Organic Micropollutants in New York Surface Waters and Groundwater

2017 - present

In collaboration with colleagues from the Upstate Freshwater Institute, SUNY-ESF, and the New York State Federation of Lake Associations, we completed an exploratory study to evaluate the feasibility of establishing a citizen science program for monitoring organic micropollutants in New York inland lakes (see Shiru's article on this work). We are also collaborating with the Upstate Freshwater Institute to characterize the sources and fate of organic micropollutants in the Onondaga Lake-Three Rivers system in central NY.

In collaboration with colleagues from SU Earth Sciences and Maxwell School, we are investigating how hydrological processes and human activities drive the occurrence and transport of organic micropollutants in central NY watersheds.

In collaboration with USGS scientists at the New York Water Science Center, we are studying the occurrence and fate of organic micropollutants in onsite wastewater treatment systems and hydrologically connected shallow groundwater on Long Island, NY.

N-Nitrosamines and Their Precursors in Wastewater and Drinking Water

2016 - present

​We are collaborating with multiple water utilities and USGS to characterize the sources and fate of wastewater-derived N-nitrosamines and N-nitrosamine precursors during wastewater treatment and reuse.

In collaboration with Prof. Mark Krzmarzick at Oklahoma State University, we are studying the impacts of trace metals on the production of disinfection byproduct precursors by bacterial biofilms in drinking water distribution systems.

Photochemistry of Organic Matter in Acid-Impacted Lakes and Watersheds

2018 - present

In collaboration with Prof. Charley Driscoll at SU, we are studying the photoreactivity of organic matter in Adirondacks lakes and watersheds that are recovering from acid deposition while experiencing the effects of changing climate. We are especially interested in understanding the roles of photochemically produced reactive intermediates in contaminant transformation and biogeochemical processes. Check out Joseph's first article.

We are also collaborating with Prof. Fernando Rosario-Ortiz at CU Boulder to study the aquatic photochemistry of harmful secondary metabolites produced by freshwater and marine algal blooms (see our review article).

Substance Use Assessment by Wastewater Surveillance

2020 - present

Our group is part of the SARS2 Early Warning Wastewater Surveillance Platform (SARS2-EWSP) team led by SU, SUNY-ESF, and SUNY-Upstate. We developed an online SPE-LC-HRMS workflow to characterize substance consumption patterns and their relations to sociodemographics and COVID-19 prevalence in central NY sewersheds.

See Shiru's paper about our proof-of-the-concept study.
