Leather Wastewater Guidelines Addendum Update

The latest update to the ZDHC Leather Wastewater Guidelines Addendum was made to improve the accuracy of testing and reduce the need for confirmation testing.

In tropical locations, naturally occurring organisms can be mistaken for faecal coliforms thereby increasing the possibility of a false-positive result in wastewater testing(1). By replacing the test for Faecal Coliform with an Absence/Presence test for E.coli, it improves the accuracy of wastewater testing and reduces the need for confirmation testing.

ZDHC makes the update based on information that was brought to light, expert advice and the decision of the Wastewater Council. The update will also be reflected in the ZDHC Wastewater Guidelines V2.0, and apply to all textile and MMCF wastewater.
