2017 Construction Monitoring

Environmental monitoring for the 2017 construction includes water and air monitoring. Based on the current construction activities, only air monitoring is being performed around the secure landfill. Water and air monitoring for the staging area will be added once in-river shoreline work begins (likely to start later this summer).

Air Monitoring – 2017 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.
