Arc Raiders: Source of the Contamination Quest Walkthrough

Once you’ve assisted Celeste in identifying the foul waters during the Water Troubles quest in Arc Raiders, the mystery of the wasteland’s ecology takes a darker turn. Celeste isn’t one to let a problem sit; she’ll promptly task you with tracking down the literal “Source of the Contamination.” This mission sends you deep into a high-stakes hotspot within the Dam Battlegrounds.

At Digital Tech Explorer, we’ve spent significant time navigating the hazardous surfaces of the Buried City. While this quest might look straightforward from the mission thumbnail, the specific interaction point is tucked away in a dangerous corner. Here is TechTalesLeo’s guide to surviving the trek and clearing the objective efficiently.

How to Complete Source of the Contamination in Arc Raiders

Your journey begins at the Water Treatment Building, located centrally within the Dam Battlegrounds. You are searching for the flood spill intake. You can find this on the northern perimeter of the facility, right where the concrete structures meet the edge of the Swamp. It’s a low-lying area filled with murky, stagnant water surrounded by concrete ramps.

Pro Tip: Memorize this location. You’ll be returning here later for the A Toxic Trail quest, so getting familiar with the layout now will save you a headache in future runs.

Once you arrive at the intake, look for a bright yellow barrel partially submerged in the water. It’s leaking a steady stream of pollutants. Approach and interact with the barrel to complete the primary objective.

Since this area is often crawling with hostile machines, your best bet for a clean getaway is the Central Swamp Lift, situated just a short sprint to the north. However, stay sharp—our field testing shows that a Rocketeer frequently patrols this extraction point. While you’re in the vicinity, keep your eyes peeled for mushrooms for Scrappy; you’ll eventually need 12 for his final upgrade, and they are notoriously elusive.

Quest Rewards

While the rewards for Celeste’s task might not be legendary loot, they provide essential components for any Raider looking to maintain their gear. Here is the breakdown of what you’ll receive upon completion:

Reward Item Quantity Utility
Steel Springs 5 Essential for mechanical crafting and repairs.
Duct Tape 5 The backbone of wasteland DIY crafting.
Mod Component 1 Used for enhancing weapon and gear performance.

It’s a modest haul, but in the world of PC gaming extraction shooters, every scrap of Duct Tape counts toward your survival. For more in-depth analyses and mission walkthroughs, keep it locked to Digital Tech Explorer.
