Anna Deetz-Boetsma

Anna is the Supervisory Hydrologist of the Discrete Water Quality Observations Program with the New Jersey Water Science Center. Anna is primarily involved with surface-water-quality data collection, review, and dissemination.  Anna also serves as a GIS specialist within Water Quality Observations Program assisting in geospatial analysis, interpretation, and display. 

As a Hydrologist with the USGS, Anna has had the opportunity to work on a wide variety of water-quality related projects.  Early in her career, she participated in a study of long-term water-quality trends in New Jersey.  In the field, Anna co-lead a field effort to collect and analyze the effects of Hurricane Sandy on coastal and marine sediments.   She also co-authored the New Jersey Water Science Center’s review and analysis of Hurricane Sandy data.  

As the Supervisory Hydrologist of the Discrete Water Quality Observations Program, Anna has played varying roles on teams studying emerging contaminant issues related to PFAS, Harmful Algal Blooms (HABs), microbiological contaminants, and microplastics. 

In addition to her water-quality work, Anna is part of a team that developed a comprehensive water quality model for the Mohawk River basin as a collaborative effort with the New York Department of Environmental Conservation (NYDEC).  She was also involved with a coastal flood inundation mapping initiative for the New Jersey Tide Telemetry Network that will produce flood inundation maps for the entire coast of New Jersey based on ADCIRC modeled coastal storm data correlated to USGS tide gages.

Estrogen equivalents of surface water and smallmouth bass estrogenic biomarker data in New Jersey, 2016-2017

The data were gathered as a preliminary assessment of estrogenicity under base-flow conditions at over 100 sites (lakes and streams) throughout New Jersey followed by more targeted sampling of smallmouth bass at nine sites with varying levels of estrogenicity. In 2016, 102 sites (lakes and streams) for the preliminary estrogenicity assessment were selected utilizing compiled results of previous mo

Reconnaissance of surface water estrogenicity and the prevalence of intersex in smallmouth bass (Micropterus dolomieu) inhabiting New Jersey

The observation of testicular oocytes in male fishes has been utilized as a biomarker of estrogenic endocrine disruption. A reconnaissance project led in the Northeastern United States (US) during the period of 2008–2010 identified a high prevalence of intersex smallmouth bass on or near US Fish & Wildlife Service National Wildlife Refuges that included the observation of 100% prevalence in smallm

Documentation and hydrologic analysis of Hurricane Sandy in New Jersey, October 29–30, 2012

In 2012, a late season tropical depression developed into a tropical storm and later a hurricane. The hurricane, named “Hurricane Sandy,” gained strength to a Category 3 storm on October 25, 2012, and underwent several transitions on its approach to the mid-Atlantic region of the eastern coast of the United States. By October 28, 2012, Hurricane Sandy had strengthened into the largest hurricane ev
