Notes: Stingers placed at 20-feet bgs in well MW-10, 19-feet bgs in well MW-5B, 15-feet bgs in wells IW-6 and IW-7 and 14-feet bgs in well IW-8. 1 Induced vacuum and depth to water field data was obtained, extracting from well MW-lo. Induced vacuum and depth to water field data was obtained, extracting from well MW-59. 3 Induced vacuum and depth to water field data was obtained, extracting from wells IW-6, IW-7, IW-8, and MW-5B. Recorded wellhead vacuum readings ere 16"WC and I8"WC, 78"WC and 74"WC and 69"WC and 75" WC for wells MW-5B, IW-6 and IW-7, respectively on April 29 and April 30, 2013. IW-8 was covered by a securred speed bump, therefore, readings were not obtained during. the DPE lest. Induced vacuum and depth to water field data was obtained, extracting from wells 1W-7 and IW-S. Recorded wellhead vacuum readings were 64.7"WC and 38.8"WC for well IW-7 on April 29 and April 30, 2013. IW-8 was covered by a securred speed bump, therefore, readings were not obtained during the DPE test. T;�BerneeTmding�E;�inccring�9arnes 03M DPE rev cables Page 2 of 2 STRATUS
