The SaniPath Exposure Assessment Tool: An Integrated Project Management, Data Analysis, and Visualization Platform

S. Raj, Y. Wang, A. White, N. Kishore, C. Siesel

UNC Water and Health Conference (October 2018)

Suraja Raj presented a poster at the UNC Water and Health Conference in October, 2018, highlighting new developments related to the new SaniPath Tool. The SaniPath Tool examines human exposure to fecal contamination in low-resource urban settings. It provides guidance for primary data collection, automated exposure analysis, and results visualizations that are accessible to people from a range of scientific backgrounds. This poster describes the development of a tool that allows users to plan a SaniPath deployment, set up and manage mobile data collection, analyze results, and generate reports. The tool guides users through steps of implementing the tool–from planning to data analysis. The tool is composed of a project planning and management interface, mobile data collection and data repository, and a data analysis and visualization dashboard. The tool can be customized to suit context-specific data collection needs. The SaniPath Tool is built on an integrated system of existing open source technologies and a tailored project management interface. It guides users through project configuration, training, and deployment by automating the customization and analysis processes. The Tool also uses an open source mobile data collection software, KoboToolbox (KT), which provides the backbone of data collection and storage. Data is collected via downloadable mobile forms used on Android devices and is uploaded to KT, which is paired with Enketo for online web data entry or editing. The tool automatically retrieves data from KT and generates exposure assessments for each study site and exposure pathway. Users can view and analyze the collected data, access data visualizations, and create a draft final report. The services are deployed on Amazon Web Services (AWS) infrastructure and backups are stored in S3 buckets for redundant data storage. The SaniPath Tool is an innovative use of mHealth in the WASH sector and can serve as an example of how open source software can be used to synthesize and analyze complex information and encourage public health evidence-based decision-making about urban sanitation investment.

Assessment of Exposure to Fecal Contamination in Informal Settlements and Formal Neighborhoods of Siem Reap, Cambodia

J. Green, S.Raj, Y.Wang, D. Duong, M. Yakushima, S. Chhun, H. Yakubu, J. Michiel, J. Wicken, CL. Moe

UNC Water and Health Conference (October 2017)

At the 2017 UNC Water and Health Conference in Chapel Hill, North Carolina, Jamie Green presented a poster on an assessment of Exposure to Fecal Contamination in Informal Settlements and Formal Neighborhoods of Siem Reap, Cambodia. The CGSW’s Sanipath Tool was used to assess the risk of exposure to fecal contamination in 5 environmental pathways in 5 neighborhoods (3 formal and 2 informal settlements). Overall, there were large variations in exposure risks within formal neighborhoods and informal settlements. Results show that raw produce posed one of the greatest risks of exposure to fecal contamination across all five neighborhoods (100% of adults exposed to dose ranging from 7.59E05 to 1.78E07 CFU/month from produce). Participants in all neighborhoods reported bottled water and well water as main sources of drinking water, while few reported drinking municipal water. No E. coli was found in municipal water, while bottled water and well water had moderate amount of E. coli. The lowest dose of exposure for floodwater was found in the only neighborhood with a drainage system (4.79E02 CFU/month). Results from this study provide evidence for decision makers to prioritize efforts to reduce exposure to fecal contamination in Siem Reap.

Public Health Risks Associated with Unsafe Fecal Sludge Management in Accra, Ghana

Habib Yakubu, UNC Water and Health Conference (October 2017)

At the 2017 UNC Water and Health Conference in Chapel Hill, North Carolina, David Berendes and Suraja Raj presented on behalf of Habib Yakubu. Both colleagues discussed the rationale, design, and results of the SaniPath Tool, a tool which evaluates public health risks from unsafe fecal sludge management (FSM) in low resource urban neighborhoods around the world. In this presentation, the results from four representative neighborhoods in Accra, Ghana were shared. The four neighborhoods were classified using a score scale into “very poor”, “poor”, “moderate” and “good” sanitation neighborhoods. Behavior survey and environmental sampling data showed a general trend of fecal exposure that followed the classification of neighborhoods. However, produce had the greatest risk of exposure to fecal contamination regardless of the classification of the neighborhood. Overall the study found that unsafe FSM can lead to exposure to fecal contamination irrespective of where you live.

Pathogen flows: Applying public health principles to urban sanitation – A synthesis of current research, tools and approaches that add the public health perspective back into urban sanitation

CL Moe

World Water Week (August 2017)

At the 2017 World Water Week conference in Stockholm, Sweden, Dr. Christine Moe participated in a presentation that examined the intersection of urban sanitation and public health. Dr. Moe explained the rationale, design, and results of the SaniPath Tool and how public health principles are incorporated to assess risk of exposure to fecal contamination in urban low-income communities. The presentation discussed the value of incorporating public health principles in sanitation tools and how results can be used to influence policy. This event covered “solid and liquid fecal wastes, in sewered and unsewered settings” and aimed to focus on how pathogen flow factors could be incorporated into sanitation action and thinking.

Translating Sanitation Tool Results to Policy

Emory University, TREND Group, Ghana, Center for Science and Environment (CSE), India, Center for Study of Science, Technology and Policy (CSTEP)

40th WEDC International Conference (July 2017) – Side Event

At the 40th WEDC conference in Loughborough, UK, Habib Yakubu and Christine Moe of the SaniPath team hosted a side event with CSE, CSTEP, and TREND that allowed for sharing of experiences related to using sanitation-related tools and data to influence policy and development. The outcome was an engaging discussion about how to best use tools to influence policy by engaging policymakers and by considering how results of tools can inform evidence-based policy recommendations.
