At a former manufacturing facility, Partner was retained for Environmental Remediation Consulting to perform PCB characterization sampling of flood waters associated with the on-site Wastewater Treatment Plants (WWTP), the on-site stormwater management system, and the associated National Pollution Discharge Elimination System (NPDES) which had experienced significant flooding during a heavy seasonal rainfall event.
The results of Partner’s investigation efforts revealed that PCB (polychlorinated biphenyl) contamination was present throughout the on-site WWTPs, Stormwater, and NPDES facilities. Approximately 300,000 gallons of PCB-impacted flood waters retained throughout containment structures of the WWTPs have been removed, consolidated, and/or treated on-site.
Additionally, extensive decontamination activities have been performed to facilitate decontamination/flood cleanup in and around the damaged areas of the facility. PCB-contaminated waters/oils and emulsions that flooded interior and exterior areas were successfully decontaminated as demonstrated via PCB wipe sampling.
In addition, approximately 2 million gallons of PCB-contaminated water in the stormwater retention ponds are slated for on-site treatment and eventual discharge. Partner and associated third-party contractors have collaborated to design, pilot test, install, and operate a temporary contaminated water treatment system capable of processing all contaminated liquids on-site for eventual discharge to the Publicly Owned Treatment Works facility (POTW). This system is also engineered to reduce contaminant levels prior to discharge which meet the stringent Lake Erie water quality criteria.
