The barges are docked, the hoses are separated, and in general the alum application equipment at Grand Lake St. Marys is ready to be put in storage.
Employees for HAB Aquatic Solutions unloaded the final dose of alum on the lake Monday afternoon.
"The application went flawlessly. We didn't have any problems at all. We were well under schedule," said John Holz, water quality specialist, HAB Aquatic Solutions.
This is the second year in a row water quality specialists from HAB completed the process to control toxic algae blooms. The blooms led to health advisories and warnings at the tourist destination. Lake officials hope the application will lead to a summer free of those advisories.
"People who haven't been here come back. It is a good thing to know that at least we're getting off on a good good foot this spring," said Brian Miller, Grand Lake St. Marys State Park Manager.
The $5 million process also became the largest application of alum in the world.
"We got the full dose in the lake in the specified areas. It should be set and ready to start binding that phosphorous now," said Holz.
Last year's alum application, which was smaller in scope, was successful in reducing blooms on the lake. This year's results won't be known until testing is complete later this summer.
The cleanup process should be finished by Thursday.
