We’re sending our very best wishes to Dr. Christian White as he leaves the lab for his new postdoctoral role at Argonne National Lab. Christian’s PhD research explored the genomics and community roles underlying anaerobic ammonium oxidation and associated nitrogen cycle pathways; the results offer significant contributions to both fundamental microbial ecology and applied water […]
Thanks, Dr. Antell
This summer, we wished Ned Antell a bittersweet “bon voyage” as he completed his PhD and began his new position as a staff scientist with Remedy Scientific. His massive impact on the lab will be reflected in our research for years to come–and is already evident in a variety of publications, including his recent paper […]
PFAS Regulations Announced by the EPA
Today, the EPA has announced final regulations on six different PFAS species (PFOA, PFOS, PFHxS, PFNA, HFPO-DA/GenX, and PFBS) in drinking water. The rule sets enforceable levels for these PFAS in drinking water. Water systems will now be required to begin monitoring PFAS, and must publicly disclose PFAS levels beginning in 2027. For more information, […]
Thanks, Dr. Tsou
Our own Katerina Tsou has completed her PhD and is off to her new position with AECOM. (We are cheering ourselves up by re-reading her newest publication, about PFAS release in stormwater and saltwater, here.) Congratulations, Katerina!
New publication: Interactions between anammox and DNRA bacteria across varying bioreactor nitrogen loading ratios
Anaerobic ammonium oxidizing (anammox) bacteria are key players in wastewater treatment and environmental nitrogen cycling. These microbes have complex interactions with other groups of bacteria, which affect overall nitrogen metabolism, especially when nitrogen sources vary. This study, led by graduate student Christian White, finds that bacteria performing anammox have a mutualistic relationship with bacteria performing […]
New publication: Using the TOP assay as a forensic tool for PFAS source apportionment!
Determining the source of per- and polyfluoroalkyl substances (PFAS) in the environment is complicated by their widespread use in consumer and industrial products and processes. This new study, led by graduate student Ned Antell, examines how the total oxidizable precursor (TOP) assay, which indirectly quantifies difficult to measure PFAS species, can enhance our understanding of […]
Thanks, Dr. Steffens
We’re devastated thrilled to wish our own Dr. Sophia Steffens well as she departs the group for her next scientific adventure. After completing her PhD and years of groundbreaking environmental and green chemistry research, she’s off to start her new role with BASF. We will miss you, Sophia!
EPA proposes new PFAS regulations
On March 14, the Environmental Protection Agency announced proposed drinking water regulations for six PFAS species (PFOA, PFOS, PFNA, HFPO-DA, PFHxS, and PFBS. These regulations are slated to be finalized by the end of 2023. See the announcement here: https://www.epa.gov/sdwa/and-polyfluoroalkyl-substances-pfas
