2.0 GEOLOGIC SETTING
Geologic information for the project area was obtained from Geologic Map of the Mount St.
Helens Quadrangle, Washington and Oregon (Phillips 1987). According to Phillips, subsurface deposits
in the vicinity of the proposed improvements consist of alluvium. Deposits defined as alluvium typically
consist of younger, unconsolidated, stratified units of silt, sand, and gravel. In some areas alluvium may
contain interbeds of peat and organic silt. The alluvium was transported and deposited by the Columbia
and Cowlitz Rivers. This unit is typically very soft/loose to stiff/medium dense, has low to moderate
shear strength, and depending on its composition, can be moderately compressible.
The general geologic stratigraphy within the project area is relatively complex due to depositional
processes. Lateral migration of point bars, channel splays and levees have resulted in interbedded and
interfingered layers of sand and silt that vary both horizontally and vertically. The transitions are mostly
gradational, but can occur relatively abruptly. Organic material (leaves, sticks, limbs, etc.) is commonly
present within the finer-grained sediments. Logs were encountered within the alluvial deposits at the site.
Normal deposition has been punctuated by voluminous input of lahar runout and volcanic alluvium from
Holocene volcanic eruptions. Fill of variable composition and density is located within the roadway
corridors and developed areas.
The methods of field exploration effectively precluded the accurate measurement of the site
groundwater level. Based on previous explorations completed in the Mint Farm (see Appendix C), it is
anticipated that the site groundwater table is located within 5 to 10 ft of the existing ground surface.

3.0 FIELD EXPLORATION PROGRAM
Subsurface conditions at the location of the proposed Longview Regional Water Treatment Plant
(Longview RWTP) and waterline route were explored on May 8, 2009 and between August 12 and 18,
2009. The exploration program consisted of advancing five (5) exploratory borings (B-9, B-10, and
B-101 through B-103) and three (3) cone penetrometer test (CPT) soundings (CPT-101 through CPT-103)
at the approximate locations illustrated on the Site and Exploration Plan (Figures 2 and 3). The
explorations were located in the field with a hand-held GPS unit.
3.1 EXPLORATORY BORINGS
The exploratory borings (B-9, B-10, and B-101 through B-103) were advanced to depths of
between 39 and 79 ft BGS with a truck- or track-mounted drill rig and the mud-rotary drilling technique.
Borings B-9 and B-10 were advanced on May 8, 2009 while borings B-101 through B-103 were advanced
between August 12 and 14, 2009. Holocene Drilling, Inc., of Edgewood, Washington advanced the
borings under subcontract to Landau Associates.
The geotechnical exploratory program was coordinated and monitored by a Landau Associates
geotechnical engineer who also obtained representative soil samples, maintained a detailed record of the
observed subsurface soil and groundwater conditions, and described the soil encountered by visual and
textural examination. Each representative soil type observed in our exploratory borings was described
using the soil classification system shown on Figure A-1, in general accordance with ASTM D2488,
Standard Recommended Practice for Description of Soils (Visual-Manual Procedure). Logs of the
exploratory borings are presented on Figures A-2 through A-6. These logs represent our interpretation of
subsurface conditions identified during the field exploration program. The stratigraphic contacts shown
on the individual logs represent the approximate boundaries between soil types; actual transitions may be
more gradual. The soil and groundwater conditions depicted are only for the specific date and locations
reported, and therefore, are not necessarily representative of other locations and times.
Disturbed samples of the soil encountered from the borings were obtained at frequent intervals
using either a 1.5-inch inside-diameter (ID) Standard Penetration Test (SPT) split-spoon sampler or a
2.375 ID Modified California split-spoon sampler. The samplers were driven up to 18 inches (or a
portion thereof) into the undisturbed soil ahead of the auger bit with a 140-lb automatic hammer falling a
distance of approximately 30 inches. The number of blows required to drive the sampler for the final 12
inches (or portion thereof) of soil penetration, is noted on the boring logs adjacent to the appropriate
sample notation.
