Grand Theft Auto V (GTA V) - All Nuclear Waste Collectible Locations

There are a total of 30 Nuclear Waste Collectibles in GTA V.
Finding all of them will earn you the “Waste Management” trophy or achievement.
To collect them you need to buy the Sonar Collections Dock with any character. This property can be bought after completing the “The Merryweather Heist” story mission. The dock costs $250,000. You need to pick up the waste with the submarine. The submarine always spawns at the dock.
Pretty much all of the nuclear waste is at the bottom of the ocean. Buying the docks will also give you a new app called “Trackify”. The app starts automatically when entering the submarine and provides a radar that points to the next collectible. The order in this video matches with the order of the Trackify app.
However, the app won’t mark any of the waste on your in-game world map. Sometimes a piece of waste is miles away on a different part of the coast. The submarine is also very slow. If you collect everything in one run it will take about 2 hours.

On the bright side, getting all this stuff will help you uncover the ocean map further and you will get a lot of money. $23,000 per piece of nuclear waste you find and a $250,000 bonus after finding the last one.
