A mesocosm evaluation of processed drill cuttings for wetland restoration

The DC-A and the dredge treatments demonstrated similar soil physico-chemical characteristics, which fell within acceptable ranges, and were comparable to the control in supporting plant growth. DC-B under fresh conditions demonstrated a high interstitial pH (∼11.0) that became ameliorated (∼8.3) under all saline conditions. Plant photosynthetic response was minimal in DC-B under fresh conditions, but comparable to the control under saline conditions. These results are promising and warrant further evaluations under a wider range of environmental conditions prior to field implementation.
