Abstract:
A study investigating the effects of Ogallala groundwater on the hydraulic conductivity of bentonite borehole plugs has been conducted. Clay plugs constructed from bentonite tablets hydrated with unfiltered Ogallala groundwater exhibited reduced swelling and lower hydraulic conductivity than similar plugs constructed from tablets and distilled water. Results indicate hydraulic conductivities observed in the Ogallala groundwater plugs may be governed by factors including swelling characteristics and permeant colloidal matter clogging plug pore spaces. Constant pressure injection and transient pulse testing methods were used to determine hydraulic conductivity. In constant pressure injection tests, outflow volumes may require adjustment to account for consolidation processes.
