CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD
<br /> CENTRAL VALLEY REGION
<br /> MONITORING AND REPORTING PROGRAM NO. 115-2003-0166
<br /> FOR
<br /> CONTIGROUP COMPANIES
<br /> FRENCH CAMP GRAIN ELEVATOR
<br /> ENHANCED BIOREMEDIATION PILOT STUDY
<br /> SAN JOAQUINCOUNTY
<br /> This Monitoring and Reporting Program (MRP) incorporates requirements for monitoring the
<br /> progress of the enhanced bioremediation pilot study. This MRP is issued pursuant to California
<br /> Water Code Section 13267. ContiGroup Companies (Discharger) is required to comply with this
<br /> MRP. The Discharger shall not implement any changes to this MRP unless and until a revised MRP
<br /> is issued by the Executive Officer. Groundwater sampling and reporting outlined in MRP
<br /> No. 5-00-858 is still required.
<br /> All samples shall be representative of the volume and the nature of the discharge and matrix of the
<br /> sampled medium. The time, date, and location of each grab sample shall be recorded on the sample
<br /> chain of custody form.
<br /> ENHANCED BIOREMEDIATION PILOT STUDY MONITORING
<br /> As shown on Attachment B, there are 14 monitoring wells, one proposed monitoring well, and two
<br /> private supply wells. The private wells are no longer in use. Monitoring of the enhanced
<br /> bioremediation pilot study HRC® injections will consist of groundwater samples collected from the
<br /> newly installed monitoring well (about eight feet downgradient from MW-3B), MW-3B, and
<br /> MW-4B. These analyses shall be completed by a State certified laboratory and shall follow
<br /> standard EPA protocol. Monitoring well samples shall be analyzed for the following constituents
<br /> and parameters and follow the schedule in the table below.
<br /> Constituents EPA Method Maximum Quantitation Limits Frequency
<br /> Depth to Groundwater --- 0.01 ft Monthly,
<br /> Volatile Organic Compounds 8260B 0.5 µg/1 Quarterly,
<br /> Lactic acid' IC-001 1.0 mg/l Monthly,
<br /> Ferrous and Ferric Iron' 200, 6020, or SM 3000 0.1 mg/1 Bi-monthly,
<br /> Carbon dioxide(dissolved)' SM 4500 or ASTM D1945 0.01 mg/l Bi-monthly,
<br /> Methane(dissolved)' RSK 175M or ASTM D1945 0.01 mg/1 Bi-monthly,
<br /> Total Organic Carbon' 415, 9060, or SM 5310 1 mg/l Bi-monthly,
<br /> General Minerals''4 Various Various Bi-monthly,
<br /> Metals'" Various Various Bi-monthly,
<br /> ORP and Dissolved Oxygen' Monthly,
<br /> For nondetectable results
<br /> , Monitoring of MW-4B shall begin after there is evidence of HRC®in the newly installed well(downgradient of MW-3B).
<br /> ' Baseline samples shall be collected a minimum of two weeks prior to injection.
<br /> 4 General Minerals include alkalinity,pH,electrical conductivity,total dissolved solids,calcium,chloride,copper,iron,
<br /> magnesium,manganese,sodium, sulfate,nitrate,and zinc.
<br /> 5 Metals include antimony,arsenic,beryllium,cadmium,bivalent and hexavalent chromium,cobalt,lead,mercury,
<br /> molybdenum,nickel,selenium,silver,thallium, and vanadium
<br /> ' Oxidation-reduction potential and dissolved oxygen are field measured parameters.
