THE QUARTER NOTE
THE ANIMAS RIVER IN COLORADO, NEW MEXICO, AND UTAH IS DEAD
The Animas River Is Dead - Heavy Metals
A strong statement, but not so far fetched when you consider that the River is contaminated with cadmium (probably responsible for its yellow color), lead, arsenic, beryllium, copper, aluminum, and mercury at concentrations that exceed the EPAs own safe maximum contamination levels.
The Animas River is Dead - Health Effects
Still a strong statement but note that the levels being measured in the water at this time present an immediate health problem for those using the water source for drinking and irrigating crops. Animals will also be affected. Most effects of heavy metals are not immediately experienced, but many of them result from the accumulation of heavy metals in the body which may produce chronic effects including kidney damage, central nervous system damage particularly in young people and newborns, and, indeed, cancer, among other effects. In essence, the Animas River is dead to those who seek to use it to survive.
The Animas River is Dead - No Practical Solution
While the river may be cleansed as some of the soluble metal salts are washed downstream into New Mexico and Utah, it is truly what is left behind that guarantees that the Animas is dead. When the EPA breached the dam holding back the 3 million gallons of contamination from the gold mine, the release obviously contained both soluble salts of heavy metals (measured by the EPA on August 5th and 6th,) but also the more long lasting "insoluble" salts and heavy metals. These insoluble salts will settle to the bottom of the River mixing with silt and other organic matter. There is no practical manner to remove these sediments, unless the entire Animas River is dredged. Even then, the disruption of the silt bed will send more heavy metal sludge further downstream.
