Standard Operating GL-MA-E-013 REV# 21, GL-MA-E-016 REV# 9, GL-MA-E- <br /> 014 REV# 24, GL-MA-E-010 REV# 25 and GL-GC-E-107 <br /> Procedures: REV# 8 <br /> Analytical Method: EPA 200.7, EPA 200.8, EPA 245.1/245.2 and SM 2340 B <br /> Prep Method : EPA 200.2 and EPA 245.1/245.2 Prep <br /> Preparation/Analytical Method Verification <br /> The SOP stated above has been prepared based on technical research and testing <br /> conducted by GEL Laboratories, LLC. and with guidance from the regulatory documents <br /> listed in this "Method/Analysis Information" section. <br /> System Configuration <br /> The Hardness as CaCO3 is calculated from Calcium and Magnesium results. <br /> The Metals analysis-ICP was performed on a PE 7300 Optima radial/axial-viewing <br /> inductively coupled plasma atomic emission spectrometer. The instrument is equipped <br /> with a Burgener nebulizer, cyclonic spray chamber, and yttrium or scandium internal <br /> standard. Operating conditions for the ICP are set at a power level of 1500 watts. The <br /> instrument has a peristaltic pump flow rate of 1.4L/min, argon gas flows of 15 L/min and <br /> 0.2 L/min for the torch and auxiliary gases, and a flow setting of 0.65L/min for the <br /> nebulizer. <br /> The Metals analysis - ICPMS was performed on a Perkin Elmer ELAN 9000 inductively <br /> coupled plasma mass spectrometer(ICP-MS). The instrument is equipped with a cross- <br /> flow nebulizer, quadrupole mass spectrometer, and dual mode electron multiplier <br /> detector. Internal standards of scandium, germanium, indium, tantalum, and/or lutetium <br /> were utilized to cover the mass spectrum. Operating conditions are set at 140OW power <br /> and combined argon pressures of 360+/-7 kPa for the plasma and auxiliary gases, and <br /> 0.85 L/min carrier gas flow, and an initial lens voltage of 5.2. <br /> The Metals analysis-Mercury was performed on a Perkin-Elmer Flow Injection Mercury <br /> System (FIMS-100) automated mercury analyzer. The instrument consists of a cold vapor <br /> atomic absorption spectrometer set to detect mercury at a wavelength of 253.7 nm. <br /> Sample introduction through the flow injection system is performed via a peristaltic <br /> pump at 9 mL/min and nitrogen carrier gas rate of 80 mL/min. <br /> Calibration Information <br /> Instrument Calibration <br /> The instrument calibrations are conducted using the method and instrument <br /> manufacturer's specifications. All initial calibration requirements were not met for this <br /> SDG. 316524001 (Sunday 1) and 316524002 (Sunday 65)-ICP. These samples with QC <br /> were reran for potassium because that analyte failed in the initial calibration. 316524001 <br /> (Sunday 1) and 316524002 (Sunday 65)-ICP. <br /> Page 20 of 86 <br />
