This is a graph comparing the tritium (HTO) concentration in the Hudson River at the Indian Point intake and discharge points. Although tritium is ubiquitous in the environment, periodic increases in tritium concentration at this point are likely due to allowable water discharges from the facility. All discharges are well below regulatory limits. A column has been added for values which can be graphed. Readings where a less than value is displayed show a value that is less than the detection limit of the measurement method and are essentially equivalent to 0. Variations in detection limit are due to variations in sample collection and measurement instrument performance. For more information please visit http://www.nyhealth.gov/radiation or the "About" tab.
