Systems and Sustainable Services
Susan Davis, Global Coordinator, Agenda for Change; Founder and Executive Director, Improve International
Community-focused water projects continue to lead to disappointing results for decades. What happens when something breaks? What happens when that latrine fills up? Who makes sure the water is safe, or the fecal sludge is treated and disposed of correctly? Most communities cannot maintain safe, reliable water or sanitation services without support from local government and the private sector. That’s where the systems strengthening approach comes in
Watershed level impact of septic systems on water quality in Metro Atlanta
Mussie Habteselassie, Associate Professor, Crop and Soil Sciences, Soil Microbiology, UGA College of Agricultural and Environmental Sciences
Septic systems are widely used in the southeast but their impact on water quality is not well understood to allow for their proper management at watershed level. This study investigated the impact of septic systems on water quality of streams in watersheds of metropolitan Atlanta in collaboration with the South Atlantic Water Science Center of United States Geological Survey. The impact of septic systems was isolated using multiple approaches that included targeted monitoring of fecal indicator bacteria and microbial source tracking markers as well as watershed scale modeling with the Soil and Water Assessment Tool. Twenty-four urbanizing watersheds impacted by a gradient of septic system density and land use characteristics were monitored for three years. Results indicated that density of septic systems and the proximity of septic systems to streams were significant drivers of fecal pollution in the watersheds. Moreover, the influence of septic systems was seasonally dependent.
Drinking water quality, food insecurity, and health outcomes in a cohort of infants and mothers residing in a community affected by El Niño flooding: Piura, Peru, 2015-2017
Carlos Culquichicon, MD, Emerge Piura, The Emerging Diseases and Climate Change Research Unit, Universidad Nacional de Piura / Miranda Delahoy, PhD, Environmental Health Sciences, Rollins School of Public Health

Miranda Delahoy recently completed her PhD in Environmental Health Sciences at Rollins. Her dissertation was entitled “Challenges in Reducing the Burden of Childhood Diarrhea in Peru” and addressed several factors associated with diarrheal disease in Peru, including rotavirus vaccination, climate change, El Niño events, sanitation, and water quality and access.
Investigating Novel Drivers of Leprosy Transmission: Where Do Unsafe Water, Sanitation and Hygiene Fit?
Jessica Fairley, MD, MPH, Associate Professor of Medicine, Division of Infectious Diseases, Emory School of Medicine, Rollins School of Public Health
Leprosy remains under recognized as a cause of significant morbidity in many regions of the world and incidence rates have not appreciably declined in well over a decade. Overwhelmingly, leprosy affects areas with low resources and high rates of poverty. Studies identifying the contribution of poverty-related factors to leprosy transmission such as neglected tropical diseases (NTDs) and unsafe WASH are lacking within the global leprosy research arena, stalling progress towards leprosy elimination. Our work in Ethiopia and Brazil investigates novel drivers of leprosy transmission such as parasitic co-infections that may influence the infectiousness of leprosy and unsafe WASH factors that may harbor viable Mycobacterium leprae. The goal is a multidisciplinary approach to leprosy control that may lead to strategies to effectively reduce transmission in highly endemic areas.
Water, sanitation and hygiene for the control of neglected tropical diseases: recent evidence and emerging approaches
Matthew Freeman, PhD, MPH, Associate Professor, Department of Environmental Health, Rollins School of Public Health
The World Health Organization has identified improvements to water, sanitation and hygiene (WASH) as critical for control and elimination of several of the so-called neglected tropical diseases, including trachoma, soil-transmitted helminths (STH), and schistosomiasis. There is ample observational evidence suggesting an impact of WASH on NTDs, but rigorous trials and effective interventions are lacking. These NTDs have been primarily addressed through preventive, population-based drug delivery. There is a need to not only understand the impact of WASH on NTDs, but to develop and evaluate effective interventions. Dr Freeman discussed recent evidence and emergent approaches to integrate WASH and NTD programming.
Beyond Construction: Theoretically-Informed Behavior Change Intervention Design for Increasing Latrine Use in Rural India
Presentation not available for viewing
Bethany Caruso, PhD, MPH, Department of Environmental Health, Rollins School of Public Health
Water, sanitation and hygiene (WASH) have important impacts on health and well-being. However, impacts may be limited if appropriate behaviors are either not sustained or practiced. In the WASH sector, there has been a consistent push for the development and delivery of technologies, like water filters, toilets, and handwashing facilities, with less effort and emphasis on the design and delivery of contextually appropriate interventions to change and sustain behavior. In India, for example, an ongoing, multi-billion dollar national campaign is ongoing to increase latrine coverage. Comparatively little effort and money has been used to understand barriers to use by all family members and encourage latrine use by all, which is low and inconsistent even among latrine owning households. In this talk, Dr. Caruso discussed the process, including mixed-methods approaches and application of behavioral theory, to develop and test an intervention designed to increase latrine use in rural, Odisha India.

