R5-200X-XXXX 3 <br /> DISCHARGER NAME r <br /> COUNTY <br /> s Metals include barium cadmium, calcium, total chromium, copper, lead, magnesium, <br /> manganese, mercury, molybdenum, nickel and silica. <br /> FIELD SAMPLING <br /> In addition to the above sampling and analysis, field sampling and analysis shall be conducted each time <br /> a monitor well or extraction well is sampled. The sampling and analysis of field parameters shall be as <br /> specified in Table 3 . <br /> Table 3 : Field Sampling Requirements <br /> Parameters Units Type of Sample <br /> Groundwater Elevation Feet, Mean Sea Level Measurement <br /> Oxidation-Reduction Potential Millivolts Grab <br /> Electrical Conductivity uhmos/cm Grab <br /> Dissolved Oxygen MgJL Grab <br /> H pH Units to 0. 1 units Grab <br /> Field test instruments (such as those used to test pH and dissolved oxygen) may be used provided that: <br /> 1 . The operator is trained in proper use and maintenance of the instruments; 9 <br /> 2. The instruments are calibrated prior to each monitoring event; <br /> 3. Instruments are serviced and/or calibrated by the manufacturer at the recommended frequency; <br /> and <br /> 4. Field calibration reports are submitted as described in item (b) of the "Reporting" section of this <br /> MRP. <br /> DISCHARGE MONITORING <br /> The Discharger shall monitor daily the discharge of water and amendments that are injected into the <br /> groundwater according to the requirements specified in Table 4. Each amendment addition shall be <br /> recorded individually, along with information regarding the time period over which the amendment was <br /> injected into the aquifer. <br /> Table 4: Discharge Monitoring Requirements <br /> Parameters Units Type of Sample <br /> Injected Volume gallons per day Meter <br /> Amendments Added kilograms per day Measured <br /> Biocide Added kilograms per day Measured <br />
