6!7 Groundwater monitoring wells or piezometers would be required to more accurately determine water levels. Seasonal and annual fluctuations in groundwater levels should be expected. 3.3 Laboratory Tests Laboratory moisture content and percent passing the Number 200 sieve (P-200 content) tests were performed on selected samples recovered from the soil borings. A summary of the laboratory testing is presented in the Table 1 below. The moisture contents of the samples are also provided on the soil boring logs opposite the sample tested. Table 1.

The cohesive soils will generally be Type B soils under Department of Labor Occupational Safety and Health Administration (OSHA) guidelines, while the granular soils will generally classify as Type C soils. 4
