Also, as has been mentioned in previous paragraphs, during the bailing and recovery of well P-1, well P1-T1 which is about 30-feet away showed only a small response which lagged significantly behind the water level changes in P-1. This, combined with the conditions presented ir, paragraph 2 above, suggest that the water bearing zone intercepted by well P-1 can be characterized as a channel limited in horizontal extent to less than 20-feet. 4.) TheTime-Drawdown and Residual-Drawdown relationships for bailing of well P-1 showed a distinct aquifer boundary as can be seen by the change in slope indicated by the Time- Drawdown plot presented cn Plate 2 of the Appendix:. T4hile there was insufficient information to estimate the distance from the well to the boundary, the relatively short time from starting of bailing to encountering boundary effects indicated that the boundary is quite close to t`:e well. This is more characterist_c o` a channel of limited lateral e;:tent that an extensive horizontal aquifer. 5.) Piezometers 302, 303, 304 and 305 span a vertical distance of about 31-feet from elevation 4855 to 4886 but measure approximately the same level. A similar, b•~t less extensive situation was observed in the 100 series piezometers where piezometers 101 and 102 covered a vertical interval of about 12-feet from elevation 4954 tc 4866. It is revealing to note that the bcttom elevation of each of these depth intervals is practically the same, suggesting a hcrizontal boundary at about elevation 4854 controlling the groundwater flow conditions in t::e vicinity of the 100 and 300 series piezometers. Therefore, even though flow likely continues to occur through a network of channels, the pressures in this area above elevation 4854 seem to be controlled predominantly by a horizontal boundary. Similar condit_ons were observed in the 400 series piezometers where piezo-.eters 402 and 403 closely parallel each other. 6.) During the drilling and sampling, the refuse material ::as found to consist of frequently alternating zones c`_ wet and dry material. 7.) It was previously not e3 that an e:tceptior.ally hich permeability zone was encountered in drill hole No. r, again indicating the presence of h-_ghly pervicus channels. Conditions described in paragraph 5 above indicate that the piezometers contrclled by the presumed horizontal boundaries measure pervious zenes which are somewhat interconnected a:d are fed by the same source. The source appears to be a reservo_r, cr several reservoirs located deeper in the pile. The strongest 16
