because the early nineteen seventies tens of millions of shallow tube wells had been put in in Bangladesh and India, resulting in a limiteless but silent disaster: these wells draw from arsenic-contaminated aquifers. Latest research report that up to 20% of all grownup deaths in Bangladesh at the moment are arsenic-comparable. Berkeley researchers have advanced a generation, ElectroChemical Arsenic Remediation (ECAR), that robustly, reliably, and cheaply produces arsenic-safe water within a sustainable and scalable trade type. ECAR makes use of an innovative means: a small electrical charge creates rust debris from unusual steel plates which bind to arsenic, bearing in mind effective filtration. The generation is designed to be robust and coffee-maintenance enough to work in deep rural spaces with virtually no tech backup or reinforce.
