Air sparge system not operational during source test. <br /> b = SVE System found shut down on 4/5 due to low temperature alarm and was restarted . Total Runtime was back-calculated from 4/9 Hour Meter Reading. <br /> c = Hour meter on SVE System was reset. Period and Cumulative Uptimes were calculated using the last SVE actual hour meter reading of 147 and AS reading of 141 . <br /> 92033 Remediation Workbook.xlsx 1 of 1 Stantec <br />
