Our volunteers 



Fernanda Arce

Fernanda Arce is a civil engineer from the state of Durango in México. She’s part of our Research and Technology Development team. Fernanda is working with our team to strengthen and improve the production process of ceramic water filters and everything that their manufacturing involves (design, mixture, mold, adapter, etc.).  Fernanda graduated with a Bachelor of civil engineering from the Instituto Tecnológico de Durango. While she was studying at the university she moved to Yucatan and started to collaborate with Dr. Pedro Castro at the Lab of Chemistry and Concrete at CINVESTAV Merida where she had the opportunity to work with ceramic materials for construction field. When Fernanda has time, she likes to write, watching good movies, and meet new people. 


Sarah Hartman

Sarah Hartman is an environmental engineer from the United States who focuses on water quality and water resources. She started volunteering for Caminos de Agua shortly after receiving her Bachelors of Environmental Engineering from the University of Delaware. Sarah works with the Research and Technology Development team, where she is assessing different filter material for removal of arsenic and fluoride from groundwater. Before joining Caminos de Agua, Sarah worked on various US-based and international projects including a drinking water treatment system in the Philippines, a wastewater system in Mongolia, membrane toilets in India, and a floating wetland treatment system in the United States. She is passionate about providing affordable, safe water to all. Outside of work, Sarah enjoys learning new languages, spending time in nature, and salsa dancing.



Melissa Landman

Melissa Landman is a recent mechanical engineering graduate from the United States.  She is volunteering on the growing Research and Technology Development team, working on a variety of mechanical design projects to improve and redesign existing systems.  She is currently working on improving the existing rainwater harvesting cistern design by prototyping a water depth sensor.  After the prototyping phase is complete, she will take the design out into the field to monitor community response.  

Melissa graduated with a Bachelor of Mechanical Engineering and a minor in Civil Engineering from the University of Delaware.  During university, she was involved in an international development non-profit called Engineers Without Borders as a Project Manager for a water and sanitation project in the Philippines.  Recently, she worked in Guaynabo, Puerto Rico on a constructed wetlands project for La Marquesa Forest Park.  Through these two projects, she developed a passion for international development work, specifically in the realm of potable water and sanitation.  This growing passion led her to Caminos de Agua, where she can use her mechanical and international development background in a very hands-on manner.  In her free time, Melissa enjoys playing soccer and tennis, as well as cooking.

Simona Dossi

Simona Dossi is an Engineers Without Borders UK volunteer, who works on Caminos de Agua’s Research and Technology Development team. Simona is from Milan, Italy and has been studying Chemical Engineering in Edinburgh, Scotland. This volunteer placement is serving as Simona’s thesis project of her MEng Chemical Engineering degree at the University of Edinburgh. The project’s aim is to contribute to Caminos de Agua’s investigation of adsorption filter materials and filter design to eventually deploy a low-cost prototype filter that successfully removes fluoride and arsenic from the contaminated groundwater in San miguel’s municipality. Before joining Camino’d de Agua Simona worked on laboratory research of a Reverse Osmosis system in Edinburgh. Outside of work, she enjoys live music and hiking.
