Prepared by: HJF Checked by: DMY
Notes:
1. Estimated boring and well depths based on data available at the time of work plan preparation and subject to change based on site -specific conditions in the field.
2. Laboratory analyses of soil, ash, groundwater, and surface water samples will be performed in accordance with the constituents and methods identified in Tables 10 and 11.
3. Additionally, soils will be tested in the laboratory to determine grain size (with hydrometer), specific gravity, and permeability.
4. During drilling operations, downhole testing will be conducted to determine in -situ soil properties such as horizontal and vertical hydraulic conductivity.
5. * = Compliance monitoring well will be sampled during routing compliance montoring event in March 2015.
