How to Start The Mystery Polluter Quest
To begin the Mystery Polluter side quest in The Legend of Zelda: Breath of the Wild, speak with Dalia in the alley to the right of The Noble Canteen from 6:30 am to just before nightfall.
She’ll be crying because she wanted to plant an orchard and clean up the area, but trash keeps getting washed down the waterway.
How to Complete The Mystery Polluter Side Quest
Discover the Source of the Trash
To track the source of the treasure, climb up the wall next to where the water is flowing and follow along the aqueduct.
After a little while, you’ll start to see trash coming from upstream.
Head in the direction that the garbage is coming from to spot a Gerudo eating watermelons and dropping the leftovers in the water. Speak with her (Calyban) to tell her about the girl. She’ll only agree to move if Link does her a favor.
Obtain 10 Wildberries
For Calyban to move, you’ll need to bring her a wildberry to try. She’ll mention that they grow in the snowy areas of the Gerdo Highlands and are pretty rare. At this point, though, she changes the required number from one to ten.
You can find a few around Risoka Snowfield and the surrounding areas, in the mountains north of Gerudo Town
Bring Calyban the Wildberries
Once you have the ten wildberries, return to Calyban and speak with her to deliver them. After eating them all, she feels bad about the little girls and heads off to help her clean up.
Report back ot Dalia
Return to Dalia and speak with her. She’ll thank you for your help and share a hydromelon with Link as a reward. She’ll also mention that the lady shared some wildberries with her, so now she’s turning the orchard into a wildberry patch!
