Donna Reservoir and Canal System
In 1993, the Environmental Protection Agency detected a presence of polychlorinated biphenyls in the fish at Donna Reservoir and Canal System, also known as Donna Lake, during an investigation of a disproportionate number of neural tube defects in the area, with the most likely cause being stated as being an old siphon constructed around 1928. The Texas Department of State Health Services would place a ban on fishing in the lake in 1994 due to potential public health risk, with the EPA declaring it a Superfund site and placing it on the National Priorities List in 2008. In 2020, the EPA and Texas Commission on Environmental Quality officially began removing contaminated sediments and PCBs after various rounds of fish removals, estimated to cost in total $19,000,000.
