II. WATER QUALITY SAMPLING <br /> Sampling of subsurface water from monitoring wells was conducted <br /> ' using a one liter PVC bailer. Five bailer volumes were typically <br /> removed prior to sampling of the well water. <br /> SMW-I, AMW-I, FPW, 96 and 122 are field and lab sampled quarterly. <br /> AMW-2 is also checked but remains dry at this time. The <br /> parameters monitored are as follows: <br /> Calcium-dissolved <br /> Iron-dissolved <br /> Magnesium-dissolved <br /> Manganese-dissolved <br /> Molybdenum-dissolved <br /> Sodium-dissolved <br /> Alkalinity, total (as CACO3 to pH 4.5) <br /> Carbonate (as CO <br /> g) <br /> Hardness (as CACO33) <br /> Bicarbonate (as HCO3) <br /> PH (pH units) <br /> Specific conductance (mmhos/cm) <br /> Lead-dissolved <br /> Selenium-dissolved <br /> Total dissolved solids (at 180°C) <br /> Chloride <br /> Sulfate (as SO4) <br /> SAR <br /> Wellsite readings of PH, EC, temperature (°C) and water level <br /> are recorded. Water levels are measured from top of casing and <br /> recorded prior to bailing. <br /> Electrical conductivity is measured in units of micro siemens per <br /> cm. The conductivity meter used measures the electrical <br /> conductivity at the sample temperature, which is set automatically <br /> by the meter. The pH meter is calibrated each quarter by testing <br /> with a standard solution of 7.0 PH. <br /> Page 7 <br />
