Periodic field observations were conducted to check for visible presence of permanganate following ISCO injections. No actual sampling was conducted when permanganate was observed because past data has confirmed VOCs are not present when permanganate is present. Prior observations indicated permanganate has flushed through the system, therefore routine post-injection monitoring has resumed. The most recent data collected in April 2015 indicated supplemental ISCO injection may be required. Arcadis is in the process of developing a proposal for supplemental permanganate injection activities. Summary data report will be submitted to WDNR following client approval of supplemental proposal.
