The Chemko Technical Services, Inc. Facility ("Chemko") is a RCRA Corrective Action facility. The site was nominated based on the ongoing ground water remedy and the impact to nearby receptors.
Identification of the Chemko facility as a RCRA corrective action site is relatively recent and initial site assessment was completed in 2003. The ground water contaminant plume consisting of tetrachloroethene (PCE) and its breakdown products has migrated beyond the property boundary and has impacted a domestic drinking water well. An interim measure pump and treat (P&T) system was installed for source control on the Chemko property in 2004. Monitored natural attenuation (MNA) has been selected as the interim remedy for the downgradient plume.
