ArsenicGrip utilizes Electrochemical Arsenic Remediation (ECAR) technology invented in the Gadgil Lab of Lawrence Berkeley National Laboratory and the University of California.

ECAR was originally developed as a radically reliable solution to what the World Health Organization has called “the largest mass poisoning in history.” As many as 77 million people in Bangladesh – a nation with 20% of its people living below the $2 poverty line – are chronically exposed to dangerous levels of arsenic in their drinking water; moreover, the US National Institute of Health attributes 1 in 5 adult deaths in the region to arsenic poisoning.

In this critical setting, inventors at the University of California and the Lawrence Berkeley National Laboratory harnessed the power of fundamental science and systems-based thinking. Five years of dedicated social research, technical R&D, and economic analysis built a process of arsenic removal that was very affordable, relied on a minimalist supply chain, and required minimal operational oversight. These dramatic conditions not only produced one of the most promising solutions for Southeast Asia but also a novel technology very much in need in the rest of the world.

Utilizing the same ECAR principles, ArseniX can provide unprecedented reliability, simplicity, and affordability to American communities. More than 56 million Americans drink water with potentially harmful arsenic contamination. Many families do not know whether their wells contain the poison. Beginning in 2014, SimpleWater began testing ArseniX for commercialization in the USA.



ArseniX uses electric current to destabilize suspended, emulsified, or dissolved contaminants. The current dissolves a sacrificial mild steel plate in contaminated water. The dissolved metal hydrolyzes and precipitates, generating an active adsorbent floc that helps coagulate or adsorb contaminants. Large contaminant-laden flocs are then separated from water via filtration or settling processes.

In some cases beneficial oxidation of the contaminant also occurs, aiding removal. In fact, the oxidation of As[III] - [V] is a particularly important strength of the technology. Existing remediation systems require advanced chemical treatment prior to RO to remove As[III], ECAR inherently oxidizes As[III] to As[V] for easy coagulation.

ArseniX Treatment Units have a small footprint and are easily installed within your existing water treatment and distribution system. No hazardous chemicals, No messy media, No complex membranes.

1 | Naturally occuring from arsenic poison dissolves from rock and soil into underground aquifers. Arsenic concentration is readily exacerbated by increased demand and changes to water availability.
2 | Automated and solar-powered low voltage electric current dissolves iron from the ArseniX electrodes. The resulting iron flocs actively adsorb arsenic from the water.
3 | Contaminant-laden flocs are separated from water in a simple filtration process, generating non-toxic waste.
4 | Clean Water is distributed to homes, meeting the EPA's health standard without changing the taste or removing the natural mineral content of the local groundwater.
