Explanation:

The most likely cause of this would be that both locations where toxic pollution was found were along the same river. The toxic spill that originated in Wyoming most likely found its way to the nearby river which after a while contaminatated the entire river which travelled all the way to Kansas. Therefore, contaminating the well which gets its water from the river. Such a river that travels near both of these locations is the Cheyenne River, therefore under these circumstances it would be relatively easy for both of these bodies of water to become contaminated with the same toxin.
