Combined ISCR and ERD Remedial Approach Knocks Down PCE Concentrations in Poland

Case study highlights:

• Safe and easy co-injection of PlumeStop and S-MicroZVI
• A grid of 30 injection wells was used, with a 4m spacing between wells
• A rapid, significant drop in PCE concentrations was achieved in the entire treatment area, with no daughter products observed
• Monitoring is ongoing

Rapid groundwater treatment achieved at manufacturing plant, without daughter product build-up. At an active manufacturing plant in the region of Greater Poland, in the West of the country, historical perchloroethylene (PCE) contamination was found to be impacting both soil and groundwater. Environmental company PROTE determined that contamination originated from a number of spills and leakages that occurred over the >20 years of manufacturing on the site.The canal adjacent to the site was identified as a potential downgradient receptor vulnerable to impact from offsite advection of the contamination. Therefore, remediation was driven by a requirement to remove the site owner’s potential liability, whilst being completed within strict budgetary restrictions.
