WHATCOM COUNTY LANDFILL LEACHATE INVESTIGATIONS
PHASE II SCOPE OF WORK FOR THE
CEDARVILLE LANDFILL
June 13, 1984
Based upon the results of our preliminary (Phase I) analysis of potential
impacts resulting from both the active and closed -out landfills at Cedarville, a
scope of work has been prepared which will enable the development of an appropriate
water quality protection program. Basically, the proposed Phase II effort has two
somewhat distinct objectives: 1) location and evaluation of the extent of leachate
contaminant movement; and 2) design of remedial actions. The following task de-
scriptions, organized by these objectives, provide a brief summary of the proposed
Phase II scope of work. A cost estimate by task is included.
Objective 1: Location and Evaluation of the Extent of Leachate
Contaminant Movement
Task 1 -1, Com lete Site Soils Investi ation. This task includes obtaining
additf—onal subsurface information to obtain a representative characterization of the
vertical and horizontal distribution of the low permeability perching bed underlying
the site and the extent of leachate movement. This task consists of excavating ad-
ditional backhoe test pits or shallow drill holes (5 -20' deep, primarily off -site)
and mapping the extent of the clay layer. Field conductivities will be taken where
ground water is encountered in the pits.
Task 1 -2, Drill Test Holes. This task consists of advancing three test holes
approximately 30 feet deep. The wells will be used to characterize and access the
perched water bearing zone and obtain samples of the perching layer for later
testing.
The holes will be advanced using an air rotary drill rig or cable tool rig and
six inch steel casing.
All wells will be constructed using threaded two inch PVC casing with slotted
PVC screens in the water bearing zone. The wells will then be gravel packed and
sealed with bentonite and the six inch steel casing removed. A locking steel
security casing and cap will be cemented into place at the surface. The wells will
be developed using air lift techniques to ensure hydraulic continuity between the
well and the aquifer and to minimize fines pumpage during testing and sampling.
A geologist will log the holes and supervise well construction. A site safety
plan will be developed prior to well construction and suitable site safety equipment
and protection provided for drilling and supervisory personnel.
Task 1 -3, Survey Well Head Elevations. This task consists of obtaining accurate
locations and elevations for each of the monitor wells installed and then correlating
these data with previous surveys at the site. Water levels will be measured at bi-
monthly intervals for a period of one year.
Task 1 -4, Perform Hydraulic Conductivit Testing. This task consists of ob-
taining water level draw down and recovery data for determining permeability/hy-
draulic conductivity of the monitored aquifer. Three short -term (2 -3 hour) pumping
or infiltrometer tests will be conducted on the perched aquifer. This task also
consists of conducting laboratory permeability tests on undisturbed samples taken
during drilling of the perching formation beneath the shallow aquifer.
Task 1 -5, Sample and Test Water Quality in Test Holes and Surface Seeps
Adjacent to the Landfill. This task consists of evacuating stagnant water from the
on -site shallow we s and subsequent collection, field filtering, preservation and
field and laboratory analysis of representative ground water samples. Prominent
leachate seeps will also be sampled close to the point of discharge onto the surface
and processed using the procedures outlined above. Appropriate field control and
sample chain -of- custody procedures will be utilized.
Both on -site perched ground water and seepage samples will be collected at bi-
monthly intervals for temperature, pH, dissolved oxygen and specific conductance
determinations (conductance is utilized as a leachate tracer). Sampling will con-
tinue over a period of one year. Every four months, the two samples exhibiting the
highest specific- conductance value will also be analyzed for important constituents
typical of landfill leachate. These parameters shall include chloride, sulphate,
ammonia, nitrate, cadmium, chromium, copper, iron, lead, manganese, mercury, nickel,
zinc and volatile organic priority pollutants. Organochlorine pesticide and PCB
levels will also be determined on the first set of samples (2); monitoring for
these constituents shall continue if significant concentrations are found. The
analytical methods employed shall ensure the precise and defensible characteriza-
tion of parameter concentrations.
Task 1 -6 Surface Water Sampling. This task consists of monitoring pollutant
levels in the principal dra nage stream which nearly encircles the landfill site.
Sites upstream and downstream of the landfill will be sampled every two months for
specific conductance for a period of one year. Sampling shall coincide with the
anticipated time -of- travel of the creek at the time of sampling; discharge of the
creek during sampling will be estimated. Leachate discharge quantities and dilu-
tion in the drainage stream can be evaluated with this data.
Task 1 -7, Evaluation and Anaysis of On -site Hydrogeology and Water Quality.
This task includes the determination of the major aquifer parameters with respect to
the directions and rates of flow in the perched aquifer beneath the facility. Water
quality data will be analyzed relative to the variability of leachate contaminant
transport and appropriate water quality criteria and standards. A report which
properly documents the results and evaluations will be prepared.
Objective 2: Design of Remedial Actions
Task 2 -1 Test Site Materials. This task consists of obtaining and analyzing
data for determining the suft—a-BMty of site materials for trafficability, interim
cover, capping or other operation uses. Materials testing will include gradation
and moisture holding capacity on five samples and gradation, moisture density and
compacted permeability on three additional samples. Two samples from the County's
existing borrow site will be tested for the same parameters.
Task 2 -2 Determine Underflow Volumes. This task consists of estimating under -,_
flow vo umes needed or design of a site moisture routing program which will include
surface and shallow ground water diversion. This task includes evaluating soils and
aquifer data and calculating the potential ground water volume entering the diversion
system.
Task 2 -3, Site Mapping. A site map of the existing site area will be prepared
based on aerial photography. The map will be at a scale of 1" - 50' with 2' contours.
Task 2 -4 Fill Development Plan. A plan will be prepared for the development
of the waste disposal area. The plan will include a recommended filling sequence in
which horizontal and vertical boundaries of the landfill stages or lifts will be de-
fined. Surface water control and routing associated with the filling sequences will
also be established. Cover material requirements and suitability will be evaluated
for on -site materials for uses as daily, intermediate, and final cover. The need
for obtaining off -site materials for cover use will be established and off -site
sources identified and evaluated. Materials excavation and placement for daily,
intermediate and final cover will then be defined for both on and off -site materials.
Final site topography will be established to enable the solid waste filling operation
to conform with the desired closure requirements for the landfill.
It may also be necessary to prepare a fill development plan based on the dispo-
sal of incinerator residue at the Cedarville site based on the potential for the
implementation of a resource recovery facility to serve the County. This could nec-
essitate development of separate disposal areas for residue and non - incinerated
waste.
Task 2 -5 Site Monitoring Plan Devel o ment. A site monitoring program will be
developed for the site which will include a description of the locations, frequency
and methods for long -term surface and ground water sampling. Water quality parameters
and test procedures will be defined for the analysis of the samples.
