The environmental PE exam is something many civil engineers wouldn't dare take because it involves more process related subjects and most civil engineers simply aren't environmental engineers. They are more broad based. In larger firms civil engineers may focus on water or wastewater. Passing the environmental PE exam is extremely useful for those jobs. Also, how many water resources and enviro civil engineers do structural and/or geotechnical projects? Probably very few. That was old school. Not today.hi - I'm still waiting on results for the April '08 Enviro...
if I'm unlucky (a distinct possibility given the unexpected emphasis of some of the exam - note: I discovered this site AFTER the exam and immediately realized how useful it would have been, so for those of you here, you're already one-up), I just wanted to give a shout-out that I'll be joining in this discussion for Oct '08...
On a side note: can anyone offer any comments as to why they chose the Env over the Civil (w/Env,Water Res PM)? I struggled with this decision, especially as someone who has moved to different states quite a bit, and not all states offer the exam (but most will at least recognize through comity, if I recall correctly). Sorry if this is a misplaced comment for this post, just trying to validate my decision to re-sit for the Env (if necessary) instead of giving the Civil a shot.
My decision to take the enviro exam was primarily because I did not want to study structural, transportation, geotechnical, construction, etc and would enjoy learning about the other enviro topics I don't practice (air, remediation, health & safety, etc.). Also, the enviro exam allows for superior performance in a subject to offset poor performance in other subjects. Finally, in my state there is no differentiation between a discipline -- it's a Professional Engineer license period. And I'm certain a civil PE passing grade does not mean you can do everything an environmental engineer does nor even all the subjects the civil exam covers (most general civil engineers don't go beyond land development and package treatment plant designs).
It also depends on your line of work -- the enviro exam passing grade will surely give someone the upper hand in water and wastewater projects as opposed to the civil exam. That's my take.
