Launch Complex 39B
Launch Complex 39B (LC39B) is a NASA launch site located at the Kennedy Space Center, Florida. LC39B was constructed in the mid-1960s for the Apollo Space Program, was retrofitted in the mid-1970s to support the space shuttle operations, and is being reconfigured by NASA for future Orion missions. RCRA Facility Investigations and supplemental assessment activities by Geosyntec identified dissolved chlorinated volatile organic compound (CVOC) groundwater impacts encompassing an area of approximately 27 acres. Following the completion of a feasibility study, a combination of monitored natural attenuation (MNA) and air sparging was selected to address the groundwater impacts. The air sparge design prepared and implemented in 2017 targeted an approximate 9-acre area where CVOC concentrations were not anticipated to decrease via natural attenuation in a timely manner. Design objectives included: (i) treating the CVOC impacted areas to facilitate a clear transition to long-term monitoring (exit strategy); (ii) completing the remediation in a short time frame (less than 5 years) due to NASA's proposed launch schedule; and (iii) reducing the amount of time needed to complete routine operation and maintenance (O&M) activities.
