Emily Tummons, Ph.D., Black & Veatch - Water Treatment Technology
CEE Seminar


Utilities are currently experiencing a heightened public interest in drinking water distribution system water quality and infrastructure related to the release of metals, in particular lead. This presentation will discuss recent high profile events that have brought this renewed public interest while highlighting actions utilities across the nation are taking in terms of operations, maintenance, and planning.  A case study will be presented highlighting how one Michigan utility conducted a risk assessment of its system related to lead and copper release. This discussion will include examples of lead pipe identification and replacement programs, including GIS asset mapping and additional field tools; distribution system water quality monitoring programs; flushing programs; desk-top, bench-scale, and pipe-loop testing corrosion experiments and water quality modeling; hydraulic modeling; and a review of compliance requirements for current and anticipated future Lead and Copper Rule (LCR) regulations.



Dr. Emily Tummons joined Black & Veatch in the Water Treatment Technology group in 2016 after completing her PhD in Environmental Engineering from Michigan State University.  Her dissertation work focused on the mechanisms of membrane-based separations of oil-water emulsions to gain insight into oil droplet behavior at the membrane surface.  She also earned her MS in Environmental Engineering from Michigan State University, and her BS in Biological Systems Engineering from Kansas State University.  Since joining Black & Veatch, she has been involved in projects around the country and overseas pertaining to corrosion control in the distribution system.  Along with corrosion control, Emily has been involved in bench-scale testing for various coagulants and oxidants, water quality modeling, and optimization studies for various water sources.
