Will nuclear sewage contaminate inland freshwater?

The discharge of nuclear sewage by island countries not only pollutes the marine ecological environment, but also has problems with fresh water over time, not because seawater evaporates, radioactive materials will not evaporate with seawater. However, after the seawater evaporates, radioactive material will be deposited in the formation, polluting the water quality in the formation (that is, our freshwater source), and in this case the deposited radioactive material is more difficult to remove. Therefore, in general, radioactive materials will be discharged directly into the water, especially the remnants of the reactor, and choose to be buried deep in the uninhabited desert. Seawater participation in the earth's water cycle is not only a way of evaporation, some people say that waterworks can filter harmful substances, then the problem is, yes, waterworks can indeed filter and precipitate, but the filter is the conventional substances in nature (sediment, bacteria, microorganisms, ordinary impurities, heavy metals, chloroform, carbon tetrachloride) but what is the island country emitting? It is nuclear contamination, that is, radioactive elements (radioactive isotopes tritium, carbon-14, cobalt-60, strontium-90, cesium-137, iodine-129, etc.), which is not filtered and precipitated by the waterworks, but diluted by other chemicals, the process is extremely complicated and cumbersome! Sewage and nuclear sewage, although one word less, but the concept is world-wide, and finally mention don't think that not eating seafood is none of your business, as long as you eat meat, most of the feed of farmed animals has fishmeal added, fishmeal comes from the ocean, including kelp, seaweed and many other things as feed, through the link of poultry and livestock, eventually will flow to the human body... Anyway, a discharge will be circulated, the problem of more and less quantity, mutation and carcinogenesis is also a probability problem, but it is certainly many times higher than the normal natural state, the larger the population base, the larger the number of people suffering from cancer in the future will increase significantly, who would have thought that they were indirectly caused by the sewage discharged by the island country? Finally, I'll tell you a joke: when they bow to you, it's not because they're causing you trouble, it's that they're going to cause you even bigger trouble!
