2.04.7(1) GROUND WATER INFORMATION • At least 20 wells exist within a mile radius of the Pryor Permit Area, These are plotted in Figure 2.04.5-5 and records derived from the State Engineers office tabulated in Table 2.04.5-2. Additional information was also gathered from Mr. Samuel J. Capps (Tables 2.04.7(1)-1, 2,04.7(1)-2 and 2.04.7(1)-3), Mr. Larry Vezzani (Table 2.04.7(1)-4) and Mrs. Mary Ann Vigna (Tables 2.04.7(1)-5 and-6) on additional wells in the area. Mr. Vezzani's well was further sampled, and water quality and level measurements carried out in the field (Table 2.04.7(1)-7). Most of the old wells are abandoned and in disuse. Information on well completion, casing, well depth, water level and water quality is scant. The few water quality analyses provided by the above mentioned local residents show that the ground water in the area is high in alkalinity and total dissolved solids making it unfit for drinking or irrigation. Although the record is not clear, it would be safe to assume that most of the wells that struck water in the area tap the Trinidad Sandstone as this is the only potential confined aquifer in the Pryor Permit Area and adjacent area • within the depths given for the wells, Within the permit area the top of this formation outcrops in discontinuous fashion between the confluence of Pryor Canyon and the unnamed drainage and the Black Hawk Canyon just east of the bridge in the southeast corner of the permit area (Revised Map 3). In the 1982(2) partial permit area depths to the top of the Trinidad Sandstone are less than 70 feet. At such shallow depth and within less than 500 feet from the outcrop the likelihood of ground water occurrence is minimal, The well drilled for monitoring purposes has also confirmed the absence of ground water at the expected depth of mining, The siting of monitor well No. 296519-1 (See Revised Map 3) was based on the understanding that at this stage, monitoring is needed for only the 1982(2) Partial permit area. This ground water description is therefore relevant only to this particular partial permit area. The well was thus sited down dip from.the future mine pit in order to intercept water passing through the pit. Mapped faults to the west were noted to avoid coming between the monitor well and the mine pit. Other faults may, however, exist within the mining area (See Figure 2.04.7(1)-1). The monitor well is located 100 feet west of the western boundary of the r 1 JFSA_21 ~ " 1 2 1 ~, E shin ~ nssnr~~s„ iNC.
