Activity and Use Limitations

At this site, activity and use limitations that EPA calls institutional controls are in place. Institutional controls play an important role in site remedies because they reduce exposure to contamination by limiting land or resource use. They also guide human behavior. For instance, zoning restrictions prevent land uses – such as residential uses – that are not consistent with the level of cleanup. For more background, see Institutional Controls.

The Texas Department of Health (TDH) issued “Aquatic Life Order Number 9” on February 4, 1994. This order stated that “. . . the Donna Irrigation System located in Hidalgo County is declared a prohibited area for the taking of all species of aquatic life.” According to a sign posted by the TDH at Donna Lake there is a $500 fine for the possession of fish from the Site. This sign also states that “Warning, it is illegal to possess fish from this water, fish caught from this water may contain harmful chemicals.” Signs warning the public about the contaminted fish have also been placed by the EPA and the Irrigation District at various locations near the reservoir and canal system.
