TEXICO LATERAL PIPELINE

TEXICO, NEW MEXICO

GEOMAT PROJECT NO. 222-4120R

INTRODUCTION

This report contains the results of our geotechnical exploration for the proposed Eastern New

Mexico Regional Water System (ENMRWS) Texico Lateral (TL) Pipeline project in Texico, New Mexico, as shown on the Site Plans in Appendix A of this report.

The purpose of these services is to provide geotechnical data and observations regarding:

• subsurface soil conditions

• groundwater conditions

• soil engineering properties

The data contained in this report is based upon the results of field and laboratory testing, as presented below.

PROPOSED CONSTRUCTION

We understand that the proposed ENMRWS Texico Lateral Pipeline project will consist of a new water pipeline that is expected to be approximately 4.5 miles in length. The pipeline is planned to begin at the intersection of New Mexico Highway 523 and Curry County Road D, running east to New Mexico Highway 108, and ending in the town of Texico, New Mexico.

SITE EXPLORATION

Our scope of services performed for this project included a subsurface exploration program, laboratory testing, and preparation of a geotechnical data report.

Field Exploration:

Subsurface conditions along the Texico Lateral Pipeline alignment were explored between

September 19th and October 19th, 2022 by drilling twenty-two (22) exploratory borings at the approximate locations shown on the Site Plans in Appendix A. The boring locations were

Geotechnical Data Report GEOMAT Project No. 222-4120R

ENMRWS Texico Lateral Pipeline Page 2 specified and marked in the field by Jacobs representatives. If necessary, some boring locations were adjusted to allow for drill rig access or utility line avoidance. The northings, eastings, and elevations for the boring locations were obtained from the final survey data provided to us by

Jacobs and are listed on the Boring Logs in Appendix A, having the units of US survey feet. All coordinates are on the New Mexico east state plane coordinate system, and all elevations are

NAVD88. At various locations across the alignment, some borings were terminated short of the planned depths due to auger refusal. The table below summarizes the planned boring depths and total depths reached.

The borings were advanced using a CME-55 truck-mounted drill rig with continuous-flight, 7 ¼-inch O.D. hollow-stem augers. The borings were continuously monitored by engineers from our office who examined and classified the subsurface materials encountered, obtained representative samples, observed groundwater conditions, and maintained a continuous log of each boring.

ENMRWS Texico Lateral Pipeline Page 3

Soil samples were obtained from the borings using a combination of standard 2-inch O.D. split spoon and 3-inch O.D. ring-lined barrel samplers. The samplers were driven using a 140-pound hammer falling 30 inches. The standard penetration resistance was determined by recording the number of hammer blows required to advance the sampler in six-inch increments.

Representative bulk samples of subsurface materials were also obtained.

Boring logs were prepared and are presented in Appendix A. Soils were classified in accordance with the Unified Soil Classification System described in Appendix A. Relative Drilling

Resistance (RDR) is noted on the boring logs on a scale of 1 to 5. The RDR criteria is presented in the following table.

Relative Drilling Resistance (RDR) Criteria

RDR Value Term Criteria Typical Conditions

1 Very Easy

No chatter, very little resistance, very fast and steady drill advance rate

Very soft to soft silts and clays; very loose to loose silts and sands; no gravel, cobbles, boulders or rubble

2 Easy

No chatter, some resistance, fast and steady drill advance rate

Firm to stiff silts and clays; loose to medium dense silts and sands; little or no gravel, no to very few cobbles, boulders, or pieces of rubble

3 Moderate

Some chatter, firm drill resistance with moderate advance rate

Stiff to very stiff silts and clays; dense silts and sands; medium dense sands and gravel;

occasional cobbles or rubble pieces (2-3 occurrences per 10 ft)

4 Hard

Frequent chatter and variable drill resistance, slow advance rate

Very stiff to hard silts and clays with some gravel and cobbles; very dense to extremely dense silts and sands with some gravel; dense to very dense sands and gravel; very weathered, soft bedrock; frequent cobbles and boulders or rubble pieces (3-4 per 10 ft)

5 Very Hard

Constant chatter, variable and very slow drill advance, nearly refusal

Hard to very hard silts and clays with some gravel; very dense to extremely dense gravelly sand or sandy gravel; very frequent cobbles and boulders (at least 5 per 10 feet);

weathered, very jointed bedrock

Laboratory Testing:

Samples retrieved during the field exploration were transported to our laboratory for further evaluation. At that time, the field descriptions were confirmed or modified as necessary, and laboratory tests were performed to evaluate the engineering properties of the subsurface materials.

