CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD <br /> CENTRAL VALLEY REGION <br /> MONITORING AND REPORTING PROGRAM NO. <br /> FOR CLOSURE OF <br /> KEARNEY-KPF <br /> SURFACE IMPOUNDMENTS <br /> SAN JOAQUIN COUNTY <br /> SURFACE WATER MONITORING <br /> The ditch which borders the western property boundary shall be sampled when it <br /> contains representative surface water runoff from the field. A sample shall be <br /> collected from the southern portion of the ditch which borders the on-site <br /> disposal areas and is adjacent to the lowest surface elevations of the field. <br /> The sample shall be collected during the first storm of the rainy season which <br /> produces significant flows. Surface water samples shall be analyzed for the <br /> following: <br /> Report in <br /> Parameter/Constituent Units of <br /> Specific Conductance(field) umhos/cm <br /> pH (field) pH units <br /> GROUND WATER MONITORING <br /> The following monitoring program shall be implemented at the facility to <br /> determine compliance with "water quality protection standards". Because the <br /> direction of ground water movement in the aquifer fluctuates during the year from <br /> east to west, monitor wells are to be located in such a manner as to surround <br /> the closed units. The locations of the wells are shown an Attachment B. Samples <br /> from all monitoring wells shall be analyzed for the following parameters and <br /> constituents at the identified frequencies. <br /> Sampling <br /> Report in & Reporting <br /> Parameters/Constituent Units of Frequency <br /> Specific Conductance (field) umhos/cm Quarterly <br /> Specific Conductance umhos/cm Annually <br /> pH (field) pH Units Quarterly <br /> pH pH Units Annually <br /> Temperature (field) OF Quarterly <br /> Total Dissolved Solids mg/l Annually <br /> Chloride mg/l Annually <br /> Sulfate mg/l Annually <br /> Carbonate mg/l Annually <br /> Bicarbonate mg/l Annually <br /> Alkalinity mg/l Annually <br />
