Map of U.S. Geological Survey PFAS study areas. Specific points indicate: 1) Surface water and field studies (teal circles), 2) PFAS in tapwater studies (black circles), 3) PFAS in groundwater studies (orange circles), and 4) Sites where atmospheric samples were collected (yellow triangles).
Brianna Williams
Brianna is a geographer working with the New Jersey Water Science Center Integrated Hydrology Investigation Team
Brianna is a member of the Environmental Health Mission Area’s geospatial Core Technology Team (CTT), and currently resides in Tucson, AZ. Her team utilizes landscape and point source variables to understand what is happening in water bodies and how that might impact the environment and human health. Some of these projects include analyses for endocrine disrupting compounds in the Chesapeake Bay watershed, aquifer contamination nationwide, and Harmful Algal Blooms offshore and in lakes and streams. Brianna began at the USGS in 2011 as a Pathways Intern in the Eastern Geographic Science Center and joined the NJWSC in 2017. Since joining the bureau she has had the opportunity to participate in a variety of projects including field work in Micronesia, stormwater best management practices research, cartographic support for science centers and groups, and outreach to high school students.
