Former Service Station

This Site is a former service station currently operating as a third-party owned retail petroleum service station and autobody shop in Staten Island, New York. The Site once had over 20 underground storage tanks that have since been removed. Despite years of remediation, petroleum impacts to soil and groundwater persist in the surface at the Site. Roux was awarded the project by our client in May 2018, which included the expectation to implement the existing Remedial Action Work Plan (RAWP) that was approved in 2016. The existing RAWP included steps for the design, installation, and start-up of a soil vapor extraction and air sparge (SVE/AS) system. In order to meet this goal, Roux needed to complete a pilot study and SVE/AS system design, install the SVE/AS system using existing infrastructure, replace the necessary components in order to improve efficiency and performance, and complete the SVE/AS system start-up testing in approximately six months. Despite the tight deadline, Roux’s project team was able to accomplish these tasks and successfully meet the New York State Department of Environmental Conservation (NYSDEC) regulatory requirement of having the SVE/AS system operational at the Site in January 2019. Now that the SVE/AS system is operational, the current remedial activities at the Site include monthly gauging and manual product recovery, quarterly groundwater and air sampling, and the continuous operation of the SVE/AS system. To date, the system has removed approximately 4,400 pounds of VOCs and is expected to continue operation until concentrations fall below NYSDEC standards.
