Job description

For over 40 years, Leidos has provided environmental characterization and remediation services to Federal clients including the Department of Defense and Department of Energy. Leidos is seeking a Hydrogeologist to support our environmental site characterization, remediation, and restoration projects across the United States. The position can be remote/home office or based in Leidos offices near Reston, VA; Cleveland, OH; Seattle, WA; or St. Louis, MO.

The Hydrogeologist will possess solid field geology skills coupled with quantitative hydrogeologic aptitude. Specifically, the successful candidate must have a solid foundation in the mathematical/physical principles of groundwater flow and contaminant fate and transport but need not be a numerical modeler. Geologists with solid hydrogeologic skills will be considered as will hydrogeologists with solid geologic skills.

At Leidos, you will support and manage hydrogeologic aspects of environmental site characterization and remediation projects. Your role will span the entire project lifecycle from proposal to final report. Typical tasks will include developing technical approaches for investigations, cost estimating proposals, supporting work plan development, designing field investigations, developing and refining Conceptual Site Models (CSMs), technical report writing and review, and preparing/presenting technical presentations.

A significant portion of your workload will involve CERCLA Remedial Investigations (RI) for PFAS, but projects will range from preliminary assessments (PAs) to remedial actions (RAs). While PFAS investigations will be prominent, you will also encounter projects involving contaminants like chlorinated solvents, explosives, radionuclides, petroleum hydrocarbons, SVOCs, metals, and emerging contaminants. Occasionally, work may include water supply investigations.

You will work both independently and collaboratively with Leidos Project Managers, Senior Staff, junior staff, and interface with multiple offices and subcontractors. You will be supported by Leidos’ expert modeling team for fate & transport evaluation, groundwater flow modeling, and 3-D geologic modeling. You will also work closely with the PFAS Technical Advisory Team and our PFAS Technical Lead.

Hydrogeologist responsibilities:

1. Develop technical approaches to complex hydrogeologic site investigations and remediation projects, including determining monitoring well locations and construction methods to delineate contaminant plumes in various geologic settings.
2. Work with project teams to develop and refine Conceptual Site Models (CSMs) for contaminant fate, extent, and transport, collaborating with modeling staff.
3. Present technical information to project teams and stakeholders, including regulatory agencies and the public.
4. Analyze and interpret aquifer test and water quality data, laboratory results, and remedial system performance data to inform technical approaches.

Qualifications:

• Bachelor’s in geology or hydrogeology with at least 4+ years’ experience, or Master’s with at least 2+ years’ experience in environmental consulting.
• Licensure as a professional geologist, registered geologist, certified hydrogeologist, or similar.
• Ability to interpret hydrologic, hydraulic, chemical, geochemical, geophysical, geotechnical, and geologic data.
• Experience overseeing drilling operations, soil/lithologic logging, aquifer testing, and groundwater sampling.
• Excellent communication skills, capable of authoring technical reports and reviewing project documents.
• Experience in developing technical proposals and understanding of environmental regulatory frameworks, especially CERCLA and RCRA.

Computer Skills:

• Proficiency in MS Excel and Word, GIS, Surfer, aquifer test analysis software, and familiarity with MODFLOW, SESOIL, AT123D, VLEACH, HYDRUS, PHREEQC, and data visualization tools.
• OSHA 1910.120 hazardous waste worker certification (40-hour HAZWOPER) and ability to conduct field work at hazardous waste sites.
• Valid driver’s license and willingness to travel up to 10% domestically. U.S. Citizenship or Permanent Resident status required.

Preferred Qualifications:

• Master’s degree in hydrogeology, geology, or water resource engineering.
• Knowledge of PFAS investigations, project management experience, and familiarity with environmental regulatory requirements and modeling tools.
