Heya!
 I happened to be at a water conference last week, unfortunately no ebmud folks were there.  That said, I have other friends :)
  Elizabeth from https://whollyh2o.org/ has contacts and would love to connect EWG with them!  I'll pass her info along privately.
Also I'd love to join the EWG! Is there an email list or slack or whatnot?
I'd also love to invite others if that's copacetic as well! :)
warmly,
ajay
