Contamination
In 2003, traces of lead were discovered in schoolchildren who lived in the nearby village and had dranken from the water. This was believed to be caused by the nearby Tatasi-Portugalete Mine, which was mining for silver and lead. Because of this, COMNIBOL (Bolivia's state mining corporation) and the Danish environmental cooperation program (PCDSMA) invested $654,000 into fixing the canals and waterways in the area to make it safer. The mining and hydrocarbons minister, Jorge Berindoague, officially opened the project in late 2003. The project was designed to make the water safe within five years.
