While it may be complex, the prevention and treatment of contaminated water is possible. Founded in 2010, 33 Buckets is a registered 501(c)(3) nonprofit organization based out of Tempe, Arizona who partners with vulnerable communities and local partners to provide sustainable access to clean drinking water and WASH (Water and Sanitation for Health) training. Prior to 2018, 33 Buckets had completed drinking water projects in Bangladesh, the Dominican Republic, and Peru. In the summer of 2018, the 33 Buckets team returned to the Cusco region of Peru in an effort to assess more communities in need of clean drinking water infrastructure. In Cusco, 33 Buckets works closely with the Peruvian university, Universidad San Ignacio de Loyola (USIL). The primary purpose of this partnership is to identify communities in the Cusco region with contaminated water sources and a strong interest in improvement of current systems. Throughout this assessment trip, two communities were initially identified as potential partners, Occopata and Mayrasco. The results of bacteria tests showed a presence of Escherichia coli, commonly known as E. coli. When consumed, especially repeatedly, select strains of E. coli will cause severe diarrheal illness. Interviews with community members confirmed that common symptoms of water related disease are prevalent, especially in children. In Occopata and Mayrasco, there is an absence of support for water services from the municipality. Consequently, there is a volunteer-based water advisory board known as Junto Administración de Agua Sanitemeniento (JAAS). JAAS, in most nearby communities, currently utilizes a drip chlorination system in an attempt to disinfect bacterial pathogens from their water source. However, chlorine disinfection requires a precise dosing in order to be effective. In excessive amounts, chlorine will taste and smell of chemicals, likely producing negative feedback from community members. As a result, chlorine levels often are below the necessary level for disinfection. Chlorine tests performed by the 33 Buckets team confirmed that chlorine levels were insufficient to disinfect E. coli.
During the assessment trip, the 33 Buckets team provided a temporary solution to make chlorine disinfection more effective. Following the 2018 assessment trip, 33 Buckets formed a team of student engineers with the primary goal of furthering the technological development of a chlorine disinfection system to be implemented in communities with bacterial infected water sources. This student team was formed through the EPICS (Engineering Projects in Community Service) program at Arizona State University. The purpose of the program is providing a platform for undergraduate engineers to design solutions that create positive impact the greater community. From August of 2018 through April of 2019, the team developed the design for a continuous chlorine disinfection system that automatically tests for residual chlorine levels at multiple points throughout a community. The system is powered entirely from a low-cost solar panel, requiring a minimal amount of sunlight for full functionality. Moving forward, the goal of project development is to create an autonomous feedback loop that will adjust the amount of chlorine exposure to incoming water flows based on the results of the automatic residual chlorine test. The team also hopes to implement automatic data collection for remote monitoring of water quality in addition to onsite test results. The vision of the proposed solution is a network of chlorine disinfection systems around the Cusco region that ultimately will provide access to clean drinking water, indefinitely. This model of user-friendly purification, automatic testing, and data collection can be adjusted and applied to any region around the world experiencing health issues from consumption of contaminated water. A low-cost, scalable, and reliable water disinfection system has the potential to make significant increases in the quality of life for millions of people.
biochar. This research has found biochar to hold massive potential as a means of stabilizing current levels of atmospheric carbon. Furthermore, the research and resources to massively expand biochar production exist, yet one could easily argue the industry is not expanding quickly enough given its known potential benefits. This paper serves to address this lack of growth, and identified a lack of formalized networks for knowledge and innovation exchanges amongst biochar production firms as a leading obstacle to quick expansion. I focus on two particular biochar production firms operating in vastly different contexts and analyze both through a conceptual framework known as “knowledge networks”. In depth literature on the topic of knowledge networks highlight the dynamics of exchange, including the obstacles in establishing such a network. I applied the findings from a multitude of case studies centered around knowledge networks to biochar production, asserting that exchange networks centered around reciprocity would serve as a catalyst to the growth of the biochar industry. I also assert that public research institutions such as Arizona State University would play a critical role in such a network, as they would serve as a mutual party connecting two private entities. Private biochar production firms around the world would be exposed to new knowledge and information that would serve to maximize the energy value of their product while reducing the environmental externalities associated with their process.
Water scarcity has become an especially urgent problem in Maasailand. Maasailand is one of the major worldwide destinations for wildlife game drives in Africa. In this project, a recyclable car wash system is considered for design in Maasailand, Kenya. Background research was conducted to see the feasibility of the design. Water filtration methods such as coagulation were researched, analyzed and tested to ensure all the customer needs were met. The washing and collection aspects of the car wash were also further explored and designed. This joint project which is part of capstone is to also be implemented into the bigger project known as the Maasai Autotmotive Education Center and in support of the Mara Guide Association (MGA), an organization run by the Masaai people in Kenya.
Food insecurity and hunger are strongly interconnected with poverty and are major concerns across the world. Poverty stems from many interconnected issues and creates what are known as Food Deserts. The challenge then becomes: How do we mitigate the effects of food deserts to achieve food security? This paper proposes a design and a potential solution to address this question of food insecurity with the modification of a traditional aquaponics system that can potentially deliver the same product at a lower cost. Stakeholder input was key to the product design and was captured through a set of carefully conducted interviews. An in-depth literature review also informed the redesign process, and a final, viable product was proposed. Thus far, the proposed aquaponics system has demonstrated to be a promising cost-effective, sustainable, solution that could provide a majority of the food needs for a family.
During a joint ASU-Prescott College visit to the Maasai Mara in Kenya in June-July 2018, it became obvious that many Maasai women produce beadwork sold locally to help support their families. The difficulties they face include inconsistent sales due to lack of customers, lulls in tourism, and unfair competition. During this visit, the idea of selling the crafts online via Etsy was suggested. It received overwhelming support from the community through MERC, the The Maasai Education, Research and Conservation Institute.
