Notes:
(a) The Gross Alpha Activity standard excludes alpha activity due to Radon and Uranium. The majority of the gross alpha count In these samples is
allnbutable to uranium and radon.
(b) Based on the sum of beta emitters present and a risk-based analysis of 2-fiters per day drinking water Intake.
(c) The standard of 5 p0VL is for combined Radium-228 and Radium-228.
(d) Uranium levels In the Laver Dolores River Basin cannot be Increased above-30 uSIL or background, whichever is greater.
(a) Numedc table values for Segment 3a of the L%Nw Dolores Riverwater quality standards.
(0 The Colorado Water (lushly Control Commission has calculated a health-based standard of 0.02 ugiL for arsenic.
"<' Indicates that the constituent was not detected at the specified reporting limit
Shading of a value Indicates that the concentration or activity level Is above one or more regulatory standards.
