MONITORING AND REPORTING OER NO.R5-2012-XXXX -6- 1904 CHARTER WAY STOCKTON,SAN JOAQUIN COUNTY Footnotes to Table 3. 'An equivalent method may be used provided Practical Quantitation Limit for undetected compounds is comparable. "If the maximum practical quantitation limit is exceeded for a non-detectable result, the Discharger shall provide an explanation in the report text. All concentrations between the Method Detection Limit and the Practical Quantitation Limit shall be reported as trace. 5The reporting limit for MCPP and MCPA is 500 ug/L. 6The method to analyze 1,2,3-Trichloropropane should be selected such that the reporting limit is below the expected concentrations, based on recent monitoring results. 3. Monitoring wells with free product or a visible sheen (if applicable) shall be monitored at a minimum for product thickness and depth to water. Reporting Specifications 4. When reporting data, the Discharger shall arrange the information in tabular form so that the date, the constituents, and the concentrations are readily discernible and shall summarize the data in such a manner as to illustrate clearly the compliance with this Order. 5. As required by the California Business and Professions Code sections 6735, 7835, and 7835.1, all reports shall be prepared by a registered professional or their A subordinate and shall be signed by the registered professional. 6.

Each report shall include the following minimum information: (a) A description and discussion of the groundwater sampling event and results, including trends in the concentrations of pollutants and groundwater Jk elevations in the wells, how and when samples were collected, and whether the pollutant plume(s) is delineated. (b) Field logs that contain, at a minimum, water quality parameters measured before, during, and after purging, method of purging, depth of water, volume of water purged, etc. (c) Groundwater contour maps for all groundwater zones, if applicable.
