If there are any results from this experiment, they haven't been published, or at least I can't find them if they were. I'm guessing that nothing was done to follow up, but that's just a guess.
Who was in charge in 2005? Hmmmm....
Anyway, evidently they have been using this on farm fields for a couple of decades. I'd be interested in knowing if they still do. I know there was a big flap made about Mexican farmers using human waste as fertilizer some time back.
"A U.S. government study reported in May, 2014 in Environmental Health News
found traces of prescription drugs and household chemicals deep in the soil as a result of a couple of decades of use of biosolids as fertilizer. Researchers, including hydrologists for the U.S. Geological Survey, tested an eastern Colorado wheat field that used treated sludge from a Denver sewage treatment plant. Chemicals in antibacterial soaps, cleaners, cosmetics, fragrances and prescription drugs such as Prozac and Warfarin not only persisted in the topsoil, but migrated downwards.
The study detected ten chemicals in the soil at depths between seven and fifty inches eighteen months after the sludge application. Other studies have found hormones, detergents, fragrances, drugs, disinfectants, and plasticizers in treated sludge used as fertilizer. But this is the first study to show how they can persist and move in soil. The antibacterial compound triclosan,
which is used in soaps, toothpastes, and cosmetics, was found at the highest concentrations in the deep soil. The U.S Food and Drug Administration is concerned that triclosan and other antibacterials could be contributing to antibiotic resistance. It has also has been linked to altered thyroid hormones and estrogen-related reproductive effects."
