Focused Corrective Measures Study for Groundwater at Site SS-45. Volume II - Appendices

摘要

This report contains the summary of Hydropunch Groundwater sample results on England AFB, Alexandria, Louisiana. Charts displaying The measurements of volatile organic compounds ares shown. The report recommends natural attenuation with institutional controls as the most cost-effective method for achieving groundwater remedial action goals. This action is appropriate. The report indicates that groundwater contamination plume at each site appears to have stabilized, horizontally and vertically, in a relatively small area from when the disposal practices that caused the groundwater contamination started 30 to 40 years ago. The proposed long-term groundwater monitoring program includes sentry wells to provide assurance of the protectiveness of human health and the environment and trend analysis wells that demonstrates the effectiveness of the natural attenuation process. However, it is suggested that the proposed number of groundwater monitoring wells be reduced.
