Title: Vadose zone monitoring system installation report for McClellan AFB

Abstract

Two vadose zone monitoring systems (VZMS) have been installed at Site S-7, in Investigation Cluster 34 (IC 34), in Operable Unit A (OU A) of McClellan AFB. The two boreholes, VZMS-A and VZMS-B were instrumented at depths ranging from approximately 6 ft to 113 ft. Instruments were installed in clusters using a custom-made stainless steel cage with a spring-loaded mechanism allowing instruments to be in contact with the well bore wall once in place. Each cluster contains a tensiometer, suction lysimeter, soil gas probe and thermistor for measuring hydraulic potential, liquid- and gas-phase pressure, temperature of the formation and for collecting samples for chemical analyses in both the liquid and gas phases. Neutron probe logging is performed in two separate, smaller borings, VZMS-NP-1 and VZMS-NP-2, to obtain soil moisture content data. Preliminary details of soil gas analyses, laboratory field testing of soil samples, particle size analyses and neutron probe data are presented.
