Ground water monitoring in the permit and adjacent areas will involve measurement of ground water levels on both a <br />semi-annual and quarterly basis and collection of ground water physical data and the sampling and analysis of <br />.ground water chemical constituents on both asemi-annual and quarterly basis. Ground water monitoring activities <br />will encompass bedrock ground water and shallow alluvial ground water. The monitoring well locations are shown <br />on the Hydrologic Monitoring Plan Map (Map 13A). <br />Semi-annual ground water sampling of bedrock wells and quarterly sampling of alluvial wells will involve <br />measurement of ground water temperature, pH, and electrical conductivity and collection of the necessary samples <br />for chemical analysis. Standard EPA calibration and measuremcnt methods will be used for all ground water <br />measurements in the field. Acceptable techniques +vill be used to ensure the collection of representative ground water <br />samples from wells. Water samples will be analyzed by a qualified laboratory using standard ASTM or EPA <br />approved test procedures. Ground water analysis will involve measurement of the selected parameters and chemical <br />constituents listed in Exhibit l4, Hydrologic Monitoring Plan. <br />A 1995 water monitoring well was drilled to replace FCMN2, which has failed. The well, 95M005, will monitor the <br />Trout Creek sandstone. After completion of the +vell the site was reclaimed, the topsoil replaced and the site reseeded <br />with the appropriate seed mixture. <br />Surface Water Monitorine <br />Surface water monitoring will address the quality and quantity of area streamflo+vs. Collection of the necessary <br />monitoring information will involve the following activities: <br />Sampling and wllection of flow and field parameters, 12 per year, during the period of March through September. <br />Collection of four samples per year for full suite analysis. <br />.Typically, flow measurements will extend from March into September. This period corresponds with the beginning <br />of the major runoff period and continues into the low flow period. The measurement frequency is given in Exhibit <br />14, Hydrologic Monitoring Plan. <br />Continuous measurements of streamflow and water stage data for Foidel and Middle Creeks will be available from <br />surface water gauging stations maintained by USGS-WRD.
