Systems (300) and methods are provided for the removal and disposal of arsenic from an aqueous medium. The systems (300) and methods include the removal of arsenic from a source by contact with either a chemically treated natural or synthetic zeolite (302), for example a ferric-loaded zeolite. The spent zeolite is disposed of at an appropriate arsenic disposal site (312). A system for monitoring (304) and maintaining an arsenic removal/disposal system by an off-site provider is also disclosed.
