  Jon, we are a little away from my area of expertise, and I fully
  acknowledge that dioxins and furans will find their way to the POTW.  I
  also acknowledge that organo-chlorine chemistry is going on there.  But
  I had not heard of any reference that dioxins will freely form in low
  orders of entropy without a lot more forced chemistry behind it.  Do
  you have a reference that says dioxins (or TCE) are actually *formed*
  in the wastewater stream?

  Same question.
