Abstract
Single well slug tests measured hydraulic conductivity of twenty two wells at an industrial food processing facility, covering approximately 300-acres. Boring logs were studied to determine the USCS classification of the water-bearing zone, and these soil classifications were compared with the corresponding hydraulic conductivity. Correlations were not able to be made and the data were very “noisy”, resulting in no ability to use USCS soil classification for predicting hydraulic conductivity, or even approximate hydraulic conductivity. It was found that hydraulic conductivity was positively related to the linear distance from the axis of the present day major drainage swale, indicating that the majority of flow in the system occurs near the center of present day geomorphologic features. It was found that wells installed in or near the drainage swale, hydraulic conductivity decreased with increasing depth, probably due to compaction/lithification by overburden. This trend does not continue in other older formations present at the site, however. Hydraulic conductivity increased with depth in both the “lower” Carbona formation and the Neroly formation. These trends may be due to fining upward sequences, although the inability to correlate USCS classification with hydraulic conductivity, and therefore indirectly grain size makes this a difficult conclusion to draw.
