Red water on Riverwalk explained
Visitors to the Jasper Riverwalk were surprised to see red water flowing under a bridge along the popular walkway Monday afternoon.
According to Chad Mundy, the city’s stormwater coordinator, he and the Indiana Department of Environmental Management were notified of the oddly colored water and tracked it back to a local manufacturer.
He suspected it was a dye being used by the company to test drains. Sometimes, too much is used and can cause discoloration to occur over large areas.
IDEM has taken over the investigation at this point.
He explained that it was an isolated incident and since it was no longer being released, the issue would dissipate on its own.

Does this mean the company’s drain pipes leak into the river?
Storm drains do.
Know what you mean…am curious also. Hopefully the IDEM folks will determine which system/pipes it was, and if any violation(s) and/or corrections needed.
When I worked at Kimball, we were instructed to dump antifreeze coolant, used for metal drilling, directly into the city drainage. I would not be surprised if these practices are continuing within many of the local manufacturing facilities.
