The data shall be summarized in <br /> such a manner as to illustrate clearly the compliance with this Order. If applicable, the Discharger <br /> shall notify the Board within 48 hours of any unscheduled shutdown of any soil vapor and/or <br /> groundwater extraction system. <br /> As required by the California Business and Professions Code Sections 6735, 7835, and 7835.1, all <br /> reports shall be prepared by a registered professional or their subordinate and signed by the <br /> registered professional. <br /> Semiannual reports shall be submitted to the Board by the 30th day of the month following the <br /> end of first and third calendar quarters (i.e., by 30 April and 30 October) until such time as the <br /> Executive Officer determines that the reports are no longer necessary. Each semiannual report is to <br /> include the following minimum information: <br /> (a) a description of the quarterly groundwater sampling events, including field logs. At a <br /> minimum, field logs shall contain water quality parameters measured before, during, and after <br /> purging, method of purging, depth of water, volume of water purged, etc.; <br /> (b) groundwater contour maps for the shallow and deep groundwater zones, if applicable; <br /> (c) isocontour contaminant concentration maps for all monitored groundwater zones, if applicable; <br /> (d) cumulative data tables containing the water quality analytical results and depth to groundwater; <br /> (e) a copy of the laboratory analytical data report; <br /> (f) if applicable, the status of any ongoing remediation, including cumulative information on the <br /> mass of contaminant removed from the subsurface, system operating time, the effectiveness of <br />
