2 065 the topography or relief is most noticeable is the area that is most suitable as a receiver soil for wastewater. The higher elevations on the site are those that are considered most suitable for subsurface treatment and disposal of wastewater. The major topographic limitation on the site is the lack of a suitable internal drainage outlet. Internal drainage is the most limiting of the factors encountered on the site. This will require careful design and installation of any system and will limit the overall suitability of the site. The topographic limitation can be overcome through careful placement of the selected wastewater treatment options. Soils The soils information required for design and development of soil based wastewater treatment systems can be determined through investigation of published literature sources and must be confirmed through actual on-site investigation. In determining the properties of the soils on any wastewater receiver site, hand auger borings must be advanced at several locations throughout the area to determine properties of the soils on the site. Soil properties investigated in the hand auger borings include: soil depth, soil color, and soil texture. Each of these are used •to characterize. a representative or typical soil profile. The hand auger borings advanced at several locations over the site indicate that there are a wide variety of soils encountered. The soils ranged in property from severely limiting to provisionally suitable for design and development of conventional or subsurface wastewater treatment systems to provisionally suitable for design and development of spray irrigation systems. Characteristic or representative soil profile descriptions for the Lignum, Herndon, and Georgeville-like soils encountered over the area proposed for wastewater treatment and disposal are included as an attachment to this report.
