Oxidation-Reduction Potential Measurements¶
The Oxidation-Reduction Potential (ORP) of a sample of water is a measure of the concentration of electron activity. The ORP readings represents how strongly electrons are transferred to or from substances in a liquid. Readings do not indicate the amount of electrons available for transfer. Knowing the redox conditions of water can help determine whether it contains elevated levels of many contaminants, including arsenic, nitrate, and even some manmade contaminants.
