Will other brands accept wastewater test reports that are carried out in accordance with the ZDHC Wastewater Guidelines?
Having a single expectation for wastewater quality for the supply chain makes it easier for chemical suppliers to understand their customer’s needs and conform to the ZDHC Wastewater Guidelines. It is the explicit goal and expectation of ZDHC and its contributorship that the tests are accepted by everyone. That makes it possible to reduce the burden by not requiring individual, customised sampling and testing methods, or reporting limits.
