Residents of the town of Denmark wait in line for cases of water on Thursday, Jan. 17, 2019. The city of Denmark has been embroiled in a water controversy of late after it was found that they had been using an non-EPA-approved disinfectant, HaloSan, in the water for the last 10 years until Clemson University ordered Denmark to stop using HaloSan this summer. The water had findings of lead and copper also.
