On March 11 of this year, the Canadian mining company First Majestic Silver Corp spilled 200 litres of a cyanide solution from the San Dimas project into the Piaxtla River in Durango, Mexico. The spill of the solution - representing roughly 100 to 180 mg of cyanide - apparently occurred when a truck carrying the deadly chemical ran out of fuel on a hill. An employee either failed to close a valve, or the valve itself was faulty.

An environmental organization named Conselva y Voces Unidas por el Agua, which has its offices in Mazatlán, Sinaloa, has demanded a valid environmental assessment of the environmental impact of the spill. One month after the spill, that does not appear to have happened.
“The damage to the ecosystem has to be evaluated – if it filtered to the subsoil, and affected the water table, which supplies the community with water,” said the executive director of Conselva, Sandra Guido, shortly after the spill was reported.
