Floating Islands


Water pollution is becoming a clear problem in the United States, due in part to farmers planting and maintaining their crops. In Upper Mississippi, nitrogen and phosphate from crop fertilizer has seeped into rivers and streams without it being filtrated naturally by the surrounding environment. Furthermore, this problem is also critical in Iowa, where the polluted water can reach the Gulf of Mexico, causing anything within 6,700 square miles to die and costing fisheries 2.8 billion dollars a year(Palmer). What can we do?

Preservationists have filed lawsuits against the Environmental Protection Agency to create stricter standards for phosphate and nitrogen runoffs (Palmer). Resulting from these lawsuits, farmers have created their own solution to the problem: floating islands. Floating islands would be used for filtration; the contaminated water would go through the islands and filtrate all the nitrogen and phosphate before it enters rivers. According to Charles Theiling, a hydrological specialist for the Army Corps of Engineers in Davenport, Iowa, these floating islands will mimic wetlands, which have done this for many years(Palmer).

By the way these islands are built from recycled soda bottles and grown with native plants from the area. Additionally, these floating islands will only serve a temporary solution to water contamination; there still needs to be a definite solution for this problem. However, a company called Floating Island International is probably trying to make floating islands part of the solution. This business has created floating islands the size of a backyard, called BioHaven (Palmer). They serve the same purpose as a normal floating island, but they are much bigger.

  1. This was a really interesting post! I had no idea that floating islands could filter the fertilizer waste in this way. Could you expand the text, perhaps, and explain to your readers how these floating islands work like wetlands? I wonder if it's safe for animals to interact with these floating islands? And how would a community get together to clean up the additional waste?

    One technical question I have is at number: 6,700 square miles. That's a huge swathe of territory. Are you saying that nothing grows in that area that's contaminated? Can you give a specific example/image of this?
