4 � • <br /> CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD <br /> CENTRAL VALLEY REGION <br /> MONITORING AND REPORTING PROGRAM NO. 91-220, Revision 1 <br /> KEARNEY-NATIONAL, INC. <br /> KEARNEY-KPF <br /> SAN JOAQUIN COUNTY <br /> Kearney-KPF is a manufacturer of high voltage switching devices. Waste disposal from the manufacturing <br /> process has resulted in ground water contamination with volatile organic compounds. A ground water <br /> extraction and treatment system has been in operation at the facility since 1992 with treated ground water <br /> being discharged to an injection well. Waste Discharge Requirements (WDRs) were adopted in 1991 for <br /> the treatment system. As part of the WDRs, Monitoring and Reporting Program (MRP)No. 91-220 <br /> established monitoring requirements for the startup and full-scale phases of the treatment system, <br /> extraction wells, observation wells, and injection well. This monitoring program revises MRP No. 91-220. <br /> GROUND WATER MONITORING <br /> There are 23 ground water monitoring wells, six piezometers, five extraction wells, one shallow supply <br /> well, and one injection well as shown in Figure 1. All annual monitoring shall be conducted during the <br /> quarter of highest anticipated ground water elevations. <br /> Prior to construction, plans and specification for ground water monitoring and/or extraction wells shall be <br /> submitted to Board staff for review and approval. After construction, new wells are to be sampled and <br /> analyzed for the constituents below and added to the monitoring program. <br /> Extraction Well Monitoring <br /> During extraction of ground water from extraction wells KI-3, KI-5, KI-6, KEW-3, and KEW-4 the <br /> following monitoring program shall be conducted: <br /> Type of Sampling <br /> Constituents Ui i Sample FreQuency <br /> Volatile Organic Compounds µg/l Grab Q <br /> (Method 8010 or 601) <br /> Electrical Conductivity (Field) µmhos/cm Grab Q <br /> Total Dissolved Solids mg/l Grab A <br /> pH(Field) pH units Grab Q <br /> Temperature (Field) Celsius Grab Q <br /> Total Volume of Water Extracted gallons Continuous Q <br /> Extraction Rate at Time of Sampling gpm Grab Q <br /> Average Extraction Rate(last 7 days) gpm Continuous Q <br /> Pressure at Time of Sampling psig Grab Q <br /> Water Level ft msl Grab Q <br />
