About this file
The provided document is a geotechnical testing report for the Old Mouth Cowlitz project conducted by Materials Testing & Consulting, Inc. for the USACE - Portland. The report summarizes the grain size analysis conducted on 16 soil samples submitted on October 14, 2014. The testing followed ASTM D422 with some modifications, including the addition of No. 16 and No. 50 sieves per the client's request. The data is presented in summary tables and plots, showing the particle size distribution for the samples. No further anomalies were noted during the testing.
The related federal contract opportunity is for the Columbia River Non-Routine Clamshell Maintenance Dredging 2024, with a solicitation number of W9127N25B0004. The opportunity is being issued by the Department of the Army Corps of Engineers Engineering District Portland. The solicitation package contains the details for this upcoming dredging project, but the specific requirements are not included in the provided materials.

Old Mouth Cowlitz April 4, 2019 19S035-05 Client
1. Sixteen samples were submitted for analysis on October 14, 2014.
2. The samples were submitted for grain size distribution according to ASTM D422. The samples were prepared according to ASTM D421. The method was modified to include a No. 16 and a No.
50 sieve, per the client.
3. An assumed specific gravity of 2.65 was used in the hydrometer calculations.
4. A standard milkshake mixer type device was used to disperse the fine fraction sample for one minute.
5. One sample from another job was chosen for triplicate analysis. The triplicate data can be found on the QA summary table.
6. Due to the sandy nature of the samples, there was not enough fine material to acquire accurate hydrometer readings. The samples required curve fitting between the sand and silt fractions.
7. The data is provided in summary tables and plots.
8. There were no further anomalies in this project.
1. One sample was submitted for grain size distribution according to modified ASTM D422. The sample was prepared according to ASTM D421. An assumed specific gravity of 2.65 was used in the hydrometer calculations. A standard milkshake mixer type device was used to disperse the fine fraction sample for one minute.
2. The data is provided in summary tables and plots.
3. There were no noted anomalies during this testing..
