Notes:
(a) The Gross Alpha Activity stantlartl exUudes alpha activity tlue to Radon antl Uanium. The majority of the gross alpha count in these samples is
attritwtable to uranium antl ratlon.
(b) Based on the sum of beta emitters present and arisk-based analysis of 2-liters per day drinking water intake.
(c) The stantlaro of 5 pCUL is for combined Radium-226 and Ratlium-228.
(tl) Uranium levels in me Lower Dolores River Basin cannot be increased above~30 ug/L or background, whichever is greater.
(e) Numedctable values for Segment 3a W the Lower Dolores River water quality standards.
(~ The Coloretlo Water Quality Control Commission has calaWted a healm-basetl standard of 0.02 ug/L roc arsenic.
'r' irdicates that me constituent was not detected at the spedfie0 reporting limb.
Shading of a value indicates mat me concentration or activity level is above one or more regulatory stardards.
