2018 Construction Monitoring

Environmental monitoring for the 2018 construction includes water and air monitoring. Air monitoring is being performed around the secure landfill, water and air monitoring are being performed for the staging area during the in-river shoreline work, air monitoring is being performed around soil removal areas along the north shore of the river near the Alcoa Bridge, and water and air monitoring are being performed for the in-river capping test. These monitoring activities and results are summarized below.

 

Air Monitoring - 2018 Secure Landfill Construction and Operation

Program includes particulate monitoring using real-time meters for particulates (or dust) and volatile organic compounds (VOCs) and sampling for PCB analytical testing. Corrective action levels have been established based on levels that are safe for the community for particulates, VOCs, and PCBs. The actual monitoring results are compared to the corrective action levels to determine if adjustments in construction are needed. The air monitoring locations and tabulated results are provided below.
