This research improved the assessment and control of arsenic contamination. The limit was set at 10 micrograms per liter (µg/L), previously 50 µg/L. To help states meet these new standards, EPA researchers developed and evaluated innovative methods and cost-effective technologies. These demonstrations provided states and water utility operators with important information about removing ar

    Most arsenic removal technologies are most effective in removing the pentavalent form of arsenic (As(V), arsenate), since the trivalent form (As(III), arsenite) is predominantly non-charged below pH 9.2. Thus arsenate is much less mobile than arsenite, as it tends to co-precipitate out with metallic cations or to adsorb onto solid surfaces.
