' GROUND WATER MONITORING <br />Water levels and water quality samples were collected four <br />times during the year. The frequency was May, June, August and <br />October. <br />' Samples are collected at the following wells: <br />' H-10 Groundwater well established on the pad of the Upper <br />Hubbard Creek facilities. <br />' B-6 Groundwater well established in former power hole along <br />Bear Creek. <br />' METHODS <br />' During visits to each station, water level measurements were <br />made using a Soil-Test Indicating Depth Meter with a conductance <br />bridge. Levels were recorded from the top of the well casing and <br />reported as elevation. <br />' Water quality samples were also collected four times. <br />Samples were obtained with a hand bailer. Parameters of <br />' temperature, pH, eH and conductivity were made in the field. All <br />sampling equipment and handling procedures were consistent with <br />those described in the surface methods section of this report. <br />1 <br />RESULTS <br />Results of well water measurements collected during 1986 and <br />1987 are presented in Appendix 1 and summarized in Table 1. <br />' Graphs of the pertinent water quality parameters are also shown in <br />Appendix 1. <br />Water level of Well H-10 remained constant for the first two <br />' samplings and than rose slightly over the last two samplings. <br />These elevations are approximately 8 feet above those taken during <br />1986. Water quality also remained consistent with that measured <br />' during 1986. The ground water is primarily a sodium-bicarbonate <br />type with a high degree of mineralization (see Trilinear diagram <br />in Appendix 1). Concentrations of TDS, conductivity, oil and <br />grease, alkalinity, ammonia, fluoride, arsenic, boron and iron all <br />' remained elevated over each of the samplings as was observed in <br />the 1986 data (Appendix 1). <br />
