LEVI N E•FRICKE <br />o Benzene, toluene, xylenes and ethylbenzene were not <br />detected in soil samples, with the exception of toluene, <br />reported in one sample at concentration of 0.065 ppm, well <br />below RWQCB allowable guideline concentrations. <br />o EDB was detected in three soil samples at concentrations <br />ranging from 0.180 and 0.370 ppm. From the absence of <br />gasoline in these samples at the Site, it appears unlikely <br />that the EDB is associated with a gasoline release at the <br />Site.
