Mother Nature has a way of reminding us that humility is a trait that humans too often lack. Take, for instance, the engineering firm Knight Piesold, which stated that “modern dam design technologies are based on proven scientific/engineering principles and there is no basis for asserting that they will not stand the test of time.”
Until they don’t. Earlier this month a tailings dam designed by Knight Piesold at the Mount Polley copper mine breached, dumping up to 10 million cubic meters of heavily contaminated water into surrounding streams, rivers and lakes in central British Columbia. Since the accident aerial photographs show a massive mudslide attacking the tranquil waters of a nearby salmon stream and dumping into Quesnal Lake. The salmon run will most likely perish, along with the entire ecosystem that the salmon and other species rely on for life.
Even so, the company is probably off the hook. Full disclosure: The quotation at the beginning of this essay is not related to the Mount Polley mine; Knight Piesold offered up the above assurance in defense of the proposed Pebble mine in southwest Alaska.
The Pebble mine would be one of the largest mines ever built. The deposit is huge, with a market value ranging from $350 billion to $500 billion of copper and gold.
