Youngdahl offers a broad range of environmental geology services. Our environmental professionals, with proven technical expertise and management skills, provide services to a wide range of clients in the areas of environmental site assessment, hydrogeologic investigations, remediation, groundwater resources, and landfill siting, closure, and expansion.

Youngdahl has provided environmental services on properties historically used for agricultural, industrial, mining properties, and more; which are being re-purposed for commercial, residential, industrial, office, and many other potential uses.
