The water that covers Geamana is laced with cyanide and other chemicals, making the area uninhabitable. Recently, the website Roadtrippers published several pictures from the abandoned village.

Unfortunately, the fate of Geamana is not uncommon. In the United States, the area around Treece, Kansas and Picher, Oklahoma was ranked in 1981 by the Environmental Protection Agency as the most contaminated in the country. The contamination was the result of extensive lead and zinc mining. In the 1920s, the area was the number one producer of the elements in the United States, supplying the metals for ammunition during the World Wars. While the metals were extracted, the waste was piled up around the town into mounds of contaminated gravel that still litter the landscape. A New York Times article from May 2012, describe the conditions:
