Hey Renn,
That seems very responsible and forward thinking of you to pursue this certification considering that you may one day need to stamp things where that type of work has been performed.
Personally, with a background in water, I have considered a few certs or licenses that I'd like to look into more "one day". For me, these include the PMP, LEED Accreditation, D.WRE, or Certified Water Professional (CWP) accreditations.
I would also like to go a whole different route and take more programming courses. This might not lead to a certification (and I wouldn't be disappointed if it didn't) - but there have been many times in my career where a task has been stalled due to my lack of knowledge in the world of R and Python and I've had to go bother a programmer for assistance.
