Indio Water Authority, California Chromium removal from drinking water

From 2010 – 2013, extensive groundwater testing around the Coachella Valley had confirmed the widespread presence of naturally occurring chrome-6 in the surrounding aquifers.
In response to this public health concern, the CA Department of Public Health issued a Maximum Contaminant Level (MCL) of 10ppb, requiring all public municipalities to implement appropriate chrome-6 drinking water treatment systems by 2020.
In response to this public health concern, ToxSorb engaged the Indio Water Authority (IWA) to commission a drinking water pilot, showcasing its proprietary MAC media for selective chromium adsorption and reduction to
non-toxic elements. The pilot operated in two phases, beginning in late-2014 and completing in early-2016, the first demonstrating the scalability of the system and the second focused on optimizing the process of adsorption,
regeneration and brine recycling.
