Finding all the Nuclear Waste barrels in GTA 5 is not the funnest part of the game, but if you are an achievement hunter or if you simply want to make some extra money, this is something that has to be done. We have a guide here with the Grand Theft Auto 5 Nuclear Waste locations: even though most of them are shown in your Trackify app, not all of them are.
In order to be able to start searching for the Nuclear Waste barrels, you will have to first complete the Merryweather Heist and get the submarine. Then, you have to go deep underwater and explore the coasts of Los Santos to find all the Nuclear Waste barrels. There are 30 barrels to be found and you get $32,000 for each found barrel, plus a hefty bonus of $250,000 if you find them all.
To make things a lot easier for you, we have a video below showing you the locations of the Nuclear Waste barrels:
