Well, you are in a controlled area with a limited population. A WWTP has t=
housands of gallons of supernate in up to 12 separate beds all drying at di=
fferent rates. The drying area covers about 2.t acres at a depth of about =
3 feet. We would have to apply so much tea that decanting the beds would p=
rove financially unrealistic. It would be a colossal committment of water =
that is at a premium here.

I approached a feed lot with a huge odor problem and suggested ACT for odor=
 control. Unfortunately, I did not know of the work you are doing. They d=
idn't go for it and even when I offered a free test run of two months, were=
 unmoveable. The city finally closed the operation down because there were=
 so many compaints about the smell.

Odor is tough to quantify. There are meters that can measure range and mag=
nitude of odor and they are used in WWTP mitigation. So outside of a speci=
fic closed area that can be controlled, I still have some misgivings about =
making any kind of odor control statement and tea. In my experience, spray=
ing on a vinyard, the workers did notice the sweeter smell of the tea but t=
hey were used to spraying fungicides so anything would have been a relief. =
 

I have a user spraying tea on turf for dog urination problems and charting =
the results. He says his neighbors like the smell of the tea when he uses =
it but it dissipates quickly. However great noseometers may be, they are u=
nreliable when trying to get people to spend money to remove odors.

Good luck with your work. If you could send me some better info as to rate=
s, I will try to get a test lined up at our local zoo.

  Odors in zoo enclosures ARE effectively controlled. Odors in tiger
  and lion transfer trucks with wooden floors are controlled for over a
  month.

  Asian elephants are a bit more difficult but monthy application of 25
  gallons of raw tea per thousand square feet is successful. Not
  biosolids, but successful oder control! All treatments were in
  acceptable range for bacteria in tea, fungal levels don't seem to
  have any relevance.

  A highly bacterial product is currently being marketed to zoo
  operations with great success.

  Experiments with horse rings and small cattle operations are being
  conducted.

  No science just results from "odorphobes" and persnickety noses.
