L % i ENVIROMETRIX Grupe Development Company May 16, 1996 Mr. Shane Hart Page 2 of 4 reports indicated elevated levels of DDT and related compounds in five of the samples (Q1, Q2, Q3, Q5 and Q6). Only one sample (Ql) reported 1.6 parts per million (ppm) of DDT, which was above the hazardous waste threshold limit of 1.0 ppm established by the State of California. in addition,Preliminary Remediation Goals (PRGs) developed by the U.S. EPA have established PRGs for DDT in residential soil at 1.3 ppm. Levine-Fricke recommended further investigation and/or remediation of affected soil onsite. LIMITATIONS This investigation was performed in a manner consistent with the level of care and skill ordinarily exercised by members of the profession currently practicing in the same locality under similar conditions. No warranty or guarantee, expressed or implied, is made as to the conclusions and opinions included in this report. EMC has not provided, or presented, legal interpretations or opinions in this report. Appropriate legal counsel should be consulted in areas where legal interpretations or opinions are required. Soil and groundwater samples collected by EMC for laboratory analysis and observations are believed to be representative of site conditions; however, soil conditions can vary significantly between sampling points. Therefore, chemical analyses of soil and groundwater samples are only accurate at the time and place where samples are obtained. Data or values inferred to exist between sampling points are estimates and may differ from those that actually exist. Our assessment of the potential or extent of soil and/or groundwater contamination is a professional opinion based on the data obtained from these discrete sampling points The findings of this report are current as of the date of this report. However, changes in the conditions of the property can occur with the passage of time, whether they are due to natural processes or the works of man on this or adjacent properties. Therefore, the actual conditions found may change over time. In addition, changes in applicable or appropriate standards may occur from legislation or the broadening of knowledge. Accordingly, the finding of this report may be invalidated wholly or partially by changes outside EMC's control. This report is issued with the understanding that it is the responsibility of the owner, and/or his representative, to ensure that the information contained in this report are brought to the attention of the regulatory agencies as may be required by law.
