Pool Cleaning

Clean the Water Supply is a miscellaneous quest in Fallout 4.

Detailed walkthrough

 * 1) Talk to Sheng and ask him for work. He will ask you to clean out the water. The water is irradiated so you might need some Rad-x and Radaway.
 * 2) There are items in the water that you need to pick up. There are 5 of them and each one of them is marked.
 * 3) Once you are done, talk to Sheng again. He will pay you and he might also tell you that someone else cleaned the water before you and that they were blown up by a grenade while cleaning. You can see their skull in the water, and it is one of the things you need to take out of the water.
