Re: dioxin fingerprints

  Dioxins (the family) are everywhere folks (coming out of long lurk mode).
  Not just from the chlorine used for treatment (although I personally prefer
  that to ozone for its 'shelf life' contribution to water purity). Add air
  sources (autos, fires, etc).
  But even if there were residual dioxin in tampons and TP -- get real!
  Tampons Are Not Supposed to be FLUSHED! And TP is not anywhere near the
  volume that would affect quality. At those levels, the pathogens are a hell
  of a lot more dangerous to public health, anyway.
  And why would landfill leachate be going directly into a publicly owned
  waterwater treatment plant? Why would it not be subject to pre-treatment
  requirements like any other "Industrial" source (even if the landfield were
  publicly owned) if it were that "hazardous"?
  Most large-scale pulp mills have their own treatment (WW and Sludge) .. and
  besides, sludge (pulp mill or otherwise) shouldn't be going into a Muncipal
