I Environmental Site Assessment! Our client is the General Services Administration (GSA) which has environmental responsibility for the site. It has soil and groundwater impacts from historical operations involving trichloroethylene (TCE). It’s always rewarding and fun to work on a site where you can implement various activities from various groups and be on-site with other employees for longer durations. It provides for brainstorming, teamwork, being able to mentor and train, and perform site safety checks.

The project has allowed us to complete soil and groundwater investigations using direct-push, membrane interface probe (MIP), hydraulic profile tool (HPT), and sonic drilling technologies; perform well installations and groundwater sampling; asbestos building surveys and sampling; vapor intrusion activities both on site and in neighboring residences and businesses; excavation activities; building renovations; and soon a building demolition.

My second favorite project has been the former Kenneth Golf Manufacturing site in Shawnee, Kan. This site was known as one of the premier manufacturers of wooden golf clubs in the U.S. from 1928 until 2004. Unfortunately, the manufacturing process left a lasting environmental impact on the 60-acre parcel. Terracon has been on-site since 2008 when the site was enrolled in the Kansas Voluntary Cleanup and Property Redevelopment Program (VCPRP) due to metals-impacted soil from historical site activities. We have worked with several developers on this site, but it wasn’t until 2018 that we got a client that was willing to go all the way on this project. They will develop the site into a residential housing community after our team performed extensive soil investigations.

Most interesting place you've traveled for work?

I enjoy working on projects in St. Joseph, Mo., because it is so close to my home territory so it’s nice to visit. My most memorable place is a tie between Black Hills, S.D., and New Orleans!

What inspires you about your profession?

The fact that consulting is so diverse, especially environmental. You can work on a variety of environmental projects and topics. Sometimes these projects are routine, and you deal with them on a weekly/monthly basis, sometimes it’s once or twice a year, and sometimes you may only deal with it once in your career! Environmental consulting is always interesting and challenging.
