Clinic students worked with a community group in the Rio Grande Valley to spur cleanup of a local superfund site. The site is a reservoir used for subsistence fishing. Since 1993, environmental agencies have documented extremely high levels of polychlorinated biphenyls (PCBs) in the fish caught from the reservoir. Clinic students explained the superfund process to the community, developed proposals to restrict fishing while the contamination is addressed, researched cleanup methods used at similar contaminated sites, and worked with a technical expert to prepare comments on the site Remedial Investigation.
