Professional Profile

Mr. De Cillis has over 30 years of scientific experience as an environmental consultant specializing in the field of hydrogeology. His areas of expertise include: aquifer and flow-system characterization and conceptualization; aquifer tests - - design, implementation, evaluation, and analyses; and characterization of ground-water/surfacewater relationships, and quantification of ground-water and surfacewater interaction (inflow/outflow, discharge/recharge).

Additionally, Mr. De Cillis expertise’s include: describing and delineating the nature and extent of ground-water and aquifer contamination; defining and conceptualizing ground-water flow and contaminant transport relationships, together with analyses and modeling; and characterizing surface and subsurface contamination and evaluating remediation alternatives.

Mr. De Cillis applies these technical and quantitative proficiencies/skills in a variety of hydrogeologic investigations (design, implementation, and data evaluation and analyses phases) encompassing all aspects of water resources investigations (supply, development, protection, management), soil and ground-water contamination, environmental litigation, report preparation, presentations of technical material and issues to technical audiences and non-technical audiences, technical and peer review activities including Quality Assurance and Quality Control (QA/QC) scrutiny, multi-level and multi-tasking project support (field hydrogeological tasks through data-related interpretive tasks through report preparation and/or preparation assistance), some examples of which are provided below.

Throughout his professional career, Mr. De Cillis has always been a vital resource when technical and quantitative skills are required to evaluate and provide practical solutions to hydrogeologic problems - - from fundamental problems in relatively simple hydrogeologic environments to complicated problems in very complex hydrogeologic environments.

Thus, Mr. De Cillis adds a new dimension to, and further strengthens, the interdisciplinary team of highly experienced professional environmental scientific and engineering team that ETG relies on to address, solve, and manage the environmental problems and needs in today’s world while simultaneously addressing the needs of their clientele in a cost-effective and cost-efficient manner.

A Certified Professional Geologist (CPG) with the American Institute of Professional Geologists (AIPG) and a member of the Long Island Association of Professional Geologists (LIAPG), Mr. De Cillis is a graduate of Adelphi University where he received his Baccalaureate of Science through the Biology and Earth Sciences Departments Interdisciplinary Program, and then completed post-graduate studies in Geology, Hydrology, Environmental Sciences, and Education at the University of Vermont, before earning his Master of Science in Earth Sciences with a specialization in Hydrogeology from Adelphi University (graduating with a 4.0 GPA).

Mr. De Cillis began his professional environmental consulting career as a Hydrogeologist for Environmental Associates in Burlington, Vermont. He then joined Geraghty & Miller, Inc. (G&M) in their Long Island based, New York offices, where his technical and quantitative skills enabled him to work his way up from Hydrogeologist to Principal Hydrogeologist, while simultaneously becoming G&M’s Director of Ground-Water Modeling - - as well as a Founding and Principal Member of the G&M Ground-Water Modeling Group - - in addition to becoming a Director of QA/QC, and an Associate of the firm. Throughout his tenure at G&M, he served as a corporate-wide resource by providing technical and quantitative support and services.

Mr. De Cillis next brought his expertise and experience to Roux Associates, Inc. (RA) in their Huntington and Hauppauge, New York offices, furthering his technical and quantitative expertise’s, and expanding and increasing his environmental consulting experiences by serving as a corporate-wide resource as a Principal Hydrogeologist, and the firm’s Corporate Director of Ground-Water Modeling, and Corporate Director of QA/QC. He completed his employee time at the larger and more diversified firm of Blasland, Bouck & Lee, Inc. (BBL), again providing corporate-wide technical and quantitative support, while continuously on the road among the Hauppauge and Syracuse, New York; Cranbury, New Jersey; and Boca Raton, Miami, and Tampa, Florida offices, as a Principal Hydrogeologist in company positions as an Associate of BBL, the Corporate Director of Ground-Water Modeling, and a Division Manager of Specialty Service.

After 20 years of working for environmental science, and then science and engineering, firms, Mr. De Cillis went out on his own providing logistical, technical, and quantitative hydrogeologic services through Quantitative Hydrogeology, Inc. (QHI). Here, he again teamed with one of his former officers and colleagues from G&M, and co-founder of ETG, William J. Seevers, P.H., and a former professor in environmental studies, and other co-founder of ETG, Albert Machlin, P.E., DEE.

