Kellogg Garden Products ECO:LOGIC Engineering <br /> Groundwater Monitoring Well Installation Work Plan KELG04-001 <br /> 11/10/2004 <br /> SURVEYING <br /> The locations of each well and piezometer will be surveyed and located according to the California State Plane <br /> Coordinate System, 1983 horizontal datum. The elevations of the north quadrant of the PVC well casing will <br /> be surveyed to within 1/100" of a foot accuracy relative to NGVD29 or NAVD88. Adjacent ground surface <br /> will also be surveyed for reference. <br /> Care shall be exercised during surveying to avoid introduction of foreign material into the wells. Rod or <br /> receiver bottoms shall be wiped with a chlorine solution prior to setting on well casing for each well. <br /> SOIL SAMPLING <br /> No soil samples are required other than those used to classify the geologic materials penetrated by the <br /> boreholes. <br /> Spoil from drilling will be dispersed at the facility. <br /> WELL SAMPLING <br /> The initial water sample from the wells will be collected 48 hours or longer after development has been <br /> completed. Subsequent well sampling performed pursuant to the Monitoring and Reporting Requirements <br /> (MRPs)of the Waste Discharge Requirements will be collected according to the following procedure. See the <br /> MRP for the frequency of sampling. <br /> When a water sampled is collected,under the MRP, the following measurements will be made: <br /> Depth to Groundwater <br /> Groundwater Elevation(calculated based on depth to groundwater) <br /> Gradient <br /> Gradient Direction <br /> Water samples collected will be submitted to a state certified laboratory for analysis of the following <br /> constituents according to appropriate EPA and approved methods: <br /> pH <br /> Total Dissolved Solids <br /> Total Coliform Organisms <br /> Nitrate as Nitrogen <br /> Total Kjeldal Nitrogen <br /> Standard Minerals'including: <br /> Chloride <br /> Magnesium <br /> Sodium <br /> Total Alkalinity including alkalinity series <br /> Hardness <br /> Calcium <br /> Potassium <br /> Sulfate. <br /> 'Standard Minerals to be analyzed in the fourth quarter <br /> Pur in <br /> A minimum of three well volumes will be purged from the well prior to sampling. Purging will be <br /> accomplished by pumping with a portable pump or by manually bailing. Field water quality parameters <br /> 7 <br />
