John Seifert's experience includes ground-water availability studies; planning of test hole drilling programs and monitoring of test hole drilling; design, construction inspection, and testing of water wells and estimation of the effects of ground-water withdrawals. He has participated in studies regarding possible dewatering and/or depressuring associated with the mining of lignite. He has directed studies of the possible effects on the fresh ground-water system of the injection of salt or brine water into deep unconsolidated aquifers and of the possible effects of the storage of hazardous waste in a salt dome. He also has managed studies of artificial recharge using wells or spreading basins to recharge water into aquifers. He has conducted studies of specific well problems regarding either the quantity or quality of the water produced and methods for their improvement. He has worked at industrial facilities on RCRA monitoring and on the evaluation of possible remediation of shallow ground-water contamination by wood preserving chemicals. He has presented expert testimony in administrative proceedings in Texas and Nevada. The projects that he has participated in have principally been in Texas, Nevada, Arizona, Florida, Arkansas and New Mexico.
