DID YOU KNOW?
Near real-time telemetry air monitoring results can be viewed at asconhb.com/restart. Telemetry-based air monitors around the Site perimeter report air monitoring data in near real time during work hours (7 a.m. to 6 p.m., Monday – Friday).
Ascon’s air quality monitoring data since 2019 has consistently shown air quality has been safely below health-protective screening levels, including during active work.

SITEWIDE ACTIVITIES
FIELD WORK: Beginning Tuesday, 11/12, excavation and grading work is scheduled to begin in areas of lower odor potential in the southern area of the Site. Work crews are also scheduled to be working in the northeastern area to complete the 16-foot barrier wall at the corner of Magnolia Street and Hamilton Avenue in December.
The Ascon information table will be set up in Edison Park for the first week of work to answer community questions.

Offsite air monitoring trailers have been placed in the community to the east of the Site, in Edison Park, and near Eader Elementary and Edison High Schools.
