Re: Subsurface Exploration and

Field and Laboratory Testing for K-2C Border Fence Project

El Paso, Texas PSI Project No: 635-85051

Dear Mr. Zumbrunnen:

As requested, PSI has completed the on-site soil exploration and testing of the proposed K-2C Border Fence. It is understood that the project consists of the construction of approximately 6.6 miles of primary fence along the Rio Grande Levee in the vicinity of El Paso, Texas. The site for the proposed K-2C Border Fence begins at station 0+00 and ends at station 365+00 in El Paso, Texas. PSI explored the subsurface materials by drilling nine (9) soil test borings at the site to depths of 20 feet. Borings were drilled at an interval of 0.75 mile along the approximately 6.6 miles of the existing levee road with the first boring drilled at station 0+00 and the last boring drilled at station 360+00.

This report includes the results of field and laboratory testing. Boring Location Plans with the location of the borings are attached on Sheet No. A1 thru A9 and boring logs with soil/rock descriptions, stratifications, penetration resistances, locations of the samples, water level information obtained during field operations and laboratory test data are presented on Sheets No. B1 thru B9.

We appreciate the opportunity to perform this Geotechnical Study and look forward to continued participation during the design and construction phases of this project. If you have any questions pertaining to this report, or if we may be of further service, please contact our office at (915) 584-1317.

Respectfully submitted, Professional Service Industries, Inc.

Corrosion Potential

Steel/metal and concrete elements in contact with soil are subject to corrosion or degradation due to soil chemical activity. Buried metal/steel and concrete elements should be designed to resist this soil chemical activity.

Corrosion potential was evaluated by measuring electrical resistivity (ASTM G57), the laboratory chloride test (SW 846 9056), and the content pH test (EPA 9045C) of the soils from this site. Table 1 below presents general corrosive potential ratings as a function of electrical resistivity.

Table 1. Corrosive Ratings Based on Soil Resistivity

Electrical Resistivity (Ohm-cm) Corrosivity Rating Greater than 20, 000 Essentially Non-Corrosive

10,000 to 20,000 Mildly Corrosive

5000 to 10,000 Moderately Corrosive

3000 to 5000 Corrosive

1000 to 3000 Highly Corrosive

Less than 1000 Extremely Corrosive

These tests were performed on a combination of soil samples obtained from

Borings B-1 through B-9 from 0 to 5 feet depths. The results of the resistivity, laboratory chloride content test and pH test performed on these samples are shown below.

Table 2. Corrosivity Results

Resistivity (ohm-cm)

Corrosivity Based on Electrical Resistivity pH Chloride

(mg/kg) 11800 Mildly Corrosive 8.38 269

It should be realized that limited testing alone might not provide a reliable indication of corrosion potential.

Chemical Attack Potential for Degradation of Concrete

The concentration of water-soluble sulfates is considered to be a good indicator of the potential for chemical attack on concrete. Based on the ACI Manual of Concrete Practice (ACI 201.2R-10) or (ACI 318/318R-33), the amount of water-soluble sulfate in soil can be used to determine the sulfate exposure as shown in Table 3 below.

SHEET NO.: D2

Table 3. Sulfate Exposure Rating Water Soluble Sulfate in soil

(mg/kg) Sulfate Exposure

0 to 150 Negligible or Class 0 Exposure 150 to 1,500 Moderate or Class 1 Exposure

1500 to 10,000 Severe or Class 2 Exposure Over 10,000 Very Severe or Class 3 Exposure

The result of the laboratory sulfate ion concentration tests (SW 846 9056) performed on a combined soil sample obtained from Borings B-1 through B-6 is shown in Table 4 below.

Table 4. Sulfate Results

Water Soluble Sulfate in Soil (mg/kg) Sulfate Exposure

321 Moderate or Class 1 Exposure

Based on the limited testing, this sulfate ion concentration is moderate and the soils could have Class 1 sulfate exposure to concrete.

TERMS DESCRIBING CONSISTENCY OR CONDITION

COARSE GRAINED SOILS (major portion retained on #200 sieve) Includes (1) clean gravels and sands described as fine, medium or coarse, depending on distribution of grain sizes and (2) silty or clayey gravels and sands. Condition is rated according to relative density, as determined by laboratory tests or estimated from resistance to sampler.

** 140 pound hammer, 30 inch drop.

FINE GRAINED SOILS (major portion passing #200 sieve) Includes (1) inorganic and organic silts and clays, (2) gravelly, sandy, or silty clays, and (3) clayey silts. Consistency is rated according to shearing strength, as indicated by penetrometer readings or by unconfined compression tests.

NOTE: Slickensided and fissured clays may have lower unconfined compressive strengths than shown above, because of planes of weakness or shrinkage cracks in the soil. The consistency ratings of such soils are bade on penetrometer readings.

TERMS CHARACTERIZING SOIL STRUCTURE

Slickensided – having inclined planes of weakness that are slick and glassy in appearance.

Fissured – containing shrinkage cracks, frequently filled with fine sand or silt; usually more or less vertical.

Sensitive – pertaining to cohesive soils that are subject to appreciable loss of strength when remolded.

Laminated – composed of thin layers of varying colors and texture.

Interbedded – composed of alternate layers of different soil types.

Calcareous – containing appreciable quantities of calcium carbonate.

Well graded – having wide range in grain sizes and substantial amounts of all intermediate particle sizes.

Poorly graded – predominantly of one grain size, or having a range of sizes with some intermediate size missing.
