Groundwater Treatment for Methanol and Chlorides
In August of 2018, a Limited Phase II ESA was completed to determine if there was evidence of potential contamination in connection with prior and current land use. Seven (7) boreholes were drilled and six (6) groundwater wells were installed to ensure adequate coverage of the site and ensure each APEC was investigated. Additionally, on August 20, 2018, an Electromagnetic (EM) survey was completed at the property. Based on the information collected throughout the course of the Limited Phase II ESA, soil and groundwater impacts were identified; namely methanol and chlorides from the tank farm and associated aboveground storage tanks located on the north side of the subject property.
Enviromarc supervised the installation and operation of the Ekogrid TM remediation technology between August 14, 2019 and March 29, 2020. Bi-weekly soil and groundwater analysis was completed to determine the success of the Ekogrid TM remediation technology.
Following the operation of the Ekogrid TM 20 m3 of remaining contaminated soil/debris was removed and transported to a Class II Oilfield Landfill, for disposal. Additionally, 10 m3 of waste water was removed from the site, manifested and transported by vac truck to the Full Service Terminal for disposal.
Following the success of remediation activities, all excavations were backfilled using a combination of clay and gravel with the site being recontoured to match the surrounding area.
