R5-2005-0827 - 4 - <br />FORMER CONNELL MOTOR LIFT TRUCK <br />SAN JOAQUIN COUNTY <br />a description and discussion of the groundwater sampling event and results, including trends in the <br />concentrations of wastes and groundwater elevations in the wells, how and when samples were <br />collected, and whether the waste plume(s) is delineated; <br />field logs that contain, at a minimum, water quality parameters measured before, during, and after <br />purging, method of purging, depth of water, volume of water purged, etc.; <br />groundwater contour maps for all groundwater zones; <br />isocontour waste concentration maps for all groundwater zones; <br />a table showing well construction details such as well number, groundwater zone being monitored, <br />coordinates (northings and eastings), ground surface elevation, reference elevation, elevation of <br />screen, elevation of bentonite, elevation of filter pack, and elevation of well bottom; <br />a table showing historical lateral and vertical (if applicable) flow directions and gradients; <br />cumulative data tables containing the water quality analytical results and depth to groundwater; <br />a copy of the laboratory analytical data report; <br />if applicable, the status of any ongoing remediation, including cumulative information on the mass of <br />waste removed from the subsurface, system operating time, the effectiveness of the remediation <br />system, and any field notes pertaining to the operation and maintenance of the system; and <br />if applicable, the reasons for and duration of all interruptions in the operation of any remediation <br />system, and actions planned or taken to correct and prevent interruptions. <br />The 4th Quarterly Report of each year shall be an Annual Report submitted to the Regional Board by <br />1 February of each year.

The Annual Report shall contain, in addition to the information required <br />above for Quarterly Reports, the following minimum information: <br />graphical summaries of all data obtained during the previous year; <br />chronologically organized groundwater contour maps and waste concentration maps containing all <br />data obtained during the previous year; <br />a discussion of the long-term trends in the concentrations of the wastes in the groundwater monitoring <br />wells; <br />an analysis of whether the waste plume is being captured by the remediation system(s) or is continuing <br />to spread;
