Short-Term
  Cleanup Efforts

  To date EPA and NHDES have invest-
  ed over $ 19 million in investigation
  and interim cleanup work at the site,
  including:

  Tank/Drum Removal: Removal of
  approximate!/ I. I million gallons of
  waste oil, sludge and water; removal
  of 800 drums and cleaning, disman-
  tling, and removal of over 100 above
  ground storage tanks.The effort was
  completed in November 1997.

  Floating Oil Removal: A 120 feet
  long interceptor trench was installed
  in 1997 to capture oil seeping into
  Ketley Brook. Approximately 143 vac-
  uum extraction welts were Installed
  across the site to remove floating
  oil from the groundwater table; the
  system operated from 2000 until
  2005  and recovered over 90,000 gal-
  lons of oil. Operations ceased when
  it no longer was removing significant
  volumes of oil and the system was
  dismantled in the summer of 2008.

What is the Beede Site
Cleanup Plan?
In 2004, after receiving public comment,
EPA selected a comprehensive cleanup
plan for the site. Specifically, the plan calls
for:

• Groundwater extraction from the site,
treatment of the water, and discharge of
the water back into the water table on
the site;

• Excavation and off-site disposal of con-
taminated sediment (approximately 1,000
cubic yards) from Kelley Brook;
                      * Excavation and off-site disposal of
                      contaminated soil from the soil piles and
                      contaminated soil at depths between 0
                      and 10 feet (about 80,000 cubic yards);

                      •Treatment of approximately 70,000 cubic
                      yards of contaminated soil deeper than  10
                      feet through the use of soil vapor extrac-
                      tion technology;

                      • Long-term monitoring of on-site and
                      off-site groundwater, surface water and
                      sediment to determine if cleanup stan-
                      dards have been met; and

                      • Establishment of land use restrictions
                      (also called institutional controls) to
                      ensure future uses will not disturb any
                                       (above) Parcel I (nearly 22 acres) beginning in

                                       waste oil storagetkandling/recyding operations.

                                       Parcel 1 (19 acres) was used largely for
                                       commercial sand and gravel operations.

  Soil\&por Extraction or SVE removes

  harmful chemicals, in the form of vapors,
  from; the soil. Vapors are the gases that

  form when chemicals evaporate. The
  vapors are removed from the ground
  by applying a vacuum to pull the vapors

  out Extraction wells are drilled into the
  soil and a vacuum is attached to the wells

  and pulls the air and vapors through the
  soil and up to the surface where they are
  collected and disposed of safety. To speed
  up the process, the soil or the air injected
  into the ground may be heated, which

  helps evaporate the chemicals fester.

             most stringent cleanup standards.

             What is Currently
             Happening at the Site?

             Gathering Further Information
             Before cleanup can begin,  more informa-
             tion needs to be gathered in order to
             better design the cleanup. These efforts
             began last summer and will continue until
             the end of 2009 and primarily include:
             * additional soil and sediment sampling to
             help refine the area and depth of excava-
             tion at depths between 0 and 10 feet;

             * additional deep soil and groundwater
             samples to help refine the area and depth
             of soil vapor extraction treatment;

             • on-site and laboratory tests (e.g.,
             groundwater pump tests and tests to
             determine how porous the soil is) to
                                         collect the necessary information for the
                                         design of the soil vapor extraction and
                                         groundwater extraction and treatment
                                         systems; and

                                         • continued groundwater monitoring on
                                         and off-site to evaluate the contaminant
                                         plume and existing water supply wells.

                                         In addition to these sampling efforts, an
                                         evaluation  of potential routes of vehicular
                                         and pedestrian access to the site will also
                                         be conducted, including evaluating exist-
                                         ing access routes and constructing new
                                         access routes from Parcel 2, including a

                                         The New Hampshire Department of
                                         Environmental Services (NHDES) has
                                         been routinely monitoring residential
                                         wells in the vicinity of the Beede Site since
                                         1991. The monitoring program currently
                                         includes approximately 50 residential wells
                                         which are monitored for the presence
                                         of volatile organic compounds (VOCs).
                                         VOCs include many of the chemicals
                                         found in petroleum products (such as
                                         benzene, toluene and xylenes) and also

trichloroethylene and perchloroethylene).
Up to 17 of those wells are sampled
every three months and every three years
samples are taken from about 50 water
supply wells.

