Environmental Assistance Unit
The Environmental Assistance Unit provides geological and hydrological technical support to the public, consultants, and other programs within the department. This support includes technical assistance to the public related to geologic hazards such as sinkhole collapse and landslides; the department’s Solid Waste Program in the characterization, permitting and monitoring of landfills in Missouri; and the performance of hydrogeological site evaluations for liquid and residential waste in support of the Water Protection Program.
Geological and Hydrological Site Evaluations for Liquid Waste Facilities
Liquid Waste – Staff evaluate and determine the overall geologic and hydrologic limitations for proposed and existing liquid waste facilities. These systems include:
- Domestic Waste Lagoons
- Animal Waste Lagoons
- Municipal Wastewater Facilities
- Industrial and Process Facilities
- Land Application of Liquid Waste
- Subsurface distribution of Liquid Waste
- Large Scale Absorption (Cluster) Systems

Geological and Hydrological Technical Support
Solid-Waste – Staff provide regulatory oversight and technical support in determining the geologic and hydrologic characteristics of proposed solid waste facilities. Additionally, staff assist in the design and implementation of groundwater monitoring programs at approved facilities.

Liquid Waste – Staff provide technical support in determining the geologic and hydrologic characteristics of liquid waste facilities and assist in the design and implementation of groundwater monitoring programs.
Geologic Hazards – We provide assistance to the citizens of Missouri by evaluating the causes and impacts of sinkhole formation and collapse, landslide development and mine collapse. Geologists perform geologic and hydrologic evaluation to determine if collapse is attributed to a natural karst feature or is associated with the failure of a man-made feature. Learn more.
