SUMMARY:
DERR arrived on-site and met with the Environmental Professional for Geosyntec. The purpose
of the visit was to oversee the implementation of the Remedial Action Plan. Most of the shallow
soil had been removed the day prior, except for the soil beneath the pavement. Work was limited
to breaking and removing the concrete slabs and pavement, since the trucks did not have tarps and
could not transport soil. Some of the foundation was removed for the former Quonset hut, and the
DERR observed Geosyntec screen the soil beneath the foundation with a PID. PID screening was
also biased toward darker soils, which have been observed in other areas across the site, but did
not register any hits on the PID. No laboratory samples were collected beneath that foundation.
Dust control was prioritized as wind gusts started to increase later in the day. Soils were
continuously sprayed down to prevent dust from leaving the site.
The contractor was unable to get enough trucks with tarps to remove all of the impacted shallow
soil that was now exposed after the pavement was removed. The DERR requested that all
remaining impacted soil be covered with Visqueen sheeting to prevent soil from being exposed
since it would be left in place overnight. Soils were covered and photos were sent to the DERR.
No issues were reported the following day with the status of the covering.