The monitoring efforts to date have
shown that seven water supply wells are
currently impacted by site-related VOCs
and only three residential wells have
VOCs present above State standards. As
a result, all those served by these three
wells are currently receiving bottled water
or carbon filtration treatment to remove
or reduce the VOC contamination to safe
levels.

In 2008, the NHDES  required the analy-
sis of a newly identified contaminant,
1,4-dioxane, at all hazardous waste sites
including the Beede Site. 1,4-dioxane is a
solvent stabilizer and is also found in many
consumer products including cosmetics,
shampoos and soap.  In February 2009, it
was reported that 1,4-dioxane was de-
tected in groundwater at the Beede Site.
The collection of water samples from
nearby residential wells began immediately
to determine if 1,4-dioxane is present at
levels above the State's 3 parts per billion
standard. Since February, samples were
taken from 27 properties and the same
seven wells that have been impacted by
other VOCs from the site have also been
impacted by  1,4-dioxane. Of those seven,
three wells currently have  1,4-dioxane at
concentrations above the State's standard
of 3 parts per billion and those house-
holds are provided bottled water regularly.
Activated carbon was changed on all
Point-of-Entry (POE) treatment systems
and samples are now taken monthly to
monitor the performance of the POEs.
Monitoring for 1,4-dioxane and VOCs will
continue as part of the site's comprehen-
sive cleanup plan.

What Will Happen  Next Year?
The information gathered in 2008 and
2009 will inform and refine the cleanup
designs. Engineering design work is sched-
uled to start in January 2010. A major
aspect of that design work will include
evaluating in detail any potential impacts
the required groundwater extraction
could have on nearby residential wells and,
if necessary, determining the corrective
actions that would be performed prior
to startup of the groundwater extraction
system. With the potential of having up
to seven wells extracting 100 to 200 gal-
lons per minute and then, after treatment,
returning that volume back into the site's
water table, clearly a full understanding is
needed to avoid unintended consequences
like disturbing area well outputs  or caus-
ing contamination in  residential wells
previously not impacted.

When Will the  Cleanup Begin?
The comprehensive cleanup is expected
to start in 2011. Aside from the ground-
water component, the soil and sediment
cleanup is slated to conclude in 2013.

Will EPA Hold  More
Public  Meetings?
As the design work gets developed, EPA
and NHDES will hold more public meet-
ings to keep the community informed,
be available to answer questions, and get
public input
What Has Been Happening
in Recent Years?
A comprehensive legal settlement agree-
ment, also called a Consent Decree,
between the federal government, the state
of New Hampshire and 101 potentially
responsible parties was lodged with the
court in April 2007 and entered as a final
order by the New Hampshire Federal
District Court in July 2008. The Consent
Decree secures a commitment from the
settling parties to finance and conduct
a comprehensive clean up of the Beede
site worth an estimated $48 million.  In
addition, the United States and the State
will recover over $ 17 million in past costs
and receive payment for up to about $9
million  in future oversight costs.

In addition, between 2001 and 2004, EPA
New England completed four"cashout"
settlements with 1,199 parties who indi-
vidually contributed relatively small vol-
umes of waste to the site ("de minimis"
parties).These settlements raised over
$ 17.3 million for site-related costs.

Who is Doing the Work?
Under the Consent Decree, the settling
parties  are required to implement the 2004
comprehensive cleanup plan. To do so, the
group has hired a project manager and an
environmental consulting company.  EPA
Site Background

The nearly 41 -arce Beede site is
located in a residential Platstow, NH
neighborhood that is served entirely
by private drinking water supply
wells.The facility was in operation
from the 1920s through August 1994
as a waste oil storage and recycling
facility.The site is contaminated
primarily with waste oil that seeped
into the ground from a variety of
sources, including a former unlined
lagoon, underground storage tanks,
aboveground storage tanks, and
numerous drums located throughout
the property.The site was added
to EPA's National Priorities (Super-
fund) List in December 1996.The
principal threats to human health
and the environment are polychlo-
rinated biphenyls (PCBs) and lead in
the shallow soil,VOCs in the deep
soil, and VOCs in the groundwater.
Lower risks are posed by PCBs and
petroleum hydrocarbon compounds
(PAHs) in a relatively small amount
of Kelley Brook sediment and VOCs
and PAHs in Kelley Brook waters.
