Elizabeth A. McCarty, Staff Hydrogeologist
As a Staff Hydrogeologist, Ms. McCarty’s foremost area of professional concentration is in water resources exploration, development, management and protection. Ms. McCarty is accomplished in producing, using, interpreting and critiquing scientific work product using Geographic Information Systems (GIS). Ms. McCarty possesses background and experience in fracture trace analysis; aquifer test design and analysis; mathematical modeling of hydrogeologic systems; groundwater discharge permitting and other wastewater discharge evaluations.
Much of the work Ms. McCarty performs entails subsurface hydrogeologic investigations. In the field she selects optimal well locations based on scientific and regulatory considerations. After coordinating for agency approval, she directs and oversees the drilling and installation of water supply wells, monitoring wells and piezometers (as the circumstance requires). She then performs pumping tests and/or slug tests and carries out sampling and analysis protocols.
Ms. McCarty possesses proficiency in the use of field equipment and in the interpretation of the collected data, including differentially-correcting Global Positioning Systems (GPS), pressure transducers and other water quality monitoring equipment. During her graduate studies at the University of Delaware, Ms. McCarty worked extensively within the GIS framework of ESRI’s ArcMap 9.2 and 9.3. Her master’s thesis was centered on the use of GIS to quantify the environmental effects of major storms.
Education:
- B.S.: Department of Marine Studies, Coastal Carolina University
- M.S: Department of Geology, University of Delaware
Prof. Training and Certifications:
- MDE Certified for Potable Water Sampling
- MDE Registered Sanitarian-In-Training
Relevant Professional Experience:
GIS Application:
- Used GIS to portray and analyze spatial relationships between hydrogeologic data layers, such as topography, geology, fracturing, well locations, septic locations, other existing and planned improvements, and property boundaries.
- Prepared GIS maps and analyses illustrating the basis for hydrogeologic recommendations of well and percolation test locations.
- Applied GIS to prepare hydrogeologic cross-sections and other illustrations of the potential for adverse well interference in a confined, multi-layer coastal plain aquifer system as well as in fractured bedrock settings.
- Compiled databases of neighboring property owners and stakeholders to support the public participation component of permit applications.
Hydrogeologic and Soils Fieldwork:
- Oversaw and geologically logged the drilling and installation of test wells, monitoring wells, piezometers and production wells.
- Performed aquifer pumping tests in accordance with regulatory agency procedures.
- Used both digital and manual field equipment to monitor wells (domestic and otherwise) for drawdown and water quality effects of both drilling and testing.
- Performed percolation tests and described and classified soils to support septic system designs.
- Sampled wells and improved water supplies in accordance with agency-developed requirements.
Data Evaluation, Modeling and Reporting:
- Analyzed pumping test field data to quantify aquifer parameters and estimate sustainable yields of both new and existing public supply wells.
- Conceptualized and executed analytical groundwater flow models to evaluate the impacts of proposed groundwater withdrawals and discharges.
- Analyzed slug test data to quantify groundwater mounds arising from proposed wastewater discharges
- Prepared permit applications, technical reports and other regulatory agency submissions.
- Assisted in preparing for expert testimony and litigation support through graphics production and supporting research.
