The attached document is a set of Grain Size Distribution Reports prepared by AMEC E&I for the Suwannee River Management District's Ichtucknee Springshed Water Quality Improvement Project (Project No. 6063140235). The reports contain detailed geotechnical laboratory test results for multiple soil samples collected from various depths across different locations, dated between 3/18/14 and 4/2/14. Each report includes a grain size distribution graph, test results showing percent finer measurements for different sieve sizes, material descriptions, and technical coefficients.

The laboratory analysis documents soil samples from depths ranging from 0.0 to 8.0 feet, with sample locations labeled as SPT-3 through SPT-32 and additional composite samples. The soil classifications are predominantly sandy, with variations including fine sand, silty fine sand, and clayey fine sand. The samples are classified using the Unified Soil Classification System (USCS) as SC (clay), SM (silty sand), and SP-SM (poorly graded sand with silt), with Atterberg Limits tested according to ASTM D 4318. The reports were checked by Michael B. Woodward, a Professional Engineer, and tested by technicians identified as AC and CM, suggesting a comprehensive geotechnical investigation to support the water quality improvement project.