SITE CONDITIONS

Site photographs are presented in Appendix C. The photos provide a general indication of the surface conditions along the alignment.

SUBSURFACE CONDITIONS

Subsurface condition details are shown on the Boring Logs presented in Appendix A.

Groundwater Conditions:

Groundwater was not encountered in any of the borings to the depths explored. Groundwater elevations can fluctuate over time depending upon precipitation, irrigation, runoff, and infiltration of surface water. We do not have any information regarding the historical fluctuation of the groundwater level in this vicinity.

Laboratory Test Results:

Laboratory testing was performed on select samples throughout the pipe alignment. Laboratory testing included the following:

• Sieve Analysis (ASTM C136)

• Hydrometer (ASTM D7928)

• Oven-Dried Moisture Content (ASTM D2216)

• In-Situ Moisture/Density (ASTM D7263)

• Atterberg Limits (ASTM D4318)

• Compression/Expansion (ASTM D2435)

• Swell (ASTM D4546) with Modified Proctor – Method A (ASTM D1557)

• Soil Unconfined Compressive Strength

• Chemical Testing:

- Soluble Chlorides (EPA Method 300.0)

- Soluble Sulfates (ASTM C1580-20)

- Soil Resistivity (ASTM G187-18)

ENMRWS Texico Lateral Pipeline Page 5

- pH (ASTM G51-18)

- Carbonate Content (ASTM D4373-21)

Detailed results of the laboratory testing are presented in Appendix B.

Soil Unconfined Compressive Strength Test Results:

Unconfined compressive strength tests were conducted on select samples of soil. The tests were not performed in accordance with ASTM D2166 due to the samples’ dimensions not meeting the requirements for that standard. The summary of the unconfined compressive strength results is presented in the table below.

10428 TL BH-18 5 - - -

10431 TL BH-19 7 ½ - - -

The samples from borings TL BH-18 and TL BH-19 were evaluated for suitability of unconfined compressive strength tests; however, the soils lacked enough cohesion to be able to adequately run the tests.

Chemical Test Results:

Select samples of soil were tested to evaluate the potential for the on-site soils to corrode buried metal and/or concrete. As requested, the samples were tested for pH, resistivity, soluble sulfates, and chlorides. Samples that were tested for soluble chlorides were submitted to an independent analytical laboratory. Summarized chemical testing results and complete reports of the soluble chloride results are included in Appendix B. Discussions of the soluble sulfates and resistivity results pertaining to corrode buried metal and/or concrete are below.

• Corrosion of Concrete:

The soluble sulfate contents of the samples tested are less than 0.02 percent (by weight), therefore, the soils tested may be characterized as having negligible to mild potential for corrosion (IBC Table 1904.3). According to the American Concrete Institute Building Code

318, when the sulfate content is less than 0.10 percent by weight, there are no restrictions on the type of cement to be used.

ENMRWS Texico Lateral Pipeline Page 6

• Corrosion of Metals:

Corrosion of buried ferrous metals can occur when electrical current flows from the metal into the soil. As the resistivity of the soil decreases, the flow of electrical current increases, increasing the potential for corrosion. A commonly accepted correlation between soil resistivity and corrosion of ferrous metals is shown in the following table.

Resistivity (ohm-cm) Corrosivity

0 to 1,000 Severely Corrosive

1,000 to 2,000 Corrosive

2,000 to 10,000 Moderately Corrosive

>10,000 Mildly Corrosive

The samples tested had resistivity values ranging between 500 and 3,000 ohm-cm. Based on these laboratory results and the table above, the on-site soils would be characterized as severely corrosive to moderately corrosive toward ferrous metals.
