Environment Hydrogeologist III

Overview:

Hydrogeologist III evaluates hydrogeological, chemical and biogeochemical data derived from site investigation activities to determine nature and extent of contamination, to quantify contaminant fate and transport to support risk assessment and remedial decision-making, to aid in the identification and assessment of remedial technologies and development and screening of remedial alternatives, and to evaluate the performance of operating remedial systems. Further, the Hydrogeologist III designs and implements soil, soil gas and groundwater remedial strategies to address risks to human health and the environment.

Responsibilities:

TYPICAL RESPONSIBILITIES/DUTIES: Hydrogeologist III typical responsibilities and duties include, but are not limited to the following:

Prepare and peer review groundwater investigation work plan, designs groundwater monitoring network to support site characterization and remedy performance evaluation

Evaluates data generated by field activities to provides detailed interpretations of subsurface lithology, groundwater flow conditions, and nature and extent of contamination for inclusion in reports or presentations

Prepare designs for more complex or multi-phase/multi-media groundwater, vadose zone, and soil vapor/vapor mitigation remedial systems - including the placement of extraction wells/injection locations and vertical intervals, well spacing, injectant dissemination methodology, injectant dosing, pumping and injection rate (water and/or sol vapor), etc.

Direct and Oversee sample teams performing environmental sampling tasks; such as collection of soil, surface water, groundwater, soil gas, or other environmental media for physical or chemical analysis; and ensures the design, installation and development of groundwater monitoring wells and remediation wells are conducted according to project work plan specifications

Model multi-phase/multi-media contaminant fate and transport in soil vapor, vadose zone moisture, groundwater and surface water

Models optimization of operating remedial systems using manual (trial and error) and advanced automated optimization models in support of improving remedial system performance/reducing life cycle costs

Supports assessment and development of transport/receptor-based and/or leaching-based cleanup values in support of risk assessment and remedial decision making

Author RFQs and assist in procurement and selection of technical and specialty subcontractors, consultants, service providers, and materials to accomplish scope of work

Support development of modification proposals and claims/request for equitable adjustment (REA)

Performs peer review of the work performed by more junior Hydrogeologists

Keenly aware of relevant guidance and procedures for calculating and evaluating capture zones, boundary conditions, air and soil gas flow mechanics, and flow and transport characteristics

Proficient with analytical tools/models for the assessment of flow and transport and natural attenuation

Ability to apply industry standard flow and transport modeling software - including conducting parameter estimation, sensitivity testing, and application of optimization software is preferred

Functions as a team leader, providing direction and technical guidance to project team members and mentors junior Hydrogeologist

Achieves and maintains professional licensing and certifications (Professional Geologist, Certified Hydrogeologist [CHG]; Professional Hydrology Certificate; etc.).
