Abstract
Hyperspectral analysis of water samples taken from public water resources in the New York City metro area has demonstrated the potential application of this type of analysis for water monitoring, treatment and evaluation prior to filtration. Hyperspectral monitoring of contaminants with respect to types and relative concentrations requires tracking statistical profiles of water contaminants in terms of spatial-temporal distributions of electromagnetic absorption spectra ranging from the ultraviolet to infrared, which are associated with specific water resources. To achieve this, it is necessary to establish correlation between hyperspectral signatures and types of contaminants to be found within specific water resources. Correlation between absorption spectra and changes in chemical and physical characteristics of contaminants requires sufficient sensitivity. The present study examines the sensitivity of modulated resonance features with respect to characteristics of water contaminants for hyperspectral analysis of water samples.
