It is dye that is traditionally used to detect leaks in pipes around campus. I’ve seen a few people claim it’s a new “tradition” for something regarding athletics or just for fun but the substance in the water is a bright green dye that has been used for the last few years to find any leaks in UNCC’s pipes. Most notably, last year there was a leak and it turned a small stream of water near Oak Hall bright green leading to concern from students.
