To support the implementation of the ZDHC Wastewater Guidelines in value chains and to ensure a consistent level of quality for the wastewater and sludge test data submitted in the ZDHC Gateway – Wastewater Module, Stichting ZDHC Foundation (ZDHC) has established a provisional laboratory acceptance process (Provisional Laboratory Acceptance Process). This process has been developed to enable laboratories to conduct testing and submit data on behalf of suppliers to the ZDHC Gateway – Wastewater Module.

ZDHC is working on finalising a definitive “Laboratory Acceptance Process 1.0” (working title) in 2018, taking into account learning from the provisional acceptance process. Provisionally Accepted Laboratories will be expected to meet the final criteria for full laboratory acceptance under this final process once established.

In the meantime, ZDHC has granted each of the laboratories listed below a PROVISIONAL acceptance for wastewater and sludge analysis in connection with the ZDHC Gateway – Wastewater Module. The grant of this provisional status followed a review by ZDHC of a number of laboratories owned and/or operated by these organisations according to the ZDHC Provisional Laboratory Acceptance Process. The provisional acceptance status is granted exclusively for the purposes of submitting data to the ZDHC Gateway – Wastewater Module. The provisional acceptance status for each laboratory listed is valid for one (1) year and subject to the conditions, including ZHDC required improvements, which are communicated to each laboratory as part of this process.


By requesting access to and downloading this list I understand and agree to the following:

1) The laboratories on this list are ‘provisionally’ accepted by ZDHC. This acceptance status may change and does not imply that any one laboratory on this list will be granted full acceptance status.

2) This list is an indication of those laboratories that have been granted Provisional Accepted Laboratory Status by ZDHC. This indicative list which is provided for information only may become out of date very quickly and does not represent the definitive list of provisionally accepted laboratories which is available only in the ZDHC Gateway – Wastewater Module.

3) The quality and service for wastewater testing against the ZDHC Wastewater Guidelines may vary depending upon the specific (non-public) conditions for improvement for each provisionally accepted laboratory.

4) ZDHC accepts no liability whatsoever in connection with any damages or losses that result from reliance on this list. Further, ZDHC accepts no liability for discrepancies, change of status, or other parameters that might have arisen between the time of publication and the time of use of this list.