WASH and Women: What does female involvement in water and sanitation mean and why do we care?
Kelly Alexander, MPH, Senior Learning and Influencing Advisor for CARE’s Water+ team
Goal 5 of the SDGs is gender equality and women’s empowerment and 6 is clean water and sanitation. Involving women in water and sanitation programming is considered the best way forward for sustainable WASH. But many development partners (and governments) do not know how to execute this in practice. Kelly will discuss CARE’s gender framework and present findings from a recent policy assessment and community-level qualitative research in the Solomon Islands.
Using molecular approaches to determine the composition and function of microbial communities in different environments
Chris Greening, PhD ,Lecturer, Head, Integrative Microbiology Laboratory, Monash University
A tremendous abundance and diversity of microorganisms inhabit natural environments worldwide. While many of these microbes perform critical ecosystem services, such as nutrient cycling, a subset are pathogens that compromise public health. In recent years, the development of cultivation-independent molecular approaches has revolutionized our understanding of the composition and function of microbial communities, including in the public health field. In this seminar, I will give an overview of the techniques used to (i) extract nucleic acids from different environmental samples, (ii) determine the relative and absolute composition of their microbial communities, and (iii) explore and validate the function of specific community members. These approaches will be illustrated by examples from my work investigating the composition and metabolism of microbial communities in soil, marine, and gastrointestinal samples. The techniques and insights provided are relevant for ongoing studies investigating the environmental transmission pathways and survival mechanisms of pathogens.
Nudges, Norms, and Enabling Technologies: New Approaches to Water, Sanitation, and Hygiene (WASH) Behavior Change.
Robert Driebelbis, PhD, MPH, Lecturer in Health and Hygiene, London School of Hygiene and Tropical Medicine
Improving water, sanitation, and hygiene (WASH) behaviors at the individual-and institutional-level remains a challenge in the health and development sectors. Traditional knowledge-based approaches to behavior change have resulted in limited improvements in practice. This presentation will focus on recent advances in our understanding of WASH behaviors and WASH behavior change, including recent advances in behavioral theory, the role of enabling and appropriate technologies is fostering sustained behavior change, and the application of “nudges” – environmental cues – to trigger intended behavioral outcomes.

A Randomized Controlled Trial of a Hospital-Based Hand Washing with Soap and Water Treatment Intervention to Reduce Cholera (CHoB17)
Christine Marie George, PhD, Department of International Health, Johns Hopkins School of Public Health
Household contacts of cholera patients are at a 100 times higher risk of developing a cholera infection than the general population. To initiate a standard of care for this high-risk population in Bangladesh, our research group developed the Cholera-Hospital-Based-Intervention-for-7-Days (CHoBI7), which promotes hand washing with soap and water treatment for the household contacts of cholera patients. In this seminar, the results of the randomized controlled trial of this intervention were presented.
Impact of Drinking and Cooking Water Mineral Contents on Kidney Health and Implications on Future Cardiovascular Disease.
Naser Titu, PhD Candidate, Environmental Health, Rollins Schools of Pubic Health
Drinking water salinity has contributed to potable water scarcity and high sodium intake in southwest coastal Bangladesh. High prevalence of pre-eclampsia and high blood pressure has been associated with drinking water salinity in this region. Managed aquifer recharge, a hydrogeological intervention to reduce groundwater salinity, is currently being promoted in this region to solve the drinking water crisis. This project examines the health benefits and risks of drinking water from managed aquifer recharge.

CGSW World Water Day 2016 – Flint Water: What Happens When Regulations Fail?
World Water Day is time for us to reflect and raise awareness about the global challenges of access to safe water for developing nations. As a community of scholars, we take this opportunity to educate our local Atlanta and Emory community and create dialogue around emerging and important issues in safe water that impact our world. This past year, we turned our attention to the water crises occurring in our own backyard – in Flint Michigan and other communities across America.
Using a series of short talks and a panel discussion, we explored the issues of water contamination in American drinking water supply through the lens of legal experts, public health scientists and medical practitioners. Our primary objective was to educate our audience and have an open dialogue regarding the intersection of water science, public health and US water policy. We also wanted to discuss the implications of various water contamination crises on our continued access to safe water in America – should we be worried?

CGSW World Toilet Day, 2015 Lessons Learned in Sanitation
A lecture and panel discussion with visiting sanitation experts from SWA, WHO, Bill & Melinda Gates Foundation, USAID and World Bank moderated by Susan Davis from Improve International.
World Toilet Day is a day to take action for global sanitation! It is a day to raise awareness about all the people who do not have access to a toilet – despite the human right to water and sanitation.Of the world’s seven billion people, 2.4 billion people still do not have improved sanitation. One billion people still defecate in the open. Poor sanitation increases the risk of disease and malnutrition, especially for women and children.
For World Toilet Day 2015, Emory students participated in “Cop-A-Squat” for World Toilet Day awareness and then traced squatting images to place all around campus to raise awareness about issues around the practice of open defecation and the need for improved global sanitation.
Innovation is the Key to Solving the Water and Sanitation Crisis in India
Dr. Bindeshwar Pathak, Founder, Sulabh International Social Service
Dr. Bindeshwar Pathak is the inventor of the two-pit compost flush technology that has helped provide low cost environmental toilets to millions of people in India. In 1970, he founded Sulabh International, one of India’s largest NGO working to promote human rights, environmental sanitation and waste management. The organization works in 25 Indian states, 1599 towns and has 50,000 volunteers. In 1974, he introduced the concept of building public toilets on “pay and use” basis, which are visible in most public places in India.
In 2014, he initiated a safe drinking water project in four districts in the West Bengal state in East India, where villagers are being provided clean drinking water at 50p per liter. A significant number of the villagers in these districts suffers from arsenic related diseases due to contamination of ground water. These treatment plants (installed with support from Sulabh) takes water from traditional ponds and rivers, which is arsenic free. The objective is to create a decentralized, people-friendly approach aimed at empowering communities by building capacity in them so that villagers, with training, can run the plant effectively.
Dr Pathak is a Padma Bhushan award recipient by the Indian government. He was inducted in the United Nations Environment Programme Global 500 Roll of Honour in 2003. He was awarded the Stockholm Water Prize in 2009 and received the Legend of Planet Award from the French Senate in 2013. His two-pit compost flush technology has been declared as a “Global Best Practice” by the United Nations HABITAT and United Nation’s Centre for Human Settlements.
