I am also a student doing a paper, on waste management in the DR. It has been difficult but I am moving along. You need to be VERY specific with what your paper is about, and then I may be able to point you into the right direction. Which pollution are you concerned with? I can tell you now that I have not been able to locate any actual laws on the subject. Also, education and programms are just now being implemented. Let me know exactly what you are looking for and I will give you web sites I have found helpful. Most national organizations have their own websites.
