Impact of copper mining on a desert intermittent stream in central Arizona: a summary

, : Impact of copper mining on a desert intermittent stream in central Arizona: a summary. Journal of the Arizona Nevada Academy of Science 14(1): 22-29

The initial impact of a large copper mine on biotic survival in a small desert stream in central Arizona was studied over a two-year period. The reduction in stream quality clearly indicated the hazards of mining activities to the biota. Sedimentation, the primary detrimental effect, eliminated much of the biota, reduced primary production, and altered a normal habitat by reducing water depth and filling the interstices between rock and gravel with a "cement-like" sediment.
