The City of Wichita says a chemical used in the water treatment process leaked into the Arkansas River early Wednesday morning. It happened near downtown.

City officials say the chemical, known as ferric sulfate, leaked through a corroded drain pipe at the treatment plant. Ferric sulfate is used to settle out particles in untreated water as it flows into the plant.

The Kansas Department of Health & Environment was contacted and said the leak does not pose a threat to the public.

The Kansas Department of Wildlife, Parks & Tourism was also contacted due to a fish kill that resulted due to the leak.

The City says the leak has been plugged.
