About Us

Larsen & Associates, Inc. formed in 1992 in Kansas. The company began by specializing in environmental report writing for vendors in the Kansas Department of Health and Environment (KDHE).


Since then, Larsen & Associates has expanded into environmental drilling, direct-push probing, and sampling soil and groundwater. Our team of experts includes geologists, environmental scientists, draftsmen, drillers, business specialists, and administration support. Our field equipment includes drill rigs, a direct push rig, trailers and all other equipment necessary to conduct work related to environmental assessments and remediation.


We are committed to working safely, having high ethical standards, and providing quality work on time.
