Field-ready and rapid trace-level detection and speciation of arsenic in water

DESCRIPTION (provided by applicant): Arsenic in drinking water is a proven cause of cancer, and continues to pose a significant human and environmental threat in the U.S and globally. Arsenic has been found in drinking water in forty-nine States and constitutes a major pollutant in many Superfund sites. This omnipresence requires adequate monitoring equipment that is not only fast, but also combines the sensitivity and performance of laboratory-grade equipment with the ease-of-use and mobility of test kits.OndaVia has developed an analytical platform using Surface-Enhanced Raman Spectroscopy (SERS) for trace chemical detection in water. This platform successfully demonstrated reliable detection of trace- levels of perchlorate at a California decontaminationsite. OndaVia proposes to adapt its inexpensive, field-deployable and robust solution for ultra-sensitive and rapid arsenic monitoring. This novel innovation, capable of speciation and quantitative arsenic measurement at ppb (parts per billion) level
