New study backs up sludge findings

11/11/2010
The State of Missouri’s Environmental Protection Agency and Department of Health have issued the findings of a new report into the presence of hexavalent chromium on farm-land in four counties. It concludes that chrome VI is present on the land, but not at a high-enough level of concentration to present a health risk to local people.

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.
