    1These arsenic values are effective January 1, 2006. Until then, the MCL is 0.05 mg/l and there is no MCLG.

    Key:

    AL = Action level.

    MCL = Maximum contaminant level.

    MCLG = Maximum contaminant level goal.

    MFL = Million fibers per liter.

    MRDL = Maximum residual disinfectant level.

    MRDLG = Maximum residual disinfectant level goal.

    mrem/year = millirems per year (a measure of radiation absorbed by the body).

    N/A = Not applicable.

    NTU = Nephelometric turbidity units.

    pCi/l = Picocuries per liter (a measure of radioactivity).

    ppm = Parts per million, or milligrams per liter (mg/l).

    ppb = Parts per billion, or micrograms per liter (μg/l).

    ppt = Parts per trillion, or nanograms per liter (ng/l).

    ppq = Parts per quadrillion, or picograms per liter (pg/l).

    TT = Treatment technique.
