project construction and operational water demand. Evaluation
included review of historical well logs, downhole well video logs and well locations relative to local
aquifer type and thickness.

Aquifer Zone Testing for Multiple Pilot Boreholes, Oasis, California. Performed zoned aquifer pump
and water quality testing for multiple pilot boreholes as part of a groundwater supply program at a
1,000 acre property in Oasis, California. The zone testing and sampling was performed to assess
quantity and quality of potential irrigation water, suitable for citrus crop. In addition to the zone
testing, duties included interpretation of drill cuttings and geophysical borehole logs.