6/7/10 Y:\133\009.010\DATA REPORT\GDR REPORT.DOC 3-2 LANDAU ASSOCIATES
Relatively undisturbed samples of fine-grained soil encountered in the borings were obtained by
advancing a 3-inch, outside-diameter (OD), thin-walled Shelby tube into the undisturbed soil ahead of the
drill bit. The tube was advanced approximately 24 inches using a hydraulic piston sampler. After
removal of the tube from the borehole, the ends of the tube were capped and sealed. Samples collected in
this manner were submitted to Soil Technology, Inc. of Bainbridge Island, Washington for completion of
consolidation tests.
Upon completion of drilling and sampling, the boreholes were abandoned in general accordance
with the requirements of Washington Administrative Code (WAC) 173-160.
3.2 CONE PENETROMETER TESTS
The CPT program was completed between August 17 through 18, 2009. The CPT soundings
were advanced to depths ranging from between 73⅓ to 120¼ ft BGS using track-mounted CPT
equipment. In Situ Engineering, Inc. of Snohomish, Washington completed the CPT soundings under
subcontract to Landau Associates.
At each CPT sound location, a four-channel electronic cone was pushed at a rate of about 1 to 2
cm/sec. The cone was used to simultaneously record tip resistance, sleeve friction, pore pressure, and
inclination every 5 cm. Data was transmitted electronically from the cone to a receiver located at the
ground surface. Upon completion of testing, the CPT soundings were abandoned in general accordance
with the requirements of WAC 173-160.
In Situ Engineering, Inc. reduced the collected CPT data and plotted tip resistance and friction
ration (sleeve friction divided by tip resistance) as a function of sounding depth. They then used
published correlations (Robertson and Campanella 1983) to estimate soil behavior types and equivalent
Standard Penetration Test (SPT) values at each interval where data was recorded (i.e., every 5 cm). In
Situ Engineering’s detailed interpretation of soil behavior types and equivalent SPT values are presented
on Figures A-7 through A-9. Text files of the CPT test results are also included on a compact disk (CD)
on included in Appendix A.
It should be noted that the published correlations used by In Situ Engineering, Inc. to develop
their detailed logs are generally regarded as predictions of soil behavior rather than actual soil type.
Factors such as changes in stress history, sensitivity, stiffness, and void ratio will influence the soil
classifications when using the published correlations. Accordingly, actual soil types at some or all of the
CPT locations may vary from the soil types shown on In Situ Engineering’s interpreted logs.
Furthermore, the soil and groundwater conditions depicted are only for the specific dates and locations
reported and, therefore, are not necessarily representative of other locations and times.
6/7/10 Y:\133\009.010\DATA REPORT\GDR REPORT.DOC 4-1 LANDAU ASSOCIATES
4.0 LABORATORY TESTING
Natural moisture content determinations, fines content determinations, Atterberg limit
determinations, and one-dimensional consolidation tests were performed on selected samples to aid in soil
classification and the determination of engineering properties. Laboratory testing was performed in
general accordance with the ASTM standard test procedures, which are described below. The samples
were checked against the field log descriptions, which were updated where appropriate in general
accordance with ASTM D2487, Standard Test Method for Classification of Soils for Engineering
Purposes. Corrosion testing was also completed on selected samples obtained from the borings.
4.1 NATURAL MOISTURE CONTENT
Natural moisture content determinations were performed on selected soil samples recovered from
the borings in general accordance with ASTM D2216. The natural moisture content of a sample is
defined as the ratio of the mass of water lost during drying versus the total mass of the oven-dried (105ºC)
sample, assuming that the sample received by the lab is representative of the in situ moisture condition.
The results of these tests are plotted at the respective sample depth on the exploration logs, as indicated in
the column labeled “Test Data” on the summary boring logs in Appendix A and the summary test pit logs
in Appendix A.
