C-Tech Environmental Labs have pioneered VOC and HC monitoring in India; the first job itself was in February 2006, at SIPCOT Cuddalore, an environmental hotspot of international ‘fame’ dubbed as Gas Trouble (I & II) by Green Peace and this was carried out for the National Environmental Engineering Research Institute, Nagpur, the premier institution for environmental engineering research and consultancy in India. The results of C-Tech were quantitative, quality assured and well received and incorporated into NEERI’s report.
