Classifications and Numeric Standards for Upper Colorado River Basin and North Platte River,3.3.0. November 30,1994. Calculated surface water standards are based on the most conservative value of hardness=658 mg/L as CaCO3(sample SW-2). (2) Acute and Chronic water quality standards are below the MDL and/or the PQL. Analyte is not classified as an exceedance as it was not detected. (3)Acute water quality standard is calculated based on water temperature and pH. d type indicates exceedances of the Colorado Department of Health,acute and/or chronic surface water standards. =Not Available. CDH has no water quality standard for this parameter. Environmental ay��KIo3-0UI.WAL\L599rv6
