Water World reopened Friday after being closed for a day due to potential water supply contamination.
The park was shut down Thursday after the Tri-County Health Department said untreated water might have affected drinking fountains and been used to make ice, drinks and food at concession stands on Monday, Tuesday and Wednesday.
Health department staff visited the park Friday morning and gave them clearance to reopen.
“Water World worked closely with Tri-County Health Department to sanitize, test and confirm that the water in drinking fountains, ice machines, concession stands, and swimming pools is safe,” the park said in a statement.
Anyone who ingested water at Water World on Monday, Tuesday, or Wednesday could still get sick up to 45 days after exposure. Symptoms include vomiting, diarrhea, and fever. Anyone who visited Water World on those days and experiences these symptoms should call the Colorado Department of Public Health and Environment at 303-692-2700, and then call their doctor.
