To pursue a successful soil remediation plan, the lateral <br /> and v-ertical extent of soil contamination must be defined. Following are <br /> summaries of reports to answer the question "What reporting is required for the <br /> tank owner, when only soil is believed to be impacted and there is no apparent <br /> threat to ground water?" Two reports should provide information for both the <br /> tank owner and the LIA to reach a decision about the site. They are a <br />
