Geology & Hydrogeology Services

• Aquifer testing (pumping and slug tests) and interpretation

• Fate and transport modeling in saturated and unsaturated soils

• Conceptual design of groundwater contaminant recovery systems using one-, two- and three-dimensional groundwater transport models to predict potential contaminant migration pathways and receptors

• Design, installation, development and sampling of ground-water monitoring wells, recovery wells and piezometers

• Surface and subsurface soil investigations

• Hydrogeologic investigations and reporting

• Design and maintenance of groundwater recovery systems

• Geophysical investigations using electrical (conductivity and resistivity) and magnetic technologies

• Groundwater monitoring well maintenance and sampling services

• Hydrocarbon/contaminant cut-off wall integrity assessment

• Low Groundwater Yield/Non-Groundwater Bearing Unit Determinations - Cirrus has extensive experience with the requirements under the Texas Risk Reduction Program (TRRP) to qualify a site for either a Class 3 Groundwater Classification or a Non-Groundwater Bearing Unit Determination. Attainment of either of these standards has a dramatic impact on site cleanup levels.

• Expert witness testimony
