AVANTI FACILITY NWC Lafayette Street and Sample Street South Bend Indiana ATEC Project No 21-07-94-00637 1.0 INTRODUCTION ATEC Associates Inc ATEC was retained by the City of South Bend Department of Community and Economic Development to perform groundwater sampling of four monitoring wells located on the former Avanti facility at the northwest corner of Lafayette and Sample Streets The purpose of this sampling was to evaluate the current status of volatile organic compounds VOCs in the on-site wells Figure shows the project site and surrounding vicinity ATEC arrived on site August 18 1994 to sample four wells The project site consisted of vacant lot The Avanti building structure and parking lots had been demolished and removed since the last sampling event In the process of demolishing the building two monitoring wells have been destroyed and/or buried and could not be found Monitoring well MW-4 and MW-2 were located The metal protective cover and the well casing above ground level on monitoring well MW-4 had been bent to the ground With the casing bend over the well could not be sampled ATEC used hack saw to saw the metal casing and the well casing off at ground level so that the well could be sampled The well was recapped but it is not protected or secured The former parking lot at the project site has been demolished and removed The grade at the site has been lowered by approximately ft MW-2 was originally set in manhole flush with the surface elevation Since the grade around the well has been lowered the PVC well casing extends to ft Out of the ground Towards the top of the PVC piping is the cement grout and manhole cover that once set into the ground The well appeared to be undamaged The well is currently unprotected and it is vulnerable to damage

BEND INDIANA 2.0 FIELD ACTIVITIES 2.1 Groundwater Sampling On August 18 1994 groundwater samples were collected from two out of four monitoring wells Figure shows the project site and location of the monitoring wells The two monitoring wells were gauged with an electronic water level indicator before the well was sampled Prior to sampling each well was purged minimum of three well volumes of water to ensure representative groundwater sample was collected Teflon bailer was used to collect the groundwater from the well The bailer was decontaminated with non-phosphate detergent wash and tap water rinse prior to sampling each well The groundwater was collected in three 40 milliliter glass VOC vials preserved on ice and transported to the ATEC laboratory using proper QA/OC procedures and chain-of-custody protocols The groundwater samples were submitted for volatile organic compounds Table summarizes depth to water and the amount of water purged from each monitoring well Table

been damaged from demolition work at the project site In order for the well to be sampled the protective cover and the well casing were cut off at ground level The top of the casing elevation has therefore been altered Monitoring well MW-2 does not appear to have been damaged however due to the demolition work at the site the top of well casing elevation may have been altered If these wells are to be used to veri groundwater flow direction they will need to be re-surveyed Three static water level elevations are needed to accurately determine groundwater flow direction Because there are only two monitoring wells still remaining and their top of casing elevations are unknown no static water level elevation table or groundwater flow map could be generated for this sampling event 3.0 FINDINGS 3.1 VOC Analytical Test Results Groundwater samples from MW-2 and MW-4 were submitted to the ATEC laboratory for VOC analysis VOC analysis was performed on Finnigan Incos 50 GC/MS/DS system complete with Superincos Software according to SW 846 Method 8240 for Purgeable Organic Compounds Table summarizes the VOC analytical results II Table Groundwater Monitoring Well Samples Volatile

N.D None detected Analytical results for monitoring well MW-4 reveal 11 parts per billion ppb of tetrachloroethene All other VOC results for MW-2 and MW-4 are below method quantitation limits Appendix provides complete copy of the laboratory report for monitoring wells MW-2 and MW-4 3.2 Historical Groundwater VOC Results The groundwater monitoring wells at the project site have been sampled two times prior to the August 18 1994 sampling event The first sampling event occurred in November 1990 and the second sampling event occurred in February 1991 Table shows the analytical result for the detected VOC compounds over the three sampling events Note that no samples were collected for MW-i and MW-3 for the most recent August 1994 sampling event _____ vZZ vZZ 00 ZZZ zzzz .E 00r- Cd 00 11 CCCCzzzz 0.- IJI11IU 4.0 CONCLUSIONS AND RECOMMENDATIONS Analysis of the groundwater sample from MW-2 indicates that the VOC concentration in the vicinity of this well may be diminishing Historical results from MW-4 indicate that on both previous sampling events tetrachloroethene was detected however it was below the method quantitation limit of ppb The most recent result of 11 ppb would indicate that the area is still impacted by tetrachloroethene Monitoring well MW-4 is the upgradient well as determined by the groundwater flow map generated November 30 1990 The tetrachloroethene concentrations in the upgradient well may indicate possible off-site source for this constituent ATEC recommends that attempts be made to locate and properly close MW-i and MW-3 wells ATEC recommends that two new wells be installed to replace these former wells ATEC recommends that the two remaining wells and the two replacement wells be surveyed and groundwater flow map generated ATEC also recommends another round of groundwater sampling for VOCs based on the history from test results at MW-2 and the current findings at MW-4 II APPENDIX LABORATORY REPORT II ATEC Associates Inc

