process.
Potential
remedial
activities
for
Title
27
closure
of
the
former
Brisbane
Landfill
are
discussed
on
pages
4.G-78
through
4.G-81.
As
discussed
regulatory
authority
for
Title
27
landfill
closure
rests
with
the
RWQCB,
which
will
determine
the
specific
technologies
to
be
used
for
landfill
closure.
Landfill
remediation
will
include
both
Final
Closure
and
Post-closure
Plans
in
compliance
with
Title
27
addressing:
(1)
prevention
of
leachates
from
entering
the
groundwater,
(2)
landfill
gas
collection
and
control
system,
and
(3)
continued
monitoring
and
evaluation.
Additionally,
proposed
development
will
be
subject
to
land
use
controls
such
as
deed
restrictions
and
require
notifications
for
any
disturbances
of
the
ground.

The
first
environmental
assessment
of
fill
was
conducted
in
1982
and
included
collection
of
soil
and
groundwater
samples.
Groundwater
in
1982
was
submitted
for
analysis
of
semivolatile
organic
compounds
(SVOCs)
in
addition
to
volatile
organic
compounds
(VOCs)
and
metals.
An
additional
investigation
was
conducted
in
1985.
Groundwater
in
1985
was
submitted
for
SVOCs,
VOCs,
and
metals;
SVOCs
were
not
detected.
Subsequent
investigations,
with
the
exception
of
the
Kleinfelder
1987
investigation,
focused
on
VOC
and
metals
contamination
in
soils
and
groundwater.
As
of
2010,
the
groundwater
monitoring
program
around
the
landfill
has
included
analysis
of
SVOCs
in
addition
to
VOCs,
metals
and
other
constituents,
from
20
groundwater
monitoring
wells
and
two
leachate
wells.
SVOCs
were
not
detected
in
the
deep
groundwater
monitoring
wells
but
were
detected
at
stable
concentrations
in
the
shallow
wells
and
at
trace
concentrations
in
the
leachate
monitoring
wells.
