MONITORING AND REPORTING ORDER NO.R5-2010-0818 - 3 - <br /> BP AMERICA AND APPLIED AEROSPACE STRUCTURES CORPORATION <br /> STOCKTON, SAN JOAQUIN COUNTY <br /> 1. Conduct monitoring and reporting in compliance with the following specifications. <br /> 2. As shown in Figure 1 , there are 15 monitoring wells, 7 (seven) groundwater <br /> extraction wells, and 3 (three) observation wells associated with the site. The <br /> Monitoring Program for these 25 wells and any wells installed subsequent to the <br /> issuance of this Order shall comply with the schedule and analytes in Table 1 and <br /> Table 2 below. <br /> TABLE 1: SAMPLING SCHEDULE <br /> Semi-annually Annually Not Sampled <br /> Wells MW-6, MW-15, MW-4, MW-5R, MW-7, MW-2, MW-3, GW-1 , <br /> MW-16, MW-17, MW-9, MW_10, MW_11, GW-2R, GW-3, GW-4, <br /> MW-12, MW-13, MW-14. GW-5, GW-6, GW-7, OB- <br /> 1, OB-2, OB-3 <br /> All wells shall be monitored semi-annually for Depth to Groundwater. <br /> 2 Wells that must be sampled semi-annually shall be sampled during the first and third <br /> quarters. <br /> Wells that must be shall be sampled annually shall be sampled during the third quarter. <br /> 4 Wells not sampled shall be measured for depth to groundwater. <br /> TABLE 2: ANALYTICAL METHODS <br /> Constituents EPA Analytical Maximum Practical <br /> Method Quantitation Limit ' <br /> Depth to Groundwater --- --- <br /> Electrical Conductance Field Meter 0.001 mmhos/cm <br /> pH Field Meter 0.01 units <br /> Temperature Field Meter 0.1 °C <br /> ORP Field Meter 1 mV <br /> Dissolved Oxygen Field Meter 0.01 mg/I <br /> VOCs 8260B 0.5 µg/I <br /> For nondetectable results. All concentrations between the Method Detection Limit and the <br /> Practical Quantitation Limit shall be reported as trace. <br /> 3. Monitoring wells with free product or a visible sheen shall be monitored at a <br /> minimum for product thickness and depth to water. <br />
