"The sprayed Bauxsol was "ineffective," Kline said, because it failed to penetrate much below the surface and did not migrate uniformly throughout the fill. He also said the application process requires more water than can be readily supplied.
Kline said Bauxsol lessened the acidity of only two of 12 ground-water monitoring wells on the test site. In those two wells, metal concentrations, though reduced, remained "significantly above" water quality discharge criteria. He said sulfate levels continue to be elevated at about 3,000 parts per million, against a targeted max of no more than 250 parts per million."

From the above comment by Kline, it seems that he knows so much in detail that the rest of the market does NOT. And yet in response to the ASX query, VTI says it sees no evil, hear no evil and therefore can say no evil.

Cheers.
