Janet Gordon Hering (born 1958) is the former Director of the Swiss Federal Institute of Aquatic Science and Technology and Professor emeritus of Biogeochemistry at ETH Zurich and EPFL (École Polytechnique Fédérale de Lausanne).

Hering was elected a member of the National Academy of Engineering in 2015 for contributions to understanding and practice of removal of inorganic contaminants from drinking water.

[4] Her supervisor, François Morel, described her research as "elegant work on the surprisingly slow kinetics of some reactions between trace metals and organic complexing agents in natural water".

[5] She described the aquatic chemistry associated with the preparation of Aquil, an artificial algal culture, and the coordination of transition metals in seawater.

[1] Hering joined the Swiss Federal Institute of Aquatic Science and Technology (EAWAG) as a research fellow.

[13] By monitoring the amount of arsenic at various positions downstream, Hering found that the concentration remained constant, but the oxidation state changed.

[10] The dusty lake bed results in large (> 10 μm) particles of high arsenic content airborne dust that can travel far and be inhaled.

[10] Hering worked closely with the Los Angeles Department of Water and Power to mitigate the arsenic in their watershed.

[19][20] She gave evidence to the United States Environmental Protection Agency Ad Hoc Subcommittee on Arsenic Research and served on the Science Advisory Board.
