Unknown Cause Behind Bright Green Water in Springfield Area Creek
*A joint investigation is underway after discoloration in Helmer Creek, Calhoun County.*
CALHOUN COUNTY, Mich. — A bright green mystery has emerged in Calhoun County, sparking a coordinated investigation between local officials and the state as authorities search for the source of unusual water discoloration in Helmer Creek.
The City of Springfield, the Calhoun County Sheriff's Office, and the Michigan Department of Environment, Great Lakes, and Energy (EGLE) are working together to determine what caused the water to turn an unnatural green color.
"The cause remains unknown at this time," said Calhoun County Sheriff's Office officials. "The discoloration has largely dissipated since the incident came to light Tuesday, March 31, but investigators continue searching for the source."
The incident first came to light on Tuesday, March 31, when a social media post brought the unusual sight to the attention of authorities. Since then, the green discoloration has "significantly dissipated" according to Springfield officials, but the investigation continues to identify where it originated.
Drones and Water Samples in the Hunt for Answers
Sheriff's office emergency management personnel have established an active scene at the creek, deploying drone technology to trace the path of the discoloration and pinpoint potential origin points.
"The scene is very active, with drones in the area as they investigate and try to trace the full path of the discoloration to identify and potential origin points," reported Springfield Director of Public Works Chaz Wilkey.
EGLE officials must still collect water samples to determine exactly what chemical or substance caused the water to turn green. Wilkey noted there was no odor associated with the water.
Residents Warned to Avoid Affected Area
Officials have issued a warning to residents in the Springfield area, advising them to avoid contact with Helmer Creek until investigators gather more information.
"You're asked to avoid Helmer Creek starting at Helmer Road at Bishop to the Kalamazoo River for the time being," Springfield officials stated.
The affected area includes the creek from Helmer Road at Bishop all the way to where it meets the Kalamazoo River. Springfield crews are investigating behind Thunderbird Village, where officials surmise someone may have dumped green dye into a nearby storm sewer.
Community Asked to Share Information
The Calhoun County Sheriff's Office has asked anyone with information about the incident to come forward. Officials can be reached at 269-781-0880, or residents can submit anonymous tips through Silent Observer at 269-964-3888.
"Anyone with information about the incident can contact the Calhoun County Sheriff's Office," authorities said. "We will provide updates as the investigation continues."
Broader Context of Water Quality Concerns
The investigation comes at a time when water quality issues have drawn increased attention across Michigan. Recently, prosecutors alleged that Douglas Environmental and its president falsified water testing results at private water systems serving mobile home parks and condos throughout the state.
What Happens Next
As of now, the investigation remains ongoing. EGLE continues to monitor the area and collect samples, while the Calhoun County Sheriff's Office maintains an active presence at the scene with drone surveillance.
Springfield officials have shared photos of the green water with the community, warning residents to stay away from the creek until further notice. The full extent of the affected area and the ultimate cause of the discoloration remain to be determined.
