Stephanie J. Bialobok, P.G.
Consulting Geologist


Ms. Bialobokís professional career began in 1976. Since joining Lourie Consultants in 1993, she has coordinated the firmís geological and geoenvironmental services.

She has planned and managed environmental site assessments (ESAs), audits, and other "due diligence" studies. She also has designed and supervised field and analytical laboratory programs, developed site-specific health and safety plans, evaluated field and laboratory data, and planned and conducted site-specific geologic and geoenvironmental investigations for commercial, industrial, and governmental clients. Representative projects include:

Performing numerous ESAs including multiple ESAs with 10 or more sites and properties exceeding 1000 acres.
Supervising and performing underground storage tank (UST) studies, including groundwater evaluation and site remediation, compliance, and risk-based corrective action (RBCA and RECAP) issues.
Developing groundwater monitoring programs and subsequent client education programs for nonhazardous industrial sites.
Participating in landfill siting and permitting studies, including geologic site characterization, regulatory negotiation, and public hearings.
Designing and managing site contamination assessments for nonhazardous oilfield wastes (NOW).
Developing and conducting site audits of exploration and production (E&P) facilities in the US and South America.
Designing and implementing site assessment programs and performing groundwater monitoring studies for industrial facilities in the Gulf Coast.
Developing and implementing programs for in-place impoundment closure and off-site material disposal.

Before entering the consulting profession, Ms. Bialobok worked for the oil industry as an exploration geologist. She also worked for the US Department of Energy (DOE) as Project Manager for its Waste Management Project.


Ms. Bialobok holds a BA Chemistry and a MS Geology from West Virginia University. Ms. Bialobok has also completed the 40-hr OSHA training program for hazardous waste site workers and the 8-hr OSHA supervisory training program. She also has attended numerous continuing professional development conferences and seminars.


Ms. Bialobok is a licensed professional geologist registered in Texas. She is an active member of ASFE/The Geoprofessional Business Association, and has served on its Member Services Committee, and has served as vice chair of its Geoenvironmental Committee. As vice chair of the Geoenvironmental Committee, she coordinated review activities of hundreds of Phase I ESA proposals and reports, which led to a published report that documented the standard of care used for conducting Phase I ESAs. She also developed guidelines to use for selecting environmental analytical laboratories.  Ms. Bialobok also was one of the early members of the Institute of Brownfield Professionals (IBP).

Ms. Bialobok has presented information at an ASCE technical conference that addressed the environmental and regulatory issues associated with developing Brownfield sites. She also has presented information at a Louisiana Department of Environmental Quality (LDEQ)-sponsored seminar, which addressed field investigation processes available for contaminated sites.

CEO and Consulting Engineer


Mr. Lourie began his professional consulting engineering career in 1979. Combining project experience with continued education has resulted in well-developed project leadership, execution, and management skills. Before forming Lourie Consultants in 1992, he spent 9 yr directing the technical and financial operations of an international consulting firm's multiple-office practice in Louisiana.

He has performed and supervised studies for a wide variety of onshore and offshore projects. His expertise has been applied to numerous environmental, geotechnical, and materials engineering and testing projects for industrial, commercial, and governmental clients. These services have included:

Developing, performing, and supervising geotechnical programs for large, heavy, and settlement-sensitive industrial plant structures; single- and multiple-story buildings; waterfront and coastal protection projects; and offshore platforms, mobile rigs, and other structures in the US and internationally.
Performing shallow and deep foundation design and developing construction recommendations for structures founded on weak and compressible soils, as well as those where active (expansive and potentially expansive) soils are present.
Formulating and conducting forensic investigations and engineering studies to assess failure causes and identify remedial measures for sheet pile walls, earth slopes, earth levees, foundations, and pavement systems.
Designing, implementing, and supervising comprehensive geoscience studies for solid waste landfill siting, design, construction, and expansion projects.
Establishing QA and QC practices for earthwork and geosynthetic monitoring and testing and preparing certification documents for solid and hazardous waste landfills.
Developing laboratory and field testing procedures to evaluate and control in-place impoundment closure and off-site disposal.
Managing field construction and conducting on-site verification testing for a coal mine waste disposal research study.
Directing studies to characterize soil and groundwater at RCRA sites and nonhazardous oilfield wastes (NOW) sites.
Performing and supervising environmental site assessment (ESA) projects and underground storage tank (UST) studies, including soil and groundwater evaluation, site remediation, compliance issues, and risk-based corrective action (RBCA and RECAP) plans.


Mr. Lourie holds the BSCE and MSCE (with concentrations in Construction Management and Geotechnical Engineering) from the Illinois Institute of Technology. Mr. Lourie also has completed the 40-hr OSHA training program for hazardous waste site workers and the 8-hr OSHA supervisory training program.
