Table 8-4 contains a sample form for a field survey. The extent of field investigation necessary will vary depending upon specific

regulatory requirements imposed by the state, as well as the option(s) being considered (e.g., agricultural, reclamation) and the completeness of the information on site suitability, topography and other factors obtained from sources such as the SCS and USGS. Site specific information should generally include:

• property ownership information • physical dimensions of the site • overall boundaries and portion usable for land application • current and planned future land use • surface/groundwater considerations

- location and depth of wells - location of surface water (seasonal and permanent) - history of any flooding and drainage problems

groundwater seasonal fluctuations • for agricultural crops:

- cropping patterns - average yields - tillage practices - irrigation practices - use of the crop grown (food, feed, fiber or other) - vehicular access within the site

• for forest land: - age of trees - species - commercial or recreational forest - fertilizer practices - irrigation practices - vehicular access within the site
