An important part of the sulfur project is an investigation of the speciation of the reduced sulfur species in drinking water sources.
The above research is being carried out using a variety of techniques that include Atomic Absorption Spectroscopy (AAS), High Performance Liquid Chromatography (HPLC), and Voltametric techniques.
