摘要：
A wetland naturally formed in the discharge from a copper mine tailing impoundment in Rajasthan, India. The wetland is abundantly vegetated. This study investigated changes that occurred in the seepage as it travelled 180 and 380 m (P1 and P2) through the wetland. The pH increased from 6.17 to 7.10 at P1 and 7.34 at P2 in the pre-monsoon season, 6.53 to 7.36 at P1 and 7.77 at P2 in the post-monsoon season, and from 6.20 to 6.63 at P1 and 6.89 at P2 in the winter. Contaminant removal at P2 ranged from 40 to 95%.
