2 Beginning April 1,
				2016.
3 These 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.
