Soil washing
Over 2.2M m3 of soil was excavated to create the site platform. In total over 900,000 m3 was treated of which 700,000 m3 was soil washed, which produces sand and gravel fractions for re-use.
SLIDE 7
Bioremediation
Alternative remediation techniques were also used such as bioremediation, which is good at treating organic contamination. However it takes 6-8 weeks per treatment batch. 30,000m3 of soil was treated by this process.
