Sheet Pile Hydraulic Barrier and Site Restoration

Rouseville, Pennsylvania ~

Elite was selected to provide environmental construction services for the installation of a barrier wall intended to prevent migration of separate phase hydrocarbons into an adjacent stream.  The project was considered high priority by our client and state environmental officials in that ongoing migration of separate phase hydrocarbons were impacting surface waters.  To access the proposed barrier wall location, vegetation along the bank of the stream was removed and sediment control measures including the placement of 210 tons of rip rap were installed.  Following site preparation, a total of 340 feet of sheet pile was driven to a depth of 35 feet below ground surface.  In conjunction with the sheet pile wall, three additional ground water recovery wells were installed on the hydraulically up-gradient side of the barrier to intercept mounding separate phase hydrocarbons.  Plumbing and control logic from the newly installed recovery wells were tied into an existing ground water treatment system located on the site.

Site restoration measures included the placement of geo-textiles impregnated with seed to promote rapid development of vegetative cover.  In addition, a total of 300 native shrubs were planted to restore the area to its original state.   Because of Elite Environmental & Petroleum Services, Inc.’s prompt response to client and state agency requests, attention to detail, timely completion and adherence to budgetary constrains, the project was considered a complete success.
