GROUNDWATER REMEDIATION SYSTEM OPERATION AND MAINTENANCE
Summit Environmental is providing Environmental Services to operate and maintain a groundwater treatment system in Boise, view Idaho. The groundwater treatment system is designed to treat VOCs and has been in operation for eight years. The system consists of three 40-foot deep pumping wells, diagnosis 13 area monitoring wells, three piezometers, and an air stripping treatment system designed to treat up to 300 gallons per minute. Summit Environmental staff provided measurement of groundwater levels, sampling of groundwater from the monitoring and pumping wells, evaluation and maintenance of the air stripper system, and the preparation of quarterly monitoring reports.
As part of this project, Summit Environmental staff performed pumping well maintenance. This included coordinating down-hole camera surveys to assess the condition of the well screens and quantifying the presence of iron bacteria. When well production rates fell below acceptable levels, Summit Environmental staff provided technical oversight during well redevelopment, which consisted of surge block and chemical treatment. The treatment chemicals were a proprietary blend of acids to remove the mineral scale and a catalyst to aid in the removal of iron bacteria. Groundwater production from wells redeveloped by Summit Environmental staff has increased nearly 60 percent.
