000'0$ 3 heavy clay soils, and the clay mineralogy should preclude movement of waste constituents to the groundwater. Geology should pose little hazard to the design or operation of a slow rate spray irrigation system at the Bradshaw Mobile Home Park. Soils The soils information required to develop the design criteria for a slow rate spray irrigation system must address both the agronomic and engineering characteristics of the soils. This data is readily available in published literature. In addition to an examination of published literature, first-hand knowledge of the soils on the site must be determined by an individual familiar with land-based wastewater management. This on-site determination is critical to the design and operation of a slow rate spray irrigation system. The soil encountered on the proposed waste receiver site appears to be a Georgeville like sandy loam. This soil is considered well suited as a receiver for spray irrigation of wastewater onto the land. There are some minor limitations to the utilization of this soil as a receiver for pretreated waste. The primary limitation is the somewhat slower permeability of the subsoil when compared to that of the topsoil and the minor erosion potential of the topsoil and clay portion of the subsoil. This erosion potential has not been expressed on the site because the current land-use practice appears well suited for this area and watel movement over the site has been maintained very low. 1 A characteris i.c soil profile description for the Georgeville like soil is included as an attachment to this report. The Georgeville soil is the most restrictive of the soils encountered on the site. It also covers the bulk of the area intended as a receiver for wastewater. Selected properties of the Georgeville like soils encountered on the site are also presented in Table 1 below.
