The  method includes the step of contacting the ion exchange  material with an aqueous process fluid to yield a regenerated  ion exchange material. At least one target material associ› ated with the resin is removed. The target material includes  at least one of the following: metal ions such as those that  have been extracted from a source of hard water, ionically  soluble organic compounds, active water borne pathogens.
