A paper presented by lead researcher, T. Phenrat of Naresuan University (email: email@example.com): "Laboratory-scaled Developments and Field-scaled Implementations of Using Vetiver Grass to Remediate Water and Soil Contaminated with Phenol and Other Hazardous Substances from Illegal Dumping at Nong-Nea Subdistrict, Phanom Sarakham District, Chachoengsao Province, Thailand" is well worth a careful review as the results, thus far, appear to have wide application in tropical and semi tropical countries. There are a number of interesting facets to this research.
Secondly, the research team with help from public volunteers and communities: (a) directly treated, with vetiver pontoons, phenol contaminated ponds (the first round of treated water was carried out over 2 months and with reduced and acceptable contaminant levels the water is to be used for crop irrigation), and (b) planted vetiver hedges (3 rows deep) on both sides (over 1 km) of a phenol polluted stream to clean up horizontal phenol flows from the stream.
Thirdly, the team and community planted (May 2015) vetiver hedgerows along the boundary fence of a waste disposal area, adjoining community lands, that the owners refuse entry for onsite remediation and which is polluting adjacent community related groundwater.
Lastly, this VS technical response has allowed for a tri-party collaboration - government agencies, the public, and the affected communities - that provides an excellent example of how such a low cost approach can be applied.
