Water contaminants can be quantified using a light based sensor called the s::can, a commercial sensor which scans light wavelengths within the visible light region. Contaminants, such as bacteria or organic compounds, change the fingerprint of light absorbance and this change is used to both identify contaminants and to determine their amount. This sensor operates continually and makes measurements every few seconds. http://wsp.arizona.edu/
