Annual Trash Data Dive
Who and What:
The State Water Resources Control Board’s Office of Information Management and Analysis will be hosting an annual immersive Trash Data Dive where data scientists work alongside trash experts, municipalities, policy writers and others to attempt to inform how and where trash is generated, transported, and deposited. The 2019 event will continue to build off the 2018 data dive summarized below.
Goals and Objectives:
The overarching goal of these annual data dives is to construct an understandable, credible statewide picture of our current trash management situation. Specifically, develop a trash management picture informed by open and accessible data, to identify and understand trends, data gaps, and priorities. This can best be accomplished through data visualizations and stories which can inform and direct statewide monitoring design, implementation, and reporting.
Our specific ongoing goals and objectives include:
- To gain better insight into the trash life cycle and how it is impacting our waters (e.g., Where is it coming from? How much is in our waterways? Are Best Management Practices (BMPs) working? Where are the hotspots? How much trash is making its way into the ocean?).
- To obtain a better understanding of data standards, schema, and collection methodologies necessary to use trash monitoring data effectively.
- To collaborate across multiple disciplines and sectors to better understand the issue as a whole.

2018 - Inaugural Trash Data Dive
November 16, 2018
2018 Trash Data Dive Summary
On November 16, 2018, the State Water Board’s Office of Information Management and Analysis held the first ever 2018 Trash Data Dive (TDD). The TDD was convened at the San Francisco Estuary Institute, located in Richmond, California. It was well-attended by over 80 attendants and included participants from all over California to discuss the opportunities to address entrenched problems with respect to trash-related information. Representatives from Regional and State Water Boards gathered together with those from other state agencies, non-profits, municipalities, private consultants, and the interested public to develop new concepts and visualizations using available trash data as collated by the event organizers.
Ambassadors were selected prior to the TDD to represent knowledge about trash from a variety of different aspects. These included government agencies that serve both regulatory and regulated purposes, as well as research organizations and NGOs. Each ambassador was asked to give a 3 minute elevator pitch to describe what they do and what questions they were interested in having answered. In addition, ambassadors were polled before the TDD to develop a list of challenge questions for the participants to ponder going in to the event. The first set of TDD presentations, offered by the TDD Ambassadors representing their various sectors, is available below in the ‘Opening Presentations’ section.
Challenge questions were used to identify six areas of interest based on different sectors and included Marine Debris, Public, California Tobacco Control Program, Machine Learning, Municipal, and Regulation. Posters were created to describe each sector and identify the pertinent questions. Ambassadors were assigned a posters to stand next to and answer TDD participant questions in a “speed dating” round.
This gave the TDD participants the opportunity to interact with each other and determine which questions were most relevant to themselves and develop groups to identify the data necessary and the desired visualizations. Once groups were formed, they split out into different areas of the building to begin work on formulating ideas.
Participants detailed concepts spanning the gamut, from identifying plastics in multiple environments, to tobacco-pollution-focused problem-solving, to ideas for addressing trash among the homeless and overburdened communities, to a “power portal” designed to gather and distribute heterogeneous data types. The ideas generated and the opportunity for networking among like-minded individuals across many disciplines made this event valuable for the project team and participants. Among the many Contestant Presentations in the 2nd set of presentations below were a number of integrated and constructively imaginative data visualizations of some commonly occurring trash stories. More detailed descriptions of the process and project ideas and concepts are available.
