1 <br /> 5.0 Geophysics Survey <br /> A geophysics survey was conducted on the subject property to assess the possibility of USTs at <br /> the site. Traverses which ran approximately east to west, spaced ten feet apart, were established <br /> with magnetics data collected at ten foot intervals along each traverse. The background magnetic <br /> field strength was measured at about 50,000 gammas and data repeatability was good. <br /> A contour map of the intensity of the earth's magnetic field was produced from the magnetics <br /> data and used to assist in the identification and location of magnetic anomalies which might <br /> represent USTs (see Appendix G). Ground Penetrating Radar (GPR) was utilized to further <br /> investigate significant anomalies to identify their source. <br /> Only one significant anomaly was identified within the area of investigation which did not appear <br /> to be related to surface features (see Appendix H). The intensity of the anomaly as measured by <br /> the magnetometer indicated a potential UST. The GPR confirmed the anomaly but was unable <br /> to determine the exact source. <br /> 6.0 Conclusions <br /> As mentioned in Section 2.0 of this report, the Phase I Environmental assessment indicated three <br /> ' topic areas of potential environmental concern for impact on the subject properties. These were <br /> (1) UST leaks within one-quarter mile, (2) the possible presence of USTs on site and (3) the <br /> possibility of surface spills on or near adjacent sites. <br /> To address leaking USTs, soil and groundwater samples were collected from the installed <br /> groundwater monitoring well and targeted analytes were discovered to be within currently <br /> acceptable levels. <br /> 5 <br /> Wn2W1/ /L'M08I7.lp1 <br />
