IDDE Training Videos
The following videos have been developed to assist in the training of municipal employees on how to identify and conduct IDDE sampling. These videos are currently in draft form and some information might be missing from them. We are in the process of finalizing the videos and will post the final versions as they become available. The draft versions are available for municipalities so they can start conducting their IDDE sampling. Please check back often as we are also working on additional videos that will be available soon.
