These values were taken <br /> from Table IV, CDOH Reg. 31, using a mean hardness of 400 mg/l. All <br /> acute/chronic values are the 'dissolved' form. <br /> A = Standard is 0.06 mg/1 (un-ionized). Detection limit is 0.10 mg/1. <br /> Screening value = 0.13 mg/1 = .06 mg/1 _ 45a (max ionization at pH 9, <br />. 30° C) <br /> B = Standard is 0.01 ug/1. Detection limit is 0.2 ug/1. <br /> C = Standard is 0.002 mg/1 (un-ionized). Detection limit is 0.02 mg/1. <br />
