<br />was recorded by depth. Water levels in wells without loggers were measured several times <br />during the study period. <br />Water chemistrv: Water samples for chemical analysis were collected from each well in the fall <br />of2002. Samples were analyzed at the Soil and Water Testing Laboratory at Colorado State <br />University in Fort Collins, for major cations and anions. Water pH was measured in the field <br />with an Orion Model 250A pH meter, equipped with a combination electrode and calibrated with <br />fresh buffers. <br /> <br />Statistical Analyses: Correlation analysis was used to relate monitoring well water levels to <br />other wells. <br /> <br />Results <br /> <br />Well/StaffGaufJe Installation <br />Well casing lengths are listed in Table I, and their locations are show in the site map <br />(Figure I). Three wells (2,3,4) and the staff gauge (I) had continuous water level loggers. <br />Because the substrate is landslide debris, several wells were constructed from steel well points, <br />driven with a fence post pounder. However, as illustrated later, the hydraulic head was so strong <br />at this site that many driven well points functioned as piezometers. <br /> <br />Table 1.
