Brief Overview:
The ARK Enterprises, Inc. was approached to perform a
pilot study of the technology using “activated” peat
moss for the treatment of petroleum contaminated soils.
Although an in-situ application could have been
performed, the decision was made to have two separate
bio-cells created and to test the technology on diesel
contamination and gas contamination.
The recommended approach for fast remediation for this
type of landfarming was to re-till the soil at specific
times and to monitor the moisture content. However, the
study was geared for worse case scenarios, there would
be no further tilling. In addition, the normal approach
for the application of the peat was to till it into the
soil. In this case, the only cutting through the clumps
of dirt and clay was with a bobcat fork. Therefore, the
peat would have to work harder to wick the oil from the
chunky soil.
DOE and FORSCOM were very pleased with the results of
this test and they are now working on a permanent
bio-cell for treatment of their petroleum contaminated
soils.
