These samplings were conducted during March, June, September <br />and December. Semiannual water quality analyses were conducted during the June and December <br />samplings. Well sites in the Stollsteimer Alluvium were sampled quarterly for water level and <br />semiannually for water quality following thew installation in August 1993. <br />METHODS <br />During visits to each station, flow measurements were made by stretching a 100 foot tape across <br />a surveyed cross-section of the creek and checking cross-section depth. Velocity was also checked <br />to determine the flow rate. Water quality was collected by grab samples at each station. <br />Depth to water was measured in groundwater wells to the nearest hundredth of a foot using an <br />electric line. Groundwater samples were collected with a hand bailer after evacuating three casing <br />volumes of water. <br />During samplings for water quality, temperature was measured in the field with a hand <br />thermometer. All other parameters were collected in precharged bottles and submitted to <br />' Chemtech Laboratory i^ Salt Lake City for analyses. Methods of analysis were consistent with <br />EPA standazd testing procedures. <br />' SURFACE WATER <br />Results of all surface water measurements made during 1985 through 1995 are contained in <br />Appendix 1. A summary of major chemical parameters and flow is presented in Table 1. <br />' Flow data collected at the surface stations on Stollsteimer Creek during 1995 varied from 2.15 cfs <br />at station S-3 in September to a high of 76.7 cfs at station S-2 in March. As indicated from the <br />flow records, 1995 was a typical water yeaz with high flows in the spring and eazly summer and <br />' low flows during fall and winter. <br />' Recorded flows over the eleven year period ranged from a low of 0 cfs at station S-1 to a high of <br />195 cfs at station S-1 in March 1985. Maximum recorded flow was approximately 300 cfs during <br />April 1986, which was estimated at the mine haul road culvert crossing. In terms of average <br />' flow, 1985 was the highest and 1989 was the lowest. Spreadsheets and graphs of flow recorded <br />at each station are presented in Appendix I. <br /> <br />1 <br /> <br />1993.033/3/01-30.96(/2:38pm) <br />4 <br /> <br />
