The illustration above is not a true representation of scale.  Class I injection wells can be extremely deep (more than 1,000 ft, typically several thousand to ten-thousand feet in depth).  These wells penetrate below many rock layers and are carefully sited and designed so as to not contaminate shallow usable fresh-water.
