Matthew S. Landis

Title: Research Environmental Health Scientist

EPA Division: Human Exposure and Atmospheric Sciences Division

EPA Branch: Environmental Characterization and Apportionment Branch

Matthew’s current research focuses on the impact that hydraulic fracturing for fossil fuels has on air and drinking water resources. As a principal investigator in the national hydraulic fracturing research study, Matthew is leading the development and implementation of a source apportionment study investigating the impact of hydraulic fracturing flowback and production waste water discharges on public drinking water supplies in Pennsylvania.

As the NERL atmospheric mercury research principal investigator, Matthew continues to look for opportunities to build upon the world class research conducted by NERL. As the mercury research program winds down, he has refocused his efforts to publish the results of recently completed research studies. These studies evaluate the impact of specific atmospheric mercury sources to wet and dry deposition, investigate long range atmospheric transport, and improve understanding of dry deposition processes.
