„-. �. <br /> MONITORING AND REPORTING PROGRAM ORDER NO.R5-2008-0149-010 5 <br /> PARKINSON'S HAMMER 1-5 ARCO <br /> SAN JOAQUIN COUNTY <br /> Constituent Method' Maximum Practical 2 Frequency <br /> Quantitation Limit(Ng/L) <br /> Fe12,Fe1',Se,CI,F,P EPA 200.7/SM3500-FeD/ 10 <br /> SM4500-P/300.0/6010 <br /> TDS EPA 160.1' 10 <br /> Or an equivalent EPA Method that achieves the maximum Practical Quantitation Limit. <br /> ' All concentrations between the Method Detection Limit and the Practical Quantitation Limit shall be reported as an estimated value(J flag). <br /> ' Dissolved metal analyses include As,Be,Ca,Cd,Cr,Co,Cu,Fe,Hg,Mg,Mn,Mo, Ni,Na,Pb,Sb,Tl,V.W,and Zn and are collected in <br /> laboratory-supplied non-preserved container,relinquished to the lab for filtering and preservation prior to analyses. <br /> ' Per previous SJCEHD directive,only well MW-1(and new wells)require BTEX analyses. <br /> FIELD SAMPLING <br /> 3. In addition to the above sampling and analysis, groundwater elevation, electrical <br /> conductivity, DO, ORP, pH, and water temperature will be measured in the field each time a, <br /> monitoring well is sampled. The sampling and analysis of field parameters is specified in <br /> Table 3. <br /> Table 3: Field Sampling Requirements <br /> Parameters Units Type of Sample <br /> Groundwater Elevation Feet,Mean Sea.Level Measurement <br /> Water Temperature Degrees Celsius Grab <br /> Electrical Conductivity uhmos/cm Grab <br /> Dissolved Oxygen mg/L Grab <br /> pH pH Units(to 0.1 units) Grab <br /> An ozone detection meter (field test instrument) will be used periodically in the breathing <br /> zones inside the remediation equipment area and at each. injection wellhead during <br /> maintenance and monitoring field activities. Field test instruments (such as those used to <br /> test pH and dissolved oxygen)may be used provided that: . <br /> 1. The operator is trained in proper use and maintenance of the instruments; <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 <br /> frequency; and <br /> 4. Field calibration reports are submitted as described.in item (b)of the"Reporting” section <br /> �I <br /> of this MRP. <br /> DISCHARGE MONITORING <br /> 4. The Discharger shall monitor the amendments- that are injected into the groundwater, <br /> measuring ozone gas injection rates during each site visit. Ozone as and H2Oz li uid <br /> injection shall be recorded, with information regarding the time period over which ,each,:- Deleted:the <br /> amendment was injected into the aquifer, infection.concentrations; and volumes of t7aS and <br /> I <br />
