What Is This Neon Green Slime Flowing Into a Texas Creek?

Unfortunately for peace of mind of local residents, the neon green substance flowing into a Dallas creek was not in early celebration of St. Paddy's Day. According to reports, the florescent green goo was spotted on Wednesday and was later traced back to a local hospital after hazmat crews were called onto the scene.

Gizmodo has some speculation as to the source:

Was it a biological attack? Alien bodily fluids? Mutant blood?

Thankfully, it was none of the above. In fact, it was just plain, completely non-toxic green dye. WFAA reports that the Medical City Dallas Hospital was using the dye in a cooling tower to check for plumbing leaks. According to WFAA, a hospital spokesperson said those working on the leak evaluation didn't realize the dye would eventually make it to White Rock Creek.

Watch the report:

WFAA reports that those first on the scene dammed the ditch until the substance was identified as non-hazardous. At that point, the green dye was allowed to flow into the waterway.

According to the report, the dye is 99 percent water.
