Work Experience
Scott Prinos began his career as a hydrologic Technician with the USGS in the early 1990s in the Dekalb Sub-District Office, in Illinois where he collected hydrologic data and assisted in hydrogeologic examinations of EPA Super Fund sites. In the mid-1990s Prinos transferred from Illinois to Florida, were he served as the Groundwater Data Collection Program Coordinator in south Florida for 12 years and also as a supervisory hydrologist for 9 years. During this period Prinos worked closely with the partners of the USGS and the Data Section Chief to evaluate the groundwater level and salinity monitoring networks of the USGS in south Florida and to implement the monitoring changes necessary. He conducted numerous informal network evaluation assessments, so that USGS partners could better understand the effects of proposed network changes and how those changes might impact resource-management decision making. He was lead investigator in the project Design of a Real-Time Groundwater Level Monitoring Network and Portrayal of Hydrologic Data in Southern Florida. This was a precursor to, and inspiration for, the USGS Groundwater Watch webpage.
Prinos transferred to the Hydrologic Investigations Unit in 2009. He developed the concept of correcting individual electromagnetic induction logs into time-series electromagnetic induction log (TSEMIL) data sets which improved the ability to identify changes in bulk resistivity through time. He has collaborated with other USGS hydrologists on projects in southern Florida that have included geospatial salinity network evaluations, mapping the inland extent of saltwater intrusion, creation of potentiometric maps, collection, analysis, and publication of geophysical surveys, design of improved monitoring well designs to maximize the geophysical and geochemical information that can be gathered, and hydrostratigraphic analyses. Prinos oversaw continued advancements to the 2000 prototype website to include various types of groundwater and surface water data which most recently led to collaboration on the Water Level and Salinity Analysis Mapper.
Prinos became a Supervisory Hydrologist in the Hydrologic Investigations Unit in 2020.

Development of a web-based tool for coastal water resources management
The sustainability of coastal water resources is being affected by climate change, sea level rise, and modifications to land use and hydrologic systems. To prepare for and respond to these drivers of hydrologic change, coastal water managers need real-time data, an understanding of temporal trends, and information about how current and historical data compare. Coastal water managers often must makMapping water levels in the Biscayne aquifer
To help inform decisions necessary for urban planning and development, Miami-Dade County Department of Regulatory and Economic Resources partnered with USGS to produce statistical analyses and maps representing mean, high, and low water-level conditions in the surface water and groundwater of Miami-Dade County.CFWSC Science Highlights

Data Pertaining to Mapping the Approximate Inland Extent of Saltwater at the Base of the Biscayne Aquifer in Miami-Dade County, Florida, 2018
The U.S. Geological Survey (USGS), in cooperation with Miami-Dade County, mapped the approximate inland extent of saltwater intrusion in eastern Miami-Dade County in 2018. This approximation required acquisition and compilation of relevant data collected by the organizations: Florida Department of Environmental Protection (FDEP), Florida Keys Aqueduct Authority (FKAA), Florida Power & Light CompanTemperature data collected in the Indian River Lagoon to evaluate groundwater seepage, Brevard County, Florida
The data set includes temperature data from the base of the water column and below the bottom of the Indian River Lagoon, Brevard County, Florida. Data were collected near Eau Gallie, Melbourne, Florida and Riverwalk Park, Rockledge, Florida, on the western shore of the Lagoon. These data will ultimately be used to evaluate groundwater seepage.

Using heat as a tracer to determine groundwater seepage in the Indian River Lagoon, Florida, April–November, 2017
The U.S. Geological Survey, in cooperation with the St. Johns River Water Management District, conducted a study to examine water fluxes in two small study areas in the Indian River Lagoon. Vertical arrays of temperature sensors were placed at multiple locations in the lagoon bed to measure temperature time series in the vertical profile.

Coastal communities are increasingly concerned about the dynamic balance between freshwater and saltwater because of its implications for societal, economic, and ecological resources. While the mixing of freshwater and saltwater sources defines coastal estuaries and lagoons, sudden changes in this balance can have a large effect on critical ecosystems and infrastructure.

Florida's communities are largely dependent on freshwater from groundwater aquifers. Existing saltwater in the aquifers, or seawater that intrudes parts of the aquifers that were fresh, can make the water unusable without additional processing. The quality of Florida's saltwater intrusion monitoring networks varies. In Miami-Dade and Broward Counties, for example, there is a well-designed networkAuthorsScott T.

In 2011, the U.S. Geological Survey and the U.S. Army Corps of Engineers began monitoring the saltwater interface near Lake Okeechobee to evaluate changes in interface depth that could possibly be related to the repair of the Herbert Hoover Dike. A seepage barrier (or cut-off wall), installed by the U.S. Army Corps of Engineers, is a wall of grout designed to protect the Herbert Hoover Dike from iAuthorsScott T.

Intrusion of saltwater into parts of the shallow karst Biscayne aquifer is a major concern for the 2.5 million residents of Miami-Dade County that rely on this aquifer as their primary drinking water supply. Saltwater intrusion of this aquifer began when the Everglades were drained to provide dry land for urban development and agriculture.

Saltwater intrusion threatens the water supplies of many coastal communities. Management of these water supplies requires well-designed and properly maintained and operated salinity monitoring networks. Long-standing deficiencies identified in a salinity monitoring network in southwest Florida during a 2013 study (Prinos, 2013) help to illustrate the types of problems that can occur in aging and pAuthorsScott T.

The installation of drainage canals, poorly cased wells, and water-supply withdrawals have led to saltwater intrusion in the primary water-use aquifers in southwest Florida. Increasing population and water use have exacerbated this problem. Installation of water-control structures, well-plugging projects, and regulation of water use have slowed saltwater intrusion, but the chloride concentration oAuthorsScott T.
