Relevant Project Experience

• Ferg's UST Site, Sacramento, California

  Principal Engineer and Project Manager for supplemental investigations, pilot studies, a focused feasibility study, and final remedy design and implementation for MTBE impacted groundwater that was detected in a nearby municipal water supply well. Groundwater extraction/aquifer tests, air sparging tests, and in-situ ozone oxidation pilot tests were conducted prior to preparing the feasibility study and implementing the final remedy. Once considered a high priority site in a litigious state between the responsible party, oil companies, and the water district, the remediation is complete, regulatory closure has been obtained from the State, and the property can be redeveloped.

• LTD Engineering/City of Woodland Water Distribution System Modeling Surface Water Feasibility Study

  Mr. Bensch performed complex water distribution system modeling for the City of Woodland’s Surface Water Feasibility Study. The existing system consisted groundwater wells located throughout the city with distribution piping from the wells to the nearby service connections. The modeling evaluated a single source of supply from the new surface water treatment plant and considered new transmission mains and water storage tanks to deliver water throughout the city. Planning level designs and budget estimates were developed and the results of this feasibility study are currently being implemented by the City of Woodland.
