BACKGROUND; This treatability study report consists of limited pages from
a study by GCA Corp. Endangerment Assessment and Feasibility Study on the
Picillo Site, Coventry, R.I. vhich reported on the change in contaminant
concentrations in several stockpiles of soils. One stockpile containing
phenol concentrations up to 870 ppm was landfarmed by spreading and
irrigating the waste with microorganisms. Other stockpiles are mentioned
but insufficient details are provided to determine treatment methods or
results.
OPERATIONAL INFORMATION; Excavated soils were stockpiled in three
impoundments. The soils in the area are mainly sand and gravel till. The
largest pile (3500 cubic yards) has PCB contamination. A second stockpile
(2000 cubic yards) which was contaminated with phenols was landfarmed by
spreading the soil on an underdrain and liner system, and irrigating the
soil. No details are provided on the microorganisms or other facts related
to this irrigation.
PERFORMANCE; Concentrations of PCBs, phenols, and volatile organics were
reduced by the treatment. In the large impoundment, concentrations of PCBs
were decreased from approximately 700 ppm to an average of 37 ppm after
3 1/2 years by the use of landfarming. Several volatile organics were also
present in this stockpile, although the concentrations were not discussed.
Landfarming in the second impoundment reduced phenol concentrations from
approximately 900 ppm to 70 ppm.
The limited data available does not allow the treatment performance to
be accurately assessed. There is no one-to-one correspondence in the
analysis of the influent and effluent concentrations. Some contaminants
reported effluent concentrations greater than the influent concentrations.

Contaminated Soil Stockpiles—
During the August 1980 remedial actions conducted at the site a
composite sample (i.e., multiple samples from an area mixed prior to analysis)
of excavated soil from the northeast trench was found to contain ?ftp Mm
PC§-1248'. Based on this information and knowledge of the wastes found, the
excavated soil from the northeast trench was placed in an impoundment
constructed in the southeast corner of tha sit*, referred to as the "PCB
Pile." This stockpile contain* approximately 3,500 cubic-yard*-of soH
contaminated with PCBs and. other orgaaic compounds. It has both a bottom and
top liner. Although the bottom liner has been ruptured as. a result of recent
sampling activities.
Following the initial sampling of the northeast trench soil, portions of
the PCB pile have been sampled on at least five occasions. In February 1984,
RI DEM and EPA conducted an extensive sampling effort of the PCB pile. During
this effort the pile was sectioned with a backhoe and 94 samples were
collected from the pile at precise stations and depths. The collected samples
were analyzed for PCBs by RI DEM and EPA. Roughly 17 percent of the samples
showed PCB concentrations greater than 50 ppm and these elevated levels were
not restricted to well-defined portions of the pile. The average
concentration detected was 36.8 ppm and the maximum concentration detected was
180 ppm. Analyses of soils from other location* onaite indicate that PCBs are
restricted to the PCB Pile*
RI DEM also collected samples for volatile erganie analysis and rtie
results indicate that 11 volatile organic compounds, including toluene and"
xylene, are present in tha PCB pile.
During the west trench excavation activities, approximately 2,000 cubic
yards of contavmwted soi¥ «ae stockpiled at th > south end of the site
adjacent to the PCB pile. This pile-is termed he "2,000 yd-* .phenol pile"
because it once contained high concentrations (970 ppm) of phenol. RI DEM
contracted with O&fr Materials to treat the phenol contaminated waste by the
use of land farming (spreading and irrigation of waste with microorganisms to
biodegrade phenol). As part of that treatment, an under drain and liner
system was constructed which is still in place." Most recent data indicate
that treatment successfully reduced phenol levels to approximately 70 ppro. in
the soil.

Contaminant Migration
The Picillo disposal site is situated within unconsolidated, shallow to
bedrock, mineral deposits. These deposits are comprised mainly of a sand and
gravel till (unstratified and unsorted glacial material deposited directly by
glacial ice). Lowland areas surrounding the site contain r*c«r»e swaap
deposits, underlain by deposits of sand, gravel, and titl. This overburden
rests upon granitic gneiss bedrock which exhibits fractures in the upper few
feet. The nature of the subsurface geology suggests a single aquifer
(water-bearing unit).
Because of the site's location on a hillslope, contaminants introduced at
the site are subject to divergent flow. A local ground water divide through
the disposal area results in the development of two contaminant plumes:
northwest and southwest. On a larger scale, there is a regional divide
separating the Roaring Brook watershed from areas to the north, including
QuidnicK Reservoir (see Figure 1-4).
The migration pathways from locations within the disposal area to
potential receptors include many transport media such as mineral deposits,
organic deposits, and surface water bodies. Contaminant plumes emanating from
the site are subject to the natural processes of dispersion, adsorption, and
degradation, which act to decrease downgradient contaminant concentrations.
The importance of each phenomenon depends on the specific environmental
