A-23 <br />TABLE 11 <br />CDOB Yampa Segment 13d (Dry Creek) and 13e (Sage Creek) Standards <br />I • <br /> <br /> <br />FIELD PH 6.5 - 9.0 <br />AMMONIA, NITROGEN, MG/L 0,13A <br />ARSENIC, TOTAL REC., UG/L 100.0 <br />BORON, DISSOLVED, UG/L 750.0 <br />CADMIUM, VG/L 9,1 (acute) <br />CADMIUM, VG/L 1.2 (chronic) <br />CHROMIUM, UG/L 1773 (acute) <br />CHROMIUM, VG/L 231 (chronic) <br />COPPER, UG/L 50.0 (acute) <br />COPPER, UG/L 29.0 (chronic) <br />IRON, TOTAL REC., MG/L 1.0 <br />LEAD, UG/L 281.0 (acute) <br />LEAD, UG/L 11.0 (chronic) <br />MANGANESE, MG/L 4.738 {acute) <br />MANGANESE, MG/L 2.618 (chronic) <br />MERCURY, TOTAL, UG/L 0.28 <br />NICKEL, IIG/L 1513.0 (acute) <br />NICKEL, IIG/L 168.0 (chronic) <br />NITRITE, NITROGEN, MG/L - 0.05 . <br />SELENIUM, IIG/L 18.4 (13e only, acute) <br />SELENIUM, UG/L 4.6 (13e only, chronic) <br />SELENIUM, UG/L 60.0 (13d only, acute/chronic) <br />SULFIDE, MG/L 0.02C <br />SILVER, IIG/L 22.0 (acute) <br />SILVER, UG/L 3.5 (chronic) <br />ZINC, MG/L 0.464 (acute) <br />ZINC, MG/L 0.405 (chronic) <br />Acute = one day max., Chronic = 30 day average. These values were <br />taken from Table IV, CDOH Reg. 31, using a mean hardness of 400 mg/1. <br />All 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 - 45% (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 />
