The soils derived from the above-mentioned formations and Adirondack derived materials carried south by the Pleistocene glaciers a re extremely diverse. They are dominated by poorly drained, acid, shallow soils in the south and by excessively drained, productive soils of fluvial or glacial origin in the valleys to the north (Komorowski, 1994) (Figure 4). Problems concerned with nutrient runoff occur in both types of soil associations. Figure 1 illustrates the patterns of soil limitations to septic tank absorption fields throughout the watershed while Figure 4a shows soil limitations for the construction of roads and streets (Dep artment of Geography, 1994). Detailed soils maps and associated explanations are presented in Anon. (1990).
