New study backs up sludge findings
11/11/2010
A July 2009 study had already found that there was no link between tannery sludge—the source of the chrome VI—and health issues local people were suffering. The new government study draws the same conclusion. The federal Environmental Protection Agency None has put the limit of chromium VI at 86 parts per million. Missouri authorities took 600 samples of soil and water from the four counties and found that none of them exceeded that limit.
A tannery at St Joseph, Missouri, now under new ownership, had sold sludge to local farmers as fertiliser.
