A significant part of the purpose of the current investigation is to try and provide an explanation for the erratic nature of the water levels measured in the existing wells. There are two conditions which prevent accurate representation of the pore pressures based on a single phreatic surface: 1.) The phreatic surface topography previously described depicts high points and ridges which indicate either numerous moisture sources or extremely variable subsurface conditions, either of which would prevent accurate representation of pore pressures with a single phreatic surface. 2.) In earlier paragraphs, the probable existence of numerous distinct aquifer zones as evidenced by widely varying water levels measured in multiple wells, located in the same vicinity, was discussed. Obviously, a single phreatic surface could not reasonably represent pore pressures in such a heterogeneous situation. Examination of the pattern of water levels indicated by measurements taken in the existing wells along with the surface observations indicates the possible existence of at least three and possibly more distinct aquifer zones as follows: a) Wells B1-3, P-3T, P-2T, P-1T2, B2-2, B2-3, BO-2 & BO-3 to the north and B2-1, B2-4, B1-1 & P-la to the south, all extend either very close to or into the natural alluvium foundation. Therefore, it would be expected that the water levels in these wells would be influenced by, if not controlled by, pore pressures in the alluvium material. In many cases, these wells show levels lower than nearby companion wells which don't extend into the foundation alluvium. There is a very curious anomaly in the vicinity of well P-1. Well P-1T2 extends into the alluvial foundation and shows the pattern described above of water levels lower than nearby wells which do not extend into the foundation. However, the level in that well (P-1T2) is elevated above what would be expected based on other piezometers which extend into the foundation. In the northern and southern areas of the pile, the water levels measured in wells which extend into the foundation show a sloping trend that somewhat follows the slope of the underlying original ground surface. This indicates the possibility that the alluvium may control pore pressures in this zone. b) Wells with tips above the refuse/foundation contact generally exhibit water levels higher than companion wells which extend into the foundation, indicating that the foundation alluvium aquifer may be separated from the refuse material by a low permeability boundary.
