1 <br /> 1 <br /> Fuller Mobile Home Park <br />' 365 East Louise, Lathrop, California <br />' Quarterly Groundwater Sampling Report <br /> July, 1995 <br /> 1 <br /> 1 <br /> 1 <br /> Narrative <br />' On July 25, 1995, Va F Environmental Consultants, Inc in conjunction with F KM <br /> Groundwater Monitoring, conducted field measurements, well pumping and groundwater <br />' sampling on seven (7) groundwater monitoring wells located at this site (Figure 2) <br /> Groundwater elevations were taken from seven (7) wells prior to pumping (Table 1 & <br /> Appendix B) Monitoring wells NdW-1 through MW-7 were evacuated by means of a <br /> steam-cleaned, stainless steel bladder-type pump During the three (3) volume pump <br /> I down of each well, samples were collected to measure field pK electrical conductivity and <br /> temperature (Table 3 & Appendix B) Once stability was achieved, a minimum of three <br /> (3) well volumes were removed and samples were collected with a steam-cleaned <br />' disposable bailer The samples were then labeled and placed in an ice chest cooled with <br /> Blue Ice® <br /> The samples, bailer blanks and trip blank were then logged on a Chain of Custody <br /> (Appendix A) and transported to the State-certified laboratory, California Laboratory <br /> Services, in Rancho Cordova, California The analysis requested for the water samples <br /> was EPA method 602 for BTX&E, EPA method 5030/8015 (GCFID) for gasoline and <br /> EPA method 3510/8015 for diesel The analytes and concentrations detected are listed in <br /> Table 2 of this report <br /> Groundwater Gradient <br /> The water level measurements from the monitoring wells were used to calculate the <br /> gradient and construct a groundwater gradient map (Figure 3) The gradient this quarter <br /> ranges from 0 0002 to 0 0005 ft/ft with a predominant trend of S100W to S35CW <br />. Histoncal gradient maps are included in Appendix C <br /> I <br />
