For most of the 20th century, this was one of the largest copper mines in the British Empire - tunnels honeycombed Mount Sheer, men worked in conditions that killed them young, and the tailings flowed straight into Howe Sound. When the mine closed in 1974, nobody cleaned up. Acid mine drainage - water filtering through ore bodies, picking up copper, zinc, and sulfuric acid - poured from the mountain at 500 liters per minute. The sound became a dead zone. Britannia Creek ran orange. The pollution continued for thirty years until a treatment plant was finally built, a perpetual machine that will process toxic water for as long as the mountain bleeds.

Britannia Mine opened in 1904 and grew into a company town - 1,200 people living in bunkhouses and family homes on a mountain that wanted to kill them. The ore was rich; the conditions were brutal. Silicosis killed miners slowly; cave-ins killed them fast. In 1915, a massive snow...

At Britannia, this acid mine drainage ran unchecked for a century. Britannia Creek turned orange with dissolved copper. Howe Sound's marine life died for miles. The conta...

The plant intercepts acid mine drainage before it reaches the sound, treating 500 liters per minute with lime to neutralize the acid and precipitate the metals. T...
