<br />D-I <br /> <br /> <br />" "', 0 3 <br />UUL_tO.: <br /> <br />WATER QUALITY <br /> <br />Surface Water Quality <br /> <br />The mainstream South Platte River and its major tributaries exhibit wide <br />variations in water quality. A general conclusion is that average <br />concentrations of dissolved solids and major ions tend to increase in the <br />mainstream South Platte River from Henderson to Julesburg. This is felt to be <br />the combined effect of water re-use, increased use for irrigated agriculture, <br />and percolation of return flows through sedimentary soils. Table D-1 shows a <br />summary of stream quality at selected locations. <br /> <br />Groundwater Quality <br /> <br />Water pumped from the valley-fill alluvium is characterized by dissolved <br />solids concentrations ranging from 100 to 4,000 mg/1, indicating a range from <br />acceptable to impaired water quality. Available groundwater qualtiy maps show <br />total dissolved solids content to be between 500 to 1000 mg/1 along the Platte <br />River between Denver and the St. Vrain Creek confluence. From there to the <br />State line the quality is between 1,000 and 2,000 mg/l. There are localized <br />areas with groundwater quality at 2,000 to 4,000 mg/l. <br />
