    Track 7: Cleanup and Remediation Approaches
    In-situ remediation is among the least intensive, lowest-impact remedial options for cleanup of contaminated brownfield sites. By avoiding dig & haul operations with heavy equipment and dump trucks, the cleanup is quieter and the air is cleaner. Within the in-situ remediation arena, cleanups are getting greener. Pump & treat, air-sparge, re-circulation systems are being installed with remote monitoring to reduce carbon footprints from visits to sites, and remote monitors as well as some system infrastructure are being powered by solar panels. Bioremediation is among the greenest of cleanups - harnessing nature's power to remediate sites by promoting the environmental conditions that encourage microbial degradation. Thermal remediation is energy-intensive but very short-term, reducing footprints of cleanups - with the added benefit of using the residual heat to stimulate bioremediation and activate in-situ chemical oxidation, reducing chemical volumes and costs. Chemical sources are increasingly green - zero-valent iron is manufactured through the recycling of car engine blocks. We'll explore the reasons why in-situ remediation is the leading edge of green cleanups, and the latest exciting innovations that continue to advance the clean chemistry industry.
