Steve:

Does the compost also need to be tested? Are there guidelines for compost =
inputs? It seemed when I read the report that additives to the compost wer=
e acceptable but not acceptable if added to the tea. What you indicate bel=
ow is great. It should be possible to test two independent batches and I w=
ouldn't even mind having to test once per year. However, we are talking ab=
out certification for organic use aren't we? Or is this for general distri=
bution of ACT?

  Dennis -

  I will try to reply with the limited information
  available.

  Here is the section from CTTF:

  "Compost tea made with compost tea additives can be applied
  without restriction if the compost tea production system
  (same compost batch, additives, and equipment) has been
  pre-tested to produce compost tea that meets the EPA recommended
  recreational water quality guidelines for a bacterial indicator of
  fecal contamination (US EPA, 2000). These indicators and the passing
  criteria are Escherichia coli (126 CFU/100ml) or enterococci
  (33 CFU/100ml). At least two compost tea batches must be tested
  using accepted methodology (APHA-AWWA-WEF, 1999; US EPA, 2000),
  with the average population of indicator bacteria across compost
  tea batches used as the measurement of passing."

  I know you said that you can read this yourself.

  All I can add is that the indicators come from EPA
  standards, as noted above and in the citations.

  Dr. Patricia Millner with USDA-ARS is an expert on
  these matters and provided the pertinent EPA standards.

  I don't have anything more to add on CTTF, Dennis.

  Feel free to contact me off list if you wish.

  Best wishes,
  Steve Diver
