“A Toxic Trail” is a quest that was added to ARC Raiders with the Cold Snap update.
Shani needs your help to investigate someone who’s been poisoning the water supply. Now that the water is clean again, it’s important to find the culprit before anyone gets sick from the toxic waste. It’s time to figure out who’s responsible.
In this quick guide, we’ll help you complete this quest as easily as possible.
A Toxic Trail | Quest Guide

To complete this task, head to the north side of the Water Treatment Control building in the Dam Battlegrounds map.
You’ll need to locate the Flood Spill Intake – it’s a wastewater drain with a barrel next to it. Just getting close to the barrel will finish the first part of this quest. It’s not pleasant, but it needs to be done!

After you’ve finished that, head west into the swamp. You’ll see an old, abandoned truck with some barrels nearby.
When you get close to the truck, you’ll be asked to do two things. First, take a picture of the barrels in the truck bed. After you’ve done that, click on one of the front wheels.
Once you’ve investigated the truck, you’ll have completed all the necessary steps. Now, simply share what you’ve discovered with Shani to finish the quest.
That concludes the “A Toxic Trail” quest – it’s a pretty straightforward one! If you’re looking for help with other quests from the Cold Snap update, we’ve got a complete guide available.
