Description

Small and inexpensive point-of-use treatment systems for simultaneous removal of arsenic and nitrate from groundwater Small and inexpensive point-of-use treatment systems for simultaneous removal of arsenic and nitrate from groundwater This project directly meets two of the goals indentified in Arizona/Sonora Border 2012 Priorities List for 2009: (1) Goal 1 - Reduce Water Contamination/Sub goal 4 - Pilot small, potable water systems; and (2) Goal 4 - Improve Environmental Health/Sub goal 4 - Reduce exposure to arsenic. Arsenate is a prevalent form of arsenic found in the groundwaters of southwestern US in concentrations greater than the US EPA promulgated maximum contaminant level (MCL) of 10 g/L. Nitrate is also present in these groundwaters in concentrations that could cause serious health problems. The goal of this project is to demonstrate that small and inexpensive point-of-use treatment systems can be developed and used to simultaneously treat arsenic and nitrate from groundwater in small and poor US/Mexico border region communities. This project encompasses three task oriented objectives focused on demonstrating that a simple and inexpensive small system for simultaneous removal of these contaminants below the established MCLs could be implemented in small rural communities located in the US/Mexico border region. The project includes in-kind contributions by the ASU team and the Tohono Oodham Nation (TON). It also encompasses an educational component as part of a developing collaboration effort. A successful outcome of this project could improve the quality of life in many small and poor communities in regions of Mexico and the US characterized with high arsenic and nitrate occurrences and would create a platform for development of inexpensive drinking water treatment solutions based on the decentralized water treatment approach.
