The "sustainable confinement", a management tool for polluted site case study on Fitiuu in French Polynesia

Abstract

Since the confinement technics development, the trend used to be to search complete impermeable solutions to stop completely the transfers from or toward the polluted source. On the contrary, it can be interesting to take advantage from natural attenuation mechanisms, by using geosynthetics for example, to regulate the transfer ratio in order to obtain environmental compatible conditions. The paper presents a case study of gaseous and liquid transfer management in Bora Bora, French Polynesia.
