Welcome to CDM Smith.

Charles E. Schaefer, Jr., PhD

Principal Environmental Scientist

Dr. Charles Schaefer is an en­vi­ron­men­tal sci­en­tist and the director of CDM Smith's Bellevue, Washington research and testing laboratory. His research ex­per­tise includes pore-scale dif­fu­sion and mass transfer processes, in situ biore­me­di­a­tion, treat­ment of emerging con­t­a­m­i­nants including perfluorinated compounds such as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) and elec­tro­chem­i­cal treat­ment of drinking water. Charles has served as a prin­ci­pal in­ves­ti­ga­tor on several research grants, many of which have focused on chlo­ri­nated solvents in bedrock systems. He has authored over 40 peer-reviewed papers and is an active member of the In­ter­state Tech­nol­ogy and Reg­u­la­tory Council (ITRC). In addition to his research, Charles also serves as a tech­ni­cal con­sul­tant on several federal and private sector projects for CDM Smith, many of which address chlo­ri­nated solvents in complex ge­o­log­i­cal settings.

Which one of CDM Smith’s core values do you identify with most and why? While the core values are all im­por­tant, ex­cel­lence is the one that I identify with most because it does not come easily or nat­u­rally. It requires intent, effort and per­sis­tence. I feel that I can never truly attain it, but must also try to get it.

What’s some­thing you enjoy doing on your day off? Spending time with friends and family.

What’s some­thing that people might be sur­prised to know about you? I was once on TV as a con­tes­tant on The Price Is Right. 

Why CDM Smith? It’s a company where you can work on in­ter­est­ing, chal­leng­ing, high-profile projects that have a positive impact on clients and com­mu­ni­ties. CDM Smith is filled with great people who phave a lot to offer and the depth of re­sources makes it all the more fun to tackle big, complex chal­lenges.

  

What’s your favorite part of your job? Seeing our teams do ex­cel­lent work that results in clients coming back to us for help with their next chal­lenge. I love wit­ness­ing that positive re­in­force­ment and synergy build with each as­sign­ment.


What’s some­thing you enjoy doing on your day off? Going on a hard bike ride with friends in the morning and then put­ter­ing around the yard for the rest of the day. I’d cap it off with a great dinner or evening on the beach.

 

What’s some­thing that people might be sur­prised to know about you? I was once an avid com­pet­i­tive sailor and competed in the 1988 U.S. Olympic Trials.