4.2 SIEVE ANALYSIS
A grain size analyses was performed on a single soil sample obtained from borings B-10 in
accordance with ASTM D422 to provide an indication of the grain size distribution. The sample selected
for grain size analysis is designated with a “GS” entry in the column labeled “Test Data” on Figure A-3 in
Appendix A. The result of the grain size analysis is presented on Figure B-1 in the form of grain size
distribution curve.
4.3 FINES CONTENT
The fines content (the percentage of material passing the U.S. Standard No. 200 sieve) of selected
soil samples obtained from our exploratory borings were determined in general accordance with ASTM
D1140 test procedures. The percentages of particles passing the U.S. Standard No. 200 Sieve is shown as
-200=xx (percent of dry weight) at the respective sample depth in the column labeled “Test Data” on the
summary boring logs in Appendix A.
6/7/10 Y:\133\009.010\DATA REPORT\GDR REPORT.DOC 4-2 LANDAU ASSOCIATES
4.4 ATTERBERG LIMITS
Atterberg limit determinations were performed on representative soil samples obtained from the
borings in general accordance with ASTM D4318 to determine the liquid limit (LL), plastic limit (PL),
and plasticity index (PI). The results of the Atterberg limit determinations are presented on Figures B-2
and B-3. Samples in which Atterberg limit determinations were completed are designated by “AL” in the
column labeled “Test Data” in Appendix A and are also shown graphically on the summary boring logs in
Appendix A.
4.5 CONSOLIDATION TESTS
The consolidation characteristics of selected fine-grained soil samples obtained from the
exploratory borings were determined at Soil Technology, Inc. laboratory in general accordance with
ASTM D2435 test procedures. The consolidation test results are included in the Soil Technology reports,
which are included in Appendix B. Samples for which this test was completed are designated by “GT” in
the column labeled “Test Data” on the summary logs.
4.6 CORROSION TESTING
Representative soil samples obtained from the borings were subjected to a suite of tests to
estimate the corrosive potential of the near-surface soils. The corrosion testing was completed by
Analytical Resources, Inc. (ARI) of Tukwila, Washington under subcontract to Landau Associates. The
Redox Potential was determined in accordance with Method SM 2580 test procedure. The pH was
determined in accordance with the SW9045 test procedure. Sulfides were determined in accordance with
the EPA 376.2 test procedure. The Minimum Resistivity was determined in accordance with the ASTM
G 57 test procedure. Preserved total solids were determined in accordance with the EPA 160.3 test
procedure. Samples in which corrosion testing was completed are designated by “COR” in the column
labeled “Test Data” in Appendix A. The results of the testing are summarized in the main portion of this
report. The data package prepared by ARI is included as an attachment to this appendix.

Notes: 1. USCS letter symbols correspond to symbols used by the Unified Soil Classification System and ASTM classification methods. Dual letter symbols(e.g., SP-SM for sand or gravel) indicate soil with an estimated 5-15% fines. Multiple letter symbols (e.g., ML/CL) indicate borderline or multiple soilclassifications.
2. Soil descriptions are based on the general approach presented in the Standard Practice for Description and Identification of Soils (Visual-ManualProcedure), outlined in ASTM D 2488. Where laboratory index testing has been conducted, soil classifications are based on the Standard TestMethod for Classification of Soils for Engineering Purposes, as outlined in ASTM D 2487.
3. Soil description terminology is based on visual estimates (in the absence of laboratory test data) of the percentages of each soil type and is definedas follows:
4. Soil density or consistency descriptions are based on judgement using a combination of sampler penetration blow counts, drilling or excavatingconditions, field tests, and laboratory tests, as appropriate.
50% - "GRAVEL," "SAND," "SILT," "CLAY," etc. 50% - "very gravelly," "very sandy," "very silty," etc. 30% - "gravelly," "sandy," "silty," etc. 15% - "with gravel," "with sand," "with silt," etc. 5% - "with trace gravel," "with trace sand," "with trace silt," etc., or not noted.
