(a)	Arsenic	0.010 [FN**]
(b)	Asbestos	7 Million Fibers/liter (longer than 10/m)
(c)	Barium	2.0
(d)	Cadmium	0.005

(3) At the discretion of the Department, nitrate levels not to exceed twenty milligrams per liter may be allowed in a non-community water system if the supplier of water demonstrates to the satisfaction of the Department that:

(a) Such water will not be available to children under six months of age; and,

(b) The non-community water system is meeting the public notification requirements under R.61-58.6.E(9), including continuous posting of the fact that nitrate levels exceed ten milligrams per liter and the potential health effects of exposure; and,
