This powerpoint presentation begins by listing common inorganics, and then listing "other" inorganics. The methodology for designing a survey is provided, and the survey strategy of looking for under-addressed issues is outlined in detail, along with the methodology of conducting the survey, and results of the "Other" Inorganics are listed. Constituent groupings are listed, along with an overview of responses and issues by state, iron and manganese problems and treatment, other constituents observations, and treatment processes utilized. Conclusions: iron and manganese are the main "Other" inorganics of concern; fluoride, antimony, pH adjustment, hardness, perchlorate, and anions are also "Other" inorganics of concern; and, surprisingly, lead and copper weren't an issue, although corrosion control was a concern. Includes figures.
