Seasonal and annual <br />fluctuations of groundwater should be anticipated. <br />B.3. Laboratory Test Results <br />Laboratory test results, including moisture content, organic content and mechanical analysis (#200 sieve <br />only) tests, are suiiiiiiau:«J in Table 5. The moisture contents of the sandy fill and native soils were <br />around 3 to 15 percent, indicating the materials ranged from below to above their optimum moisture <br />contents for compaction. The higher moisture contents of noted clayey soils, ranging from 15 to <br />37 percent, are likely near or above their optimum moisture contents for compaction. <br />Table 5.
