Black and Veatch Consulting Engineers have estimated that Fountain's annual water requirement will increase to 10,000 acre-feet by 1990 and 15,000 acre-feet by 2020.

The communities annual use in 1972 was about 2,800; 2,000; and 2,100 acre-feet respectively. Black and Veatch Consulting Engineers (1973) have estimated that Security's, Widefield's and Stratmoor Hills' water requirements will increase to 6,398; 6,550; and 2,550 acre-feet respectively by 1990 and 9,780; 10,670; and 2,530 acre-feet respectively by 2020. D. Water Quality ;. The terminal storage point for Fryingpan-Arkansas project water is Pueblo Reservoir. This is the raw water supply for the proposed Fountain Valley Conduit. Project waters include both transmountain diversions from tributaries of the Fryingpan and Roaring Fork Rivers in western Colorado and native flows of the Arkansas River. The native flows of the Arkansas River are contaminated My numerous sources of ~ine drainage, which may contain high concentrations of various heavy metals.. In order to assess the impacts of these loadings, a study was conducted when the reservoir was first impounded (Herrmann and Mahan, 1976). Results are shoYn in Table 111-2. With the exception of those discussed below, me parameters measured were well within the recommended criteria for public water supply sources. i.e. raw water prior to treatment. Sulf9~e__c_~enL~atiQUs in Pu~Res~Qir pxceeded the rp~nmmen~e~ criterion for water supply sources in four samples during the 1974- 1975 sampling period (June to June). Three of the samples were collected on the same date and reflected similarly excessive sulfate concentrations throughout the water column. Tne other sample, which exhibited a concentration of 560. milligrams ?er liter sulfate, was collected near the reservoir bottom at 15 meters depth. This was the first year in which water was impounded by the dam. No excessive sulfate concentrations were observed in the 1975-1976 sampling year, when additional dilution waters were available. . 1II-13 ----. .,
