Biography
Dan received a B.S. in Environmental Science in 2009 and an M.S. in 2013 from the Department of Geography and Environmental Systems at the University of Maryland, Baltimore County (UMBC). His research focused on using LiDAR to track watershed-scale geomorphic changes associated with the suburbanization of small, historically agricultural watersheds in Montgomery County, MD. During his degrees, Dan worked as a research support specialist at the Baltimore Ecosystem Study Long Term Ecological Research station, assisting in the long term data collection of water, sediment, and vegetation samples associated with the project. Since joining the U.S. Geological Survey as a Geographer in 2012, Dan's work has focused on the use of Geographic Information Systems (GIS) and remote sensing data to solve watershed-scale questions associated with catastrophic storms, urban development, and resource protection. Dan also serves as the lead of the Geospatial Analysis and Applications Core Technology Team, a group of geographers, programmers, and statisticians focused on questions related to contaminants and environmental health across spatial scales.

Understanding the Effects of Stormwater Management Practices on Water Quality and Flow
Urban development can have detrimental impacts on streams including altering hydrology, increasing nutrient, sediment, and pollutant loadings, and degrading biological integrity. Stormwater Best Management Practices (BMPs) can be used to mitigate the effects of urban development by retaining large volumes of stormwater runoff and treating runoff to remove pollutants. This project focuses on...

About the Laboratory
Scientists within the Geospatial Analyses and Applications Team develop and apply geospatial analytical methods to answer broad-scale questions about source-sink and cause-effect relationships between contaminants and vulnerable communities. Multivariate statistics are used to identify connections between landscape gradients and observational data....
Potential contaminant sources and other landscape variables summarized for NHDPlus Version 2.1 catchments within the Chesapeake Bay Watershed (ver. 1.1, March 2020)
This dataset consists of 262 variables which describe various known and suspected point and non-point sources of contaminants and endocrine disrupting compounds (EDCs) throughout the Chesapeake Bay Watershed. Contaminant data was summarized to the NHDPlus Version 2.1 catchment level (1:100K). Contaminant data summarized span a time range of 2001 to 2016 and include regulated facilities%
Digital Polymerase Chain Reaction (dPCR) and Presence/Absence Quantitative Polymerase Chain Reaction (qPCR) Data From the Sediment-Bound Contaminant Resiliency and Response Strategy Pilot Study, Northeastern United States, 2015
The purpose of these datasets was to define which samples contained antibiotic resistance genes (screened antibiotic resistance gene targets) and Vibrio species, the number of detectable targets per sample and the quantity of those respective gene targets per gram of soil. These data were determined from samples collected in the northeast United States, in support of the Sediment-Bound...
Exposure potential of salt marsh units in Edwin B. Forsythe National Wildlife Refuge to environmental health stressors
This dataset displays the exposure potential to environmental health stressors in the Edwin B. Forsythe National Wildlife Refuge (EBFNWR), which spans over Great Bay, Little Egg Harbor, and Barnegat Bay in New Jersey, USA. Exposure potential is calculated with the Sediment-bound Contaminant Resiliency and Response (SCoRR) ranking system (Reilly and others, 2015)
Fourier Transform Infrared (FTIR) screening of extracted sediments for samples collected for the Sediment-Bound Contaminant Resiliency and Response Strategy pilot study, northeastern United States, 2015
Coastal communities are uniquely vulnerable to sea-level rise and severe storms such as hurricanes. These events enhance the dispersion and concentration of natural and anthropogenic chemicals and pathogenic microorganisms that could adversely affect the health and resilience of coastal communities and ecosystems in subsequent years. The U.S. Geological Survey has developed the Sediment-Bound...

Machine learning models of arsenic in private wells throughout the conterminous United States as a tool for exposure assessment in human health studies
Arsenic from geologic sources is widespread in groundwater within the United States (U.S.). In several areas, groundwater arsenic concentrations exceed the U.S. Environmental Protection Agency maximum contaminant level of 10 μg per liter (μg/L). However, this standard applies only to public-supply drinking water and not to private-supply, which is...

Gordon, Stephanie; Jones, Daniel K.; Blazer, Vicki S.; Iwanowicz, Luke R.; Williams, Brianna; Smalling, Kelly Changing climate drives future streamflow declines and challenges in meeting water demand across the southwestern United States
Society and the environment in the arid southwestern United States depend on reliable water availability, yet current water use outpaces supply. Water demand is projected to grow in the future and climate change is expected to reduce supply. To adapt, water managers need robust estimates of future regional water supply to support management...
