The residents of Carson, California, have had to endure weeks of a foul stench emanating from the Dominguez Channel. The smell, described by locals as similar to rotten eggs, was first reported on Oct. 3. Now, officials say that the stench was caused by waste from a beauty and wellness product warehouse that caught fire and spilled chemicals into a canal. The task of determining the cause of the “stench of death” was left to South Coast Air Quality Management District.
