John H. Pujol

John H. Pujol - Chief Executive Officer

Johnny leads SimpleWater’s ArsenicRemover development team in the United States. He builds partnership among the private and public sector to understand and address the needs of small community water systems. 

Johnny has worked on drinking water projects internationally and domestically. As an analyst for Piramal Water in India, he designed a water quality monitoring system for a distributed network of water treatment ATM’s and also structured sustainable pricing schemes for drinking water access in urban slums. Under contract with the Inter-American Development Bank, Johnny collaborated with a research team in the Energy & Resources Group of UC Berkeley to model energy and carbon footprints of residential water usage in Mexico. Before co-founding SimpleWater, he worked on recycled water planning in California as an engineering consultant at Carollo Engineers.

Johnny graduated from the University of California Berkeley’s Graduate College of Engineering and Boston University’s Department of Economics.

Dr. Susan Amrose

Dr. Susan Amrose - Chief Science Officer

Dr. Susan Amrose oversees the technical development of the ArsenicRemover at SimpleWater. She has worked on scientific, social, and economic aspects of electrochemical (EC) water treatment since 2006. Dr. Amrose has been heavily involved with large scale field-trials and engaging industrial partners to commercialize. She teaches a graduate course at the University of California Berkeley on the commercialization and implementation of promising technology to resource-poor regions. As an inventor of  ECAR technology she has published research on both applied fundamental science relating to EC methods for arsenic removal. As a result of her water research, she received the Daniel Cubbiciotti Award from the Electrochemical Society

Dr. Amrose received her PhD in Physics from the University of California Berkeley in 2008. For her doctoral research she developed, lab-tested, and field-tested the EC system to remove arsenic. Susan previously worked in high-energy astrophysics at Los Alamos National Lab, CERN, and Silver Space Sciences Lab, and has experience with sophisticated electromagnetic systems and instrumentation.


Laura Chimelski

Laura Chimelski - Project Engineer

Laura Chimelski began working with SimpleWater while she was still a student at the University of California, Berkeley. She is responsible for all testing of US-based prototypes, conducting field analysis, and designs adaptations to meet the needs of California Small Drinking Water Systems.

Laura completed her B.S. in Civil Engineering at The University of Texas at Austin before earning an M.S. in Environmental Engineering at The University of California, Berkeley.


Siva Satyam - Project Engineer

Siva Bandaru is working on the implementation of Berkeley's ECAR large scale (10000 LPD) prototype in India. In addition to his work abroad, was part of the team that developed the original designs, fabrications, and testing plans for US-based ECAR pilot program.

Currently, Siva is a first year PhD student in Environmental Engineering at UC Berkeley. Siva received his Bachelor’s degree in Civil Engineering and his Master’s degree in Environmental Engineering from IIT Kharagpur, India in 2011


Nick Anchor - Design Engineer

Nick Anchor is responsible for the design of SimpleWater’s ArsenicRemover Treatment System and Special Projects. By utilizing his combination of structural engineering and environmental engineering process knowledge, he is able to work on robust arsenic-removing designs while ensuring structural longevity and durability of each prototype.

Nick's career with SimpleWater began after his graduation from the University of California, Berkeley with a Master of Science degree in environmental engineering. Nick graduated from the University of Illinois at Urbana-Champaign with a Bachelor of Science degree in civil engineering with an emphasis in structural engineering



Ashok Gadgil - Advisor

Dr. Gadgil provides oversight to technology innovation at SimpleWater. He is the inventor or ECAR technology and has vast award-winning experience inventing and commercializing technology for resource sustainability and health in disadvantaged communities.

Dr. Gadgil is the Director of the Energy and Environmental Technologies Division at LBNL and Professor of Civil and Environmental Engineering at UC Berkeley.  Dr. Gadgil holds a Ph.D. in Physics from UCB and an M.Sc. in Physics from IIT/Kanpur. Dr. Gadgil’s ECAR team recently won the Prince Sultan Bin Abdulaziz International Prize for Water (2013). He has won numerous other awards and honors for his inventions, including the Heinz Award (2009), as well as the Zayed Future Energy Prize, and the Lemelson-MIT Global Innovation Award (both 2012). Dr. Gadgil has substantial experience in technical, economic, and policy research on energy efficiency and its implementation - particularly in developing countries. He has pioneered the way to accelerate access to compact fluorescent lamps for poor households in developing countries. He has also invented, developed, and licensed (through LBNL) an effective, low cost water treatment technology for bacterial contamination – UV Waterworks™ - that is now the cornerstone for a rapidly growing California start up providing clean water to over 5 million people in India daily. Dr. Gadgil also designed the Berkeley Darfur Stove along with an innovative supply chain suitable for war-torn and resource poor Sudan, which has successfully delivered fuel efficient stoves to over 26,000 refugees in Darfur.

During 1993-96, Dr. Ashok Gadgil invented and perfected UV Waterworks™, a low cost, low maintenance, rugged device that disinfects drinking water using UV light.  It uses only 60 Watts of electricity, disinfects 4 gallons of water per minute, and the cost of disinfection is less than a nickel per metric ton of water.  UV Waterworks™ has won substantial recognition and numerous awards. This invention is vital because more than 200 children (below age 5) die each hour from waterborne diseases in the developing world, and his invention will literally save tens of thousands of children’s lives each year. A U.S. private company, WaterHealth International (WHI), has been licensed by LBNL to manufacture and market Prof Gadgil’s device.  WHI sells clean water to more than 4 million customers daily at a cost of about 2 per 10 L (3 US gallons) and is financially sustainable; covering costs of operation, maintenance, repairs, and salaries.


Steve McDonald - Advisor

Steve directs the IRM Practice which includes: Energy Management; Business Solutions; Water Reuse/Resources; Watershed Management; Integrated Modeling; Advanced Planning; and Sustainability Services. He is an expert in sustainable integrated water system practices, including low impact development (LID) and green infrastructure (GI). He is recognized in the industry for his innovative contributions to the practice of integrated planning approaches, tools, and techniques for sustainable and integrated water, wastewater, and stormwater systems. Steve has directed major strategic master-planning efforts some of the largest cities and municipalities in the West. This includes over $15 billion in wastewater facilities in the last 15 years, involving more than half the population in Northern California.


Environmental Justice Coalition for Water

The Environmental Justice Coalition for Water is a statewide coalition of grassroots groups and intermediary organizations building a collective, community-based movement for democratic water allocation, management, and policy development in California.  EJCW empowers low-income communities and people of color throughout California to advocate for clean, safe, and affordable water for their communities. 

We envision all communities throughout California having access to safe and affordable water, clean rivers, streams, and bays for personal, cultural, ceremonial, and recreational uses. 

EJCW plays a critical bridge-building role in connecting grassroots communities and statewide policy advocates across California. We maintain a strong presence in Sacramento, and have conducted many successful advocacy campaigns. We are coordinating a statewide message on the importance of identifying and meeting the water needs of the most under-served communities in California. By connecting our members to each other and potential allies throughout the state, as well as tackling structural inequity in how California’s water resources are managed, we are building a broad movement for water justice.
