    ICP-OES instruments used to analyze mining waste from abandoned copper mines

    lead_river_000047850534smallLess than 40 years ago in 1978, the Communist dictator of Romania ordered the 400 families living in the small village of Geamana to leave their homes so that the country could build a copper mine. Unfortunately, the people did not have much choice as the village was to become an artificial lake for the toxic waste from the Rosia Poieni, one of Europe’s largest copper mines. 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:

    “The towers are another problem in town. Some of them are 200 feet tall, and their dust, which on breezy days blows across the prairie, still contains enough metal to make blood-lead levels among young children here three times higher than the national average.

    “Then there’s the water. The local Tar Creek is the color of orange juice, and it smells like vinegar. This is because when the mining companies left, they shut off the pumps that kept abandoned shafts from filling with groundwater. Once water flooded the tunnels, it picked up all the trace minerals underground — iron, lead and zinc — and flushed them into rivers and streams. Fish and fowl fled or went belly-up.”[i]

    According to the EPA, there are 112 sites like Treece in the United States, including Jefferson, N.C., which is home to an eroding dam holding back mining waste from abandoned copper mines; Spokane Indian Reservation in Washington State, where piles of toxic rock remain from uranium mining; and the Berkley Pit in Butte, Montana, which closed in 1982, but now contains a lake of rainwater mixed with arsenic, sulfuric acid and cadmium.  While the remnants make for fascinating photo logs and case studies, some are growing in size and their impacts may yet be fully evident.

    Leeman Labs’ technology and instruments are used across the country and around the world to understand the level of contamination from these types of industrial sites and accidents so that the appropriate attention can be given towards prevention, cleanup and restoration. While contamination at these areas will be difficult to reverse, containing their pollution will be critical to prevent other areas, whether downstream, downhill or downwind, from suffering similar fates.
