SimpleWater Tap Score

Who We Are

SimpleWater is a water science and technology company founded at the University of California in Berkeley with the mission of providing safe water to everybody. We are a team of engineers and designers with a vision to improve the way we test, treat, and monitor water pollution.

We want your tap water to taste great and be safe so we provide professional water quality testing and treatment services through our core product Tap Score, a quick and easy laboratory testing kit for home water quality testing.

SimpleWater is also engaged with research into electrochemical arsenic remediation. Read more here about the cutting edge water treatment technology which SimpleWater is developing for the most dangerous and complex water contaminants.



John H. Pujol - Chief Executive Officer

John leads SimpleWater’s ArsenicVolt and Tap Score development teams in the United States. His background includes work as a water quality engineer for clients in the USA, India and Mexico. John graduated from the University of California Berkeley’s Graduate College of Engineering and Boston University’s Department of Economics.

Julio Rodriguez - Chief Technology Officer

Julio is responsible for Tap Score software engineering and data analysis efforts. He has a background in software product development and information technology, with a 14 year history of successful enterprise and startup projects. Julio is a graduate of the University of Michigan in Ann Arbor.

Dr. Susan Amrose - Chief Science Officer

Dr. Susan Amrose oversees the technical development of the ArsenicVolt 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 ArsenicVolt. 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.

Dr. Ashok Gadgil - Advisor

Co-Inventor of ECAR, Lawrence Berkeley Lab Division Director, Professor, National Inventors Hall of Fame. more

Henry McCann - Water System Specialist

Henry conducts public policy research on community drinking water systems at the UCLA Luskin Center for Innovation. His research focuses on identifying solutions for the technical, managerial, and financial challenges of providing safe drinking water in rural and small drinking water systems. He was the lead author of the Los Angeles County Community Water System Atlas and Policy Guide (2015), a system-level characterization of threats to water supply reliability and vulnerable populations served by community drinking water systems in Los Angeles County. State water quality regulators are using this report to identify needs for technical assistance and financial support for small drinking water systems in California. He brings to SimpleWater an expert understanding of drinking water supply networks, water system operations, and safe drinking water regulations.
