How Safe is Safe?
A Water Engineer's Perspective on Water and Public Risk
Bruce M Thomson, Ph.D., P.E.
Professor Emeritus and Research Professor
Department of Civil Engineering
Department of Civil Engineering
University of New Mexico
Life is filled with all sorts of
risks, some are voluntary like rock climbing and smoking, while others are
involuntary like breathing the air and being struck by lightning. The
first canon in the professional engineers’ code of ethics states that engineers
“shall hold paramount the safety, health and welfare of the public” but it
gives no guidance on what level of safety is expected. Achieving zero
risk for most activities is virtually impossible, so what are acceptable levels
of risk and who makes those decisions? Water poses both voluntary and
involuntary risks to humans. Two of the most recognized involuntary risks
are health risks from contaminants in drinking water and threats to life and
property from flooding. This talk will discuss what level of risk has
been determined to be acceptable for each situation, how this determination was
made, and consider some of the factors that may influence whether the goal is
being met and at what cost.
Then, after we’ve all consumed an
adult beverage or two, we’ll head home and test the transportation risks on the
Albuquerque road system.
Bruce Thomson is Professor Emeritus and Research
Professor in the Department of Civil Engineering at the University of New
Mexico. He served as Director of UNM’s Water Resources Program from 2005
to 2013. He has recently been re-elected to a 6 year term and is
currently Chair of the Board of Directors of the Albuquerque Metropolitan
Arroyo Flood Control Authority (AMAFCA). He has been at UNM since the
late Pleistocene epoch and is among the last practicing engineers in the state
who still knows how to use a slide rule.
