County City Building South Bend IN 46601 Re Summary Report Soils Sampling and Testing Lot Murdocks Studebaker Corridor South Bend Indiana ATEC Project Number 21-17237 Dear Mr Pocius ATEC Environmental Consultants ATEC has completed hand auger soil sampling program at the above-referenced property The purpose of the soil sample collection and analysis was to determine if contamination may be present in the subsurface soils at this site due to drum storage area and one underground storage tank UT The objective was accomplished by advancing total of seven hand auger borings This summary report provides description of the work performed and makes recommendations based on the analytical findings Work Performed Four borings were advanced at locations surrounding the drum storage area which are designated are HA-I HA-2 HA-3 and HA-4 These samples were located adjacent to the drum storage areas Sample depth intervals for each sample were to 12 inches These soil samples were submitted for VOCs testing in the laboratory Three borings were advanced near the UST Soil samples were collected from each boring at depth between 10 and lift This sample depth interval allowed samples to be Subsidiary

reported to ATEC by Mr Calvin Murdock the dimensions of the UST are ft in length and ft in diameter comprising 1000 gallon tank Soil samples were submitted for Total Petroleum Hydrocarbons TPH testing in the laboratory All samples were collected preserved and transported to ATECs laboratory in Indianapolis Indiana for analysis following all proper chain-of-custody procedures total of seven soil samples were collected at specific locations at the project site Four samples were tested for VOCs and three samples were tested for TPH Test results for samples HA 1HA-2 HA-3 and HA-4 showed concentrations of carbon disulfide Samples HA-2 and HA- showed concentrations of petroleum constituents present Sample HA-4 showed 111- Trichloroethane TCA detected however below quantitation limits

detected NT Not tested The client should note that methylene chloride were reported as being detected in samples Methylene chloride is used as laboratory extraction solvent for various organic analyses Although the extraction and preparation processes are all performed by trained personnel in separate rooms under vented fumehood some vapors escape and are released into the laboratory atmosphere The release of these vapors into the laboratory atmosphere is basically random process dependent upon daily usage and the care and diligence of laboratory personnel involved in handling the solvents Once these compounds are released into the atmosphere they can contaminate any sample once it is removed from the sample container and exposed to the atmosphere Given the extreme sensitivity of the analytical instrumentation these compounds are often detected in low levels in environmental samples The U.S EPA1 recognizes concentrations of these contaminants up to five times the quantitation limit as laboratory artifacts Upon review of the analytical data there were no UST borings with TPH results reported above quantitation limits However several VOC parameters were detected in boring locations near the drum storage areas Conclusions and Recommendations Based on these soil test results there was no obvious evidence found to show the UST has caused gross contamination as result of past use However soil samples near the drum storage area show low concentrations of certain volatile organics Concerning this matter ATEC recommends that second round of soil samples be collected and tested for VOCs The purpose of the second round of samples is to determine the possible extent of the VOC constituents in the soils surrounding these areas ATEC recommends that this UST be properly closed to include removal according to Indiana Department of Environmental Management IDEM protocol Verbal statement made by the U.S EPA to ATEC at pre-bid conference September 1988 Our
