Environmental Geoscience
Hydrology and Ecohydrology
EAPS environmental geoscience faculty research includes studying the movement and quality of water in the hydrologic cycle, as well as anthropogenic impacts on watershed sustainability.
Environmental Chemistry
Studying the chemical processes that couple the lithosphere, hydrosphere, biosphere, and atmosphere, and their impacts on human activities and the environment, is the focus of select EAPS faculty and students.
Soils and Sediments
The weathering and erosion of soils, and how these processes support and change life on Earth, is a key research theme for our environmental geoscience faculty.
Environmental Biogeochemistry
Environmental geoscience faculty and students conduct various experiments that help further the study of the chemical, physical, geological, and biological processes and reactions that govern the composition of the natural environment.

Bubbling methane emissions caused by ice-free days in Arctic lakes
07-07-2020
Purdue EAPS scientists have found that the amount of methane being released by Arctic lakes is increasing and lake emissions are projected to significantly rise due to melting in the region.
'Carbon Farming' Could Make US Agriculture Truly Green
06-24-2020
New federal legislation may create positive and lasting environmental changes. Professor Timothy Filley "has met with members of the Senate committee working on the US carbon farming legislation. He hopes that the new bill will encourage more farmers to protect their soil and perhaps make a bit of a dent in climate change."

New Study Finds Nitrogen Availability Affects the Evolution of Future Carbon Sinks in Northern Eurasia
07-29-2019
A new study coauthored by an EAPS professor has yielded an interesting result – enhanced nitrogen availability from permafrost degradation, the abandonment of agricultural land, and atmospheric nitrogen deposition may account for 30-50% of the carbon sink projected for Northern Eurasia in the future.
