The Southern Iowa Rural Water Association posted on its website Saturday that the advisory had been lifted for all of their customers.
The drinking water warning was placed June 1 after the 12-Mile Treatment Plant at Creston Water Works had a failure in its filtering system.
Nine Iowa counties were affected by the advisory and starting the night of June 10, cities started getting access to drinkable water again.
Ringgold County’s rural areas were the last to have the advisory lifted.
For the past 16 days, people under the advisory had to use boiled or bottled water for drinking, making ice, washing dishes, brushing teeth and preparing food.
Hy-Vee donated 20,000 gallons of water to people in the affected areas.
Residents were also concerned over the growing cost of the outage.
Dan McIntosh, general manager of the SIRWA and Creston Water Works’ treatment plant, said the board would have to discuss billing and costs for impacted customers but added that water was "still available."
In an update released by the association, Kevin Glick, owner of Service Techs on the west edge of Creston, was recognized for volunteering his time and fuel to the cause, flying samples to Storm Lake on at least four separate occasions.
SIRWA said because of these efforts, they were able to lift the advisory much earlier.
