Over the last few years, illegal dumping of industrial waste and wastewater has become a major environmental problem in Thailand. It is estimated that in 2013 alone, around 1.8 million tons of hazardous industrial waste disappeared from the tracking system (Crime News Team, 2013), and likely ended up in illegal dumping sites in remote areas. As intensively reported on the news over the last two years, more than 50 cases of illegal industrial waste dumping were found in remote areas close to residential zones throughout the country, but most (40 cases) are in the eastern part of Thailand (Figure 1a) (Bootkote, 2013). Nevertheless, the most infamous illegal dumping case in Thailand is probably the dumping of phenol (C6H6O)-contaminated wastewater in a “15-rai” pond (1 rai = 1,600 m2) in the Nong-Nea Subdistrict, Phanom Sarakham District, Chachoengsao Province (Figure 1b and c). This case has gained much public and media attention since February 2012 due to several interesting and unique aspects of the incident.
