The Duff & Phelps Charitable Foundation is a supporter of American Rivers work to protect wild rivers, restore damaged rivers and conserve clean water for people and nature. We will be celebrating this partnership by cleaning up our local rivers and communities through their National River Cleanup® program. Join the Duff & Phelps Cleanup Challenge to help reduce and prevent litter from reaching our rivers and streams from your own community. Together we can keep our waters clean and healthy for people and wildlife.

This year we’re hosting a virtual cleanup! Join the Duff & Phelps Community Cleanup Challenge to help reduce and prevent litter from reaching our rivers and streams from your own community. Together we can keep our waters clean and healthy for people and wildlife.

Employees are invited to work individually or with their families to pick up litter and dispose of it before it contaminates our rivers. Employees will use a mobile app, Litterati, to track their litter collection effort and provide important data to help map litter and types of litter in your community and waterways. This event is open from November 13-November 22.

Frequently Asked Questions

How do I take photos?

Open the app and click on the blue camera icon in the bottom right corner to take and upload a photo of trash. To take clear pictures, wait 3 seconds for your camera to focus. We recommend positioning your phone at least 1 meter from the ground and wait 3 seconds for your camera to focus.

How do I tag litter?

The tagging feature allows users to accurately label images of litter. Use the Tagging feature to provide detail and insight on each piece of litter you collect. Add 1 – 3 tags per image. Ideally, each litter item will have tags representing three different descriptions (object name, material and brand). For example, if you find an aluminum can of soda, you can apply unlimited tags to your photo with “soda can” and/or “can,” “aluminum” and tag the brand. Watch the Data, AI, Tagging and Gallery video for more info on how to tag litter in the app.

Can I use the app when I am off the grid or have limited cell service or phone signal?

The app does not require mobile data or a Wi-Fi connection to capture photos within the app. Mobile data or a Wi-Fi connection is required to upload the photos to the Litterati database.

If you do not log out or delete the app, any photos captured will remain stored in the app until you have service again. Once you are in service, open the app and your photos will upload to the cloud server.

Please note: Your litter will only count towards the challenge if it is uploaded by the end of the challenge period. Upload all photos to Litterati by November 22, 2020.

Can I take photos in the app without cell service and upload them to the app later?


Can I take photos outside of the app and upload them to the app later?

Yes, photos can be uploaded to the app while in camera mode. To do this, click on the blue camera icon like you would to take a picture. In camera mode, in the bottom left corner, click on the picture icon, then select the photo(s), click done and upload. If your phone’s camera settings allow photos to have geotagging, then the photo’s location will be automatically included in your upload.

How do I prevent the app from draining my battery?

The main cause for the battery drain is due to the app’s location services and GPS accuracy mode. Before participating, we recommend:

  • Ensuring your phone battery is fully charged. If you are going somewhere for a few hours or will be using your phone’s maps or GPS, bring a charging cord or a portable charging device.
  • Closing all other apps when using the Litterati app. Change your phone settings to “power saving mode.”
  • Changing your photo uploading settings in the app to Wi-Fi only by going to your “Profile.” Under “Settings,” select “upload via Wi-Fi only.”

What happens if the app crashes and how do I prevent it?

If your app crashes while uploading photos, your collected data and photos should remain unharmed. While your photos are uploading, wait and do not exit out of the app until the upload finishes. Avoid switching between multiple apps while using Litterati.
