Horace Harmon Lurton,
Arizona Copper Company v. Gillespie…
“ The Arizona statute places a water user for mining purposes upon no higher plane than a user for irrigation. The suggestion that the right to use for mining and reduction purposes cannot be exercised without polluting the streams with waste material, tailings, etc., and that the lower user cannot, therefore, complain of the necessary consequences of the legal right conferred by statute, is without force. The only subordination of one water user to another is the right of the first appropriator to a sufficiency of water for his necessary uses. ”