Representative Experience

Seminar Series - - Educational Tool & Promotional / Marketing Functions

Principal Author & Presenter of the Practical Applications of Modeling to Ground-Water Problems section of the semiannual Geraghty & Miller, Inc., (1980s) The Fundamentals of Ground-Water Contamination seminar series to representatives of industries, manufacturing companies, utilities, law firms (and individual attorneys), municipalities, Federal and state agencies (regulatory and non-regulatory), engineering and consulting firms (including numerous competitors), financial institutions, real estate agencies (business and private/personal), colleges and universities (faculty and students), and numerous other interested parties and individuals.

New York

· Principal Modeler & Co-Field Manager, Old Bethpage Landfill, NY - - responsible for the installation and sampling of monitoring wells; evaluation of ground-water elevation (head) and quality (leachate) data; construction of head and flow, and leachate/quality plume maps (aerial and cross-sectional); research and compilation of area-specific and regional aquifer/flow-system hydraulic parameters (K_x, K_y, K_z, T, S, S_y), geology, and geometry (m, m'); collation of site-specific and published data; construction of the conceptual model of the ground-water flow and transport system; and construction (formulation/generation) of the mathematical, numerical ground-water flow and mass transport model. Modeling was used to: evaluate passive remediation (natural attenuation) vs. active remedial scenarios (pumping and treatment) remediation alternatives; assess potential contaminant impacts to down-gradient and cross-gradient public supply wells; site potential locations for replacement public supply wells; and provide a tool for negotiations among the municipality, their engineers, the New York State Attorney General’s office via their scientific (hydrogeologist and chemist) representatives, and the New York State Department of Environmental Conservation.

New Jersey

Principal Modeler - - responsible for ground-water flow and contaminant transport including impacts to surfacewater bodies and public supply wells surrounding (the then #3 NPL) Prices Landfill Superfund Site in New Jersey. Modeling also served as a tool for negotiations among the PRP’s, attorneys, and state and Federal regulators and agencies. (Additionally, modeling was used to counter incorrect results and impacts forecasted by the opposition’s flawed flow and transport modeling study, in this “battle of the models” case with impending litigation, in which the modeling again served as a negotiation tool between the opposition’s modeling team and my modeling tasks.)

Confidential / Litigation Pending, Mid-Western State

Litigation Support as a Principal Hydrogeologist providing technical support to the Expert Witness ‑ ‑ reviewed and evaluated consulting report’s soil-quality data; assisted in formulating, and providing technical back-up for, expert’s opinions; and prepared figures/exhibits for testimony. Technical scrutiny revealed the opposing expert’s opinions were wrong due to incorrect evaluation and analyses (application) of data used to delineate the nature and extent of PCB and solvent contaminated soils (over delineated), and consequential over-estimate of the cost for soils’ remediation; (my) corrected and revised delineation resulted in a cost-savings to the client of, a minimum $10M (between $10M and $14M), which may be used as part of a future negotiated settlement.

Massachusetts

Principal Hydrogeologist and Technical Manager (dual role in a co-managed project) - -responsible for the design, implementation, and analyses of aquifer tests (8-hr step test and 72-hr pumping test) used in the construction of a ground-water flow and transport model for the Industri-Plex Superfund Site in Woburn, Massachusetts, (landfills leaching contaminated, hazardous waste). Aquifer testing and analyses were first used to quantify aquifer parameters (coefficients) and to determine ground-water/surfacewater relationships. Site-specific data were used to supplement researched regional published information and data for the characterization and conceptualization of the ground-water flow system, and interaction between ground water and surfacewater, i.e., to construct a conceptual flow model. The conceptual flow model was combined with water-quality data to construct a conceptual flow and transport model, then used to construct a 3‑D numerical ground-water flow and transport model. Modeling served: to assess and delineate contaminant migration pathways; to evaluate pumping and treatment remedial alternatives, to estimate contaminant loading to surfacewater bodies (Aberjona River, Halls Brook, and Mishawum Lake), and for a negotiation tool among PRPs, and state and Federal agencies.

Connecticut and Massachusetts; New Jersey and New York
