Sampling campaigns represent an important part of the project "Increasing Transparency in Industrial Pollution Management through Citizen Science." This is a joint project of the Czech non-governmental organization, Arnika Association, and the Thai partner, Ecological Alert and Recovery - Thailand (EARTH). The main goals of the project are to increase the negotiating power of communities affected by industrial pollution in their demands for corporate and government accountability and to increase transparency in industrial pollution management policies and processes in Thailand. These goals include enabling communities affected by industrial pollution to generate scientific evidence.
