Senior Engineer

Sustainability has been a central theme throughout my career. As an engineer, I particularly enjoy crafting approaches and tools to efficiently reduce chemical and energy inputs, guided by lessons learned from sustainability initiatives worldwide.

Cheryl Keenan provides a wide variety of support to ERG clients, with a focus on data analysis and visualization, sustainability, and environmental indicators. She is particularly skilled at analyzing datasets to find the trend or “story” that may not be apparent initially and using data visualization tools to clearly convey those stories to diverse audiences.

With over 20 years’ experience supporting all aspects of the U.S. Environmental Protection Agency’s Toxics Release Inventory program, Cheryl is one of the foremost TRI experts in the nation. Her work has included projects focused on development of the TRI annual TRI National Analysis, data quality, and analyzing data from TRI-like programs globally. She currently serves as a lead TRI trainer, delivering annual basic and advanced TRI training sessions to the regulated community, and as an EPA-credentialed TRI inspector, inspecting multiple facilities each year to confirm they are meeting their TRI requirements. She has also supported pollution prevention and sustainability efforts for other U.S. and international clients. In addition, Cheryl serves as the technical lead for management of environmental indicators in the “Land” theme area of EPA’s Report on the Environment. Other work includes conducting community-based training on minimizing lead exposure and management of external peer reviews of scientific and technical documents for EPA.

Cheryl holds a B.S. in mechanical engineering from Lehigh University and an M.S. in environmental engineering from Tufts University. Outside work, she enjoys hiking, biking, and raising and training puppies as their first step in becoming guide dogs for the visually impaired.