of the groundwater sample from MW-2 indicates that the VOC concentration in the vicinity of this well may be diminishing Historical results from MW-4 indicate that on both previous sampling events tetrachioroethene was detected however it was below the method quantitation limit of ppb The most recent result of 11 ppb would indicate that the area is still impacted by tetrachloroethene Monitoring well MW-4 is the upgradient well as determined by the groundwater flow map generated November 30 1990 The tetrachioroethene concentrations in the upgradient well may indicate possible off-site source for this constituent ATEC recommends that attempts be made to locate and properly close MW-I and MW-3 wells ATEC recommends that two new wells be installed to replace these former wells ATEC recommends that the two remaining wells and the two replacement wells be surveyed and groundwater flow map generated ATEC also recommends another round of groundwater sampling for VOCs based on the history from test results at MW-2 and the current findings at MW-4 APPENDIX LABORATORY REPORT ATEC Associates Inc Environmental Consultants 5150 East 65th Street 849 4990 FAX 842 n932 cdazardo Waste

1.0 INTRODUCTION ATEC Associates Inc ATEC was retained by the City of South Bend Department of Community and Economic Development to perform groundwater sampling of four monitoring wells located on the former Avanti facility at the northwest corner of Lafayette and Sample Streets The purpose of this sampling was to evaluate the current status of volatile organic compounds VOC5 in the on-site wells Figure shows the project site and surrounding vicinity ATEC arrived on site August 18 1994 to sample four wells The project site consisted of vacant lot The Avanti building structure and parking lots had been demolished and removed since the last sampling event In the process of demolishing the building two monitoring wells have been destroyed and/or buried and could not be found Monitoring well MW-4 and MW-2 were located The metal protective cover and the well casing above ground level on monitoring well MW-4 had been bent to the ground With the casing bend over the well could not be sampled ATEC used hack saw to saw the metal casing and the well casing off at ground level so that the well could be sampled The well was recapped but it is not protected or secured The former parking lot at the project site has been demolished and removed The grade at the site has been lowered by approximately ft MW-2 was originally set in manhole flush with the surface elevation Since the grade around the well has been lowered the PVC well casing extends to ft out of the ground Towards the top of the PVC piping is the cement grout and manhole cover that once set into the ground The well appeared to be undamaged The well is currently unprotected and it is vulnerable to damage IJI ScLULRBENb _____JhBd __________ --yg _JT ----- ----- jEEIIEic --------------- 21C7940C6.37

samples were collected from two out of four monitoring wells Figure shows the project site and location of the monitoring wells The two monitoring wells were gauged with an electronic water level indicator before the well was sampled Prior to sampling each well was purged minimum of three well volumes of water to ensure representative groundwater sample was collected Teflon bailer was used to collect the groundwater from the well The bailer was decontaminated with non-phosphate detergent wash and tap water rinse prior to sampling each well The groundwater was collected in three 40 milliliter glass VOC vials preserved on ice and transported to the ATEC laboratory using proper QA/QC procedures and chain-of-custody protocols The groundwater samples were submitted for volatile organic compounds Table summarizes depth to water and the amount of water purged from each monitoring well Table Monitoring Well Purge Volumes Former Avanti Site South Bend Indiana ATEC Project No

the protective cover and the well casing were cut off at ground level The top of the casing elevation has therefore been altered Monitoring well MW-2 does not appear to have been damaged however due to the demolition work at the site the top of well casing elevation may have been altered If these wells are to be used to verii groundwater flow direction they will need to be re-surveyed Three static water level elevations are needed to accurately determine groundwater flow direction Because there are only two monitoring wells still remaining and their top of casing elevations are unknown no static water level elevation table or groundwater flow map could be generated for this sampling event 3.0 FINDINGS 3.1 VOC Analytical Test Results Groundwater samples from MW-2 and MW-4 were submitted to the ATEC laboratory for VOC analysis VOC analysis was performed on Finnigan Incos 50 GC/MS/DS system complete with Superincos Software according to SW 846 Method 8240 for Purgeable

groundwater sample from MW-2 indicates that the VOC concentration in the vicinity of this well may be diminishing Historical results from MW-4 indicate that on both previous sampling events tetrachioroethene was detected however it was below the method quantitation limit of ppb The most recent result of 11 ppb would indicate that the area is still impacted by tetrachioroethene Monitoring well MW-4 is the upgradient well as determined by the groundwater flow map generated November 30 1990 The tetrachioroethene concentrations in the upgradient well may indicate possible off-site source for this constituent ATEC recommends that attempts be made to locate and properly close MW-i and MW-3 wells ATEC recommends that two new wells be installed to replace these former wells ATEC recommends that the two remaining wells and the two replacement wells be surveyed and groundwater flow map generated ATEC also recommends another round of groundwater sampling for VOCs based on the history from test results at MW-2 and the current findings at MW4 APPENDIX LABORATORY REPORT AlEC Associat Inc Environmental Consultants 5150 East 65th Street ARIT Indianapolis Indiana 46220-4871
