'Treatment train' attacks algae at Grand Lake St. Marys

MONTEZUMA, Ohio – State and local officials said a site that uses natural and engineered methods to clean water for Ohio's largest inland lake has helped reduce chemicals that contribute to its toxic algae problem.

The Lima News (http://bit.ly/1c2aOFQ ) reported the site near Grand Lake St. Marys uses a pump station to move water through ponds and pools with different types of plants, organisms and rock barriers.

Grand Lake restoration manager Milt Miller said the so-called "treatment train" cleans more than 1 million gallons of water daily and cost about $1.4 million. Miller said five similar sites are planned around the western Ohio lake.

Officials also have used chemical treatments, dredging and farm outreach to significantly reduce phosphate levels that fed the toxic algae blooms that plagued the lake in recent years.
