A method for preventing escape of organic contaminant material, comprising the steps of:
- collecting the organic waste material at a waste disposal site;
- substantially containing and preventing release of hazardous organic waste material from the waste disposal site;
- and
- sorbing substantially all of the hazardous organic waste material passing from the waste disposal site in an organoclay to substantially prevent escape of the hazardous organic waste material to the environment, said organoclay being the previously prepared reaction product of a quaternary ammonium salt and a smectite-type clay.
