Success In Brief

Pesticide Contamination

Addressed At Powersville

Dump Site

  The U.S. Environmental Protection Agency (EPA) encountered
much more than a municipal landfill at the Powersville site in Peach
County, Georgia. Contamination from improperly dumped hazardous
wastes and pesticides tainted an old quarry used for household gar-
bage. Chemicals migrating into area ground water threatened local
drinking water supplies. To address these issues, EPA's Superfund
program designed a cleanup strategy that included:
     Negotiating with the county and chemical companies to contain
     the hazardous wastes on site underneath a protective cover;
     Investigating reports of drinking water contamination and
     extending municipal water lines to affected residents; and
     Conducting a tailored community relations program to inform
     and educate residents about the site.
EPA's Superfund program effectively halted the further migration of
contaminants into the environment and ensured the safety of future
drinking water supplies.

                           The  Site Today
                             A multi-layer synthetic cover was
                           completed in 1992, and is containing
                           wastes at the site. Construction has
                           been completed to extend municipal
                           water lines to homes with affected
                             An alternate drinking water
                           supply will become available hi
                           spring 1993, and final inspection is
                           scheduled for fall 1993.

as a sanitary landfill. For 10
years, the landfill received

An undetermined number of
companies also disposed of

  For nearly 30 years, the
Powersville site was a sand and
gravel quarry that supplied
construction materials. In 1969,
when other county dumps were
full, Peach County began using
the pit as a landfill for household
and industrial wastes. The site
received wastes daily.
  Disposal and maintenance
activities were monitored regu-
larly by county officials. During
this time, an unknown number of
companies also dumped pesti-
cides, their containers, and chemi-
cals used in pesticide production
at the site. Such practices were
common then, since the dangers
of pesticides were not widely

       Early Efforts
       Protect Environment
       and Citizens
         During a routine
       inspection in October
       1972, Environmental
       Protection Division (EPD) officials
       from Georgia's Department of
       Natural Resources (DNR) took a
       new look at the Powersville
       dump. EPD voiced concern over
                 pesticides could be moni-
                   tored and controlled.
                       In the summer of
                       1973, following EPD's
                        specifications, Peach
                          County officials
                            designated a
                              separate one-
                              acre area for
                             the hazardous
                            wastes. They
                          lined it with five
                          feet of clay and ran
            trenches through the area to
            collect runoff and prevent pesti-
            cide migration.
               Without these precautions,
            contaminated rain water could

either have seeped into the soil
and ground water or run off the
site onto surrounding land. The
county also enclosed the area
with a cyclone fence, and posted
warning signs.
  In March 1977, EPD recom-
mended that further disposal of
these pesticides at the site be
prohibited and asked the Peach
County Board of Commissioners
to close the landfill. The EPD
expressed concern that despite
the precautions taken, the sand
and gravel floor could still permit
chemicals to filter into soil and
ground water, threatening drink-
ing supplies. In early 1979, the
county stopped accepting all
wastes at the site.

 State Officials Detect
 Ground Water Problems
   While the Powersville dump
 was still accepting wastes, local
 residents complained to EPD
 about foul odors and wastes
 blowing from the site. They also
 reported that their drinking water
 tasted bad and was often discol-
 ored. In 1983, EPD began sam-
 pling area wells for contamina-
 tion, and found that a well at the

 church next to the site was con-
 taminated with trace levels of
   In May 1983, EPD sampled
 several other wells in the area, but
 none showed evidence of con-
 tamination. EPD analysts re-
 tested the church well, and found
 that the contamination levels had
 increased. Contaminated ground
water was moving from under-
neath the site and affecting the
church's drinking supplies.  By
August 1983, EPD officials recom-
mended that church members
stop using their well water.
   EPD then contacted the EPA
Superfund program for assis-
tance. This national cleanup
program had been launched in
1980 in response to widespread
concern about hazardous waste
sites around the country.

EPA's Site Study
Assesses Threats
   In response to the state's
request, EPA proposed
Powersville to the National
Priorities List (NPL), the nation's
roster of hazardous waste sites
eligible for cleanup under the
Superfund program. In Septem-
ber 1983, EPA began studying the
ground water problem by moni-
toring the site and the surround-
ing area to determine whether the
contamination was spreading,
and if so, how fast. Samples from
monitoring wells confirmed that
ground water beneath the site
was contaminated with pesti-
cides, metals and vinyl chloride.
Based on these findings, the site
was officially listed on the NPL in
September 1984.
EPA's Community Relations
Allay Local Concerns
   Concerned by the sampling
results, residents asked that their
wells be re-tested and EPA
complied. Samples revealed
extremely low levels of contami-
nation in some private wells.
   The levels of contaminants
were within the safety standards
set by the Safe Drinking Water
Act. Nevertheless, Superfund
staff wanted to reassure the
community as to the accuracy
of the testing. Thus, EPA re-
quested that the Centers for
Disease Control (CDC) review
sampling results to ensure that
the drinking water posed no
threat to residents.
   In April 1985, CDC confirmed
EPA's findings; there was no need
to provide an alternate water
supply to the community.
   This outside analysis was just
one of the many extra steps
Superfund staff took to satisfy the
concerns  of area residents. Parties
responsible for the contamination at
the site also played a role in ad-
dressing community concerns.
Their efforts led to community
support for Superfund activities at
Powersville (see Community
Relations on page 5).

EPA Negotiates at Powersville
  One of the objectives of the
Superfund program is to obtain
private party commitments to
clean up hazardous waste sites.
During preliminary investiga-
tions, EPA identified some of the

        EPA undertook
    at the Powersville site

parties who were responsible for
hazardous wastes at the
Powersville site. One was Peach
County; another was Canadyne
Georgia, which owns Woolf oik
  EPA began negotiations with
them to perform studies at the site
and to develop cleanup options.
However, these negotiations
ended unsuccessfully, so EPA
undertook the site investigations.
The Cleanup Plan
  Following these studies in
September 1987, EPA chose a
cleanup approach which included:
  A multi-layer synthetic "cap"
  to cover the site and to prevent
  rain water from spreading
 A channel to keep rain water
  off the cover and away from
  the hazardous wastes;
 On-site monitoring wells to
  allow scientists to track the
  nature and movement of
  contaminants; and
 Extension of municipal water
  lines to serve area residents
  with affected wells, even
  though contamination was
  within acceptable drinking
  water standards.
  EPA then successfully negoti-
ated with the responsible parties
to perform the design and con-
struction of cleanup activities.
Under EPA supervision, they
began designing the protective
cover in December 1988, and
completed it in January 1991.

Cleanup Nears Completion
The Protective Soil Cover
  Following completion of the
protective cover, extra monitoring
wells were installed in 1992.
  Samples are now taken quar-
terly to test the ground water. The
site's future uses will be limited to
ensure that the cover's integrity is
not compromised. The site will be
monitored for 30 years to verify
that no future problems arise.
The Superfund program may enlist
the help of the State of Georgia to
oversee these activities.
The Water Supply
  The parties conducting the
cleanup started installing new
water lines in 1992. Water line
extensions were completed in
March 1993.
   The new lines extend from
the municipal water system of
the town of Byron nearby. All
affected residences had an oppor-
tunity to be connected free of
charge prior to March 1993.
