EXSKF: 5,000 cubic meters, or 5,000 tonnes of this water is in the trench.

Note: 5,000 cubic meters of water is equal to 5 million liters. One liter was found to contain 2.35 billion becquerels of cesium. If this concentration is consistent, the total amount would be nearly 12 quadrillion becquerels of cesium in this one trench.
