About Loess Hills Environmental
We train. We investigate. We serve.
"Environmental" and "EHS" can mean a lot things. Some clients are looking for a class to close a training gap, others need support to manage a portfolio of former release sites. Our mission is to help you clarify the need and then meet it promptly and effectively.
Our goal is to be your first call or email when seeking site investigation or EHS services in Iowa and Nebraska. If it turns out we are not the expert you need, we will work to get you connected with the right organization. Contact us today to get started.


In June 2023 Loess Hills Environmental became certified by the Small Business Administration as an SBA Service Disabled Veteran Owned Small Business (SDVOSB) and by the Iowa Economic Development Authority (IEDA) as a Targeted Small Business (TSB).
Most of our work is near Omaha and Sioux City, but "local" projects stretch from Cozad, NE to Mason City, IA. Nationally, our instructors have traveled to Miami, Yakima, and many places in between.
We know from experience it can be difficult to find contractors in northwest Iowa and northeast Nebraska. We are here to serve.


Owner Korey Brunken is a Professional Geologist (NE) and Environmental Engineer (NE) that has completed investigation, compliance, and design projects throughout the Midwest and Mideast.
